A Note from the Editor
Duchenne Muscular Dystrophy, Genetics, the FDA and Drug Pricing When I’m not editing this journal, I am otherwise a freelance writer and editor. The majority of my work these days is focused on the biopharmaceutical industry, covering industry news, career-type articles for graduates in the life sciences, and business-related biopharma materials. Rather than mention to you the great contents of this issue—it is, go read it—or push you to push your friends and colleagues to join AGT—I’m tired of doing that and you will or you won’t, it’s up to you—I thought I would write on what to me was one of the most interesting topics I covered over the last 18 months. And conveniently, it is genetics related.
“Skipping of the exon 51 enables the truncated production of the dystrophin protein. As a result, a shorter dystrophin protein is produced, which slows the progression of DMD in patients.”
The Circus Begins This story, in its most meaningful way, started for me on January 15, 2016. At that time, there were essentially two companies in a race to get a drug approved for DMD. There are others, but they were the big two. One was Sarepta, the other was San Rafael, California-based BioMarin Pharmaceutical (BMRN). BioMarin’s drug was called Kyndrisa (drisapersen). In November 2015, the FDA’s Peripheral and Central Nervous System Drugs Advisory Committee got together to discuss Kyndrisa. Of the members, 15 out of 17 voted that they believed the company’s late-stage study lacked statistical significance. It wasn’t a particularly happy meeting, with the discussions described by The Street’s Adam Feuerstein as “often convoluted and off-target, as if they really didn’t understand the drug or Duchenne muscular dystrophy.” What happened on January 15, was that the FDA rejected the drug. It should also be noted that the November meeting was a public one, which had numerous patients and their parents testifying about their heartbreaking stories. It’s an awful disease, and one can only feel sympathy and more than a little horror at what it must be like to face it. At this point, most of the focus—certainly on the part of investors, but also of families of DMD children—shifted to Sarepta. Would the drug be approved? Would it provide, if not a cure, at least some hope for the children and families of DMD children?
Duchenne Muscular Dystrophy (DMD) DMD is a muscle wasting disease. It is caused by mutations in the dystrophin gene which is found on the X chromosome. It has an X-linked recessive inheritance pattern and is passed on by the mother (carrier). It is a progressive disease that usually causes death in early adulthood—often in the 20s, although there have been improvements in treatment, so some patients make it into their 30s and occasionally 40s. In addition to the muscle wasting aspects, serious complications include heart or respiratory-related problems. It mostly affects boys, about 1 in every 3,500 or 5,000 male children. On September 19, 2016, the FDA approved Sarepta Therapeutics (SRPT)’s eteplirsen, which now goes by the trade name Exondys 51, to treat DMD. It is the first drug to be approved to treat the underlying causes of the disease. [http:// www.biospace.com/News/victory-at-last-sarepta-stock-doublesas-the-fda/432777]
Exondys The dystrophin gene, according to Drug Development Technology, is the largest occurring in nature, and contains 79 exons. The most common mutation in DMD is in exon 51. Sarepta’s tech platform is known as “exon skipping” or “gene skipping.” Rather than try to explain this myself, I’ll just quote from Drug Development Technology, they did a good job of it: “Exondys 51 is an antisense oligonucleotide produced using Sarepta’s phosphorodiamidate morpholin oligomer (PMO) technology. The drug binds to exon 51 of dystrophin gene to enable exclusion of the exon during expression of the dystrophin gene.
Snowmageddon The FDA hearing on Sarepta’s drug was scheduled for January 22, 2016. On January 21, because of an enormous snowstorm expected to hit the East Coast, the FDA postponed the meeting that was reviewing Sarepta’s New Drug Application (NDA) for eteplirsen. [http://www.biospace.com/News/withsnowmageddon-predicted-for-east-coast-fda/406197] The previous week, at the same time it rejected BioMarin’s drug, an FDA advisory committee did not recommend approval of Sarepta’s drug. But the final decision was to be made on January

22, now postponed. As I wrote on January 21, 2016, “Early evaluation of Sarepta’s eteplirsen have criticized the trial design, efficacy, dystrophin measurement methods, and statistical analysis. In particular, Sarepta’s trial included only 12 patients. ‘It’s a different leap of faith you have to take with Sarepta,’ Ira Loss, an analyst with Washington Analysis, told BloombergBusiness last week. ‘They do have patients who are still walking around after three years. The risk is you don’t have a lot of patients.’” The meeting was rescheduled for February 26. Then it was rescheduled for April 25. Officially, it was a meeting of the FDA’s Peripheral and Central Nervous System Advisory Committee. In the biopharma industry, there is something called the PDUFA date, which stands for Prescription Drug User Fee Act. It’s the date where a decision is made on whether to approve a drug. The advisory committee’s recommendation is taken into consideration, and then a decision is made on whether or not to approve the drug for the market.
did not respond to the drug, was being disregarded by Sarepta, claiming that they weren’t expected to respond to the drug because they were at a later stage of the disease. There were also no real placebo controls to compare the results to. The company used historical data from European studies, arguing that it was unethical to withhold a potentially effective drug from the boys. The committee voted 6 to 7 against recommending the drug. The PDUFA date was then scheduled for May 26, 2016. On May 25, 2016, the FDA and Sarepta announced that the FDA was going to miss the deadline because “they are continuing their review and internal discussions related to our pending NDA for eteplirsen.” In June, the FDA requested additional information from Sarepta. [http://www.biospace.com/News/sareptas-duchenemuscular-dystrophy-drug/429860] As I wrote in August 18, 2016, in covering a discussion of the placebo effect and the drug, “In short, the FDA seems concerned that Sarepta’s clinical trial and science doesn’t meet the standards other drugs have to meet in order to be approved. The FDA is not necessarily saying the drug doesn’t work, just that it hasn’t been proven in a way that meets the bar set by the FDA.”
The Circus, Part II: Politics and the Public On March 22, 2016, two co-directors of the Center for Duchenne Muscular Dystrophy at UCLA, M. Carrie Miceli and Stanley Nelson, along with 34 additional doctors and scientists specializing in DMD, wrote a public letter to the FDA. The letter brought up two specific issues. The first: did the patients’ disease progression on eteplirsen substantially deviate from the expected course of the disease in a sufficiently reliable manner? Second: did the drug show “convincing evidence of dystrophin protein induction, the proposed mechanism of action of the drug?” One of the ways drugs are tested on DMD patients is their ability to walk for six minutes. Although that seems like a relatively objective standard, keep in mind the very real psychological effect, a form of the placebo effect, in being able to walk a specific distance if you think the drug is having an effect. The authors of the letter argued that the three-year data supported accelerated approval by the FDA. They essentially felt the drug should be approved—even if it showed pretty modest effects—and then another four years should be spent on a confirmatory trial, during which patients would be able to receive the drug. Although I’m sharing this a little out of order, in February 2016, 109 members of Congress also sent a letter to the FDA urging it to accelerate approval of a DMD drug—any DMD drug, apparently, because no specific drug was mentioned in the letter.
A Few Points To Consider Much of my coverage of this story focused on Sarepta. Sarepta is a publicly-traded company, and like many biotech companies, was in an ongoing race between getting the drug approved and what is, by investors, called either the “runway” or the “cash burn.” Both mean that Sarepta had finite funds to work with in order to keep operating, keep its staff working, keep making applications for regulatory approval, keep manufacturing even modest amounts of the drug to be used in clinical trials, etc. Wall Street was watching closely, and the company’s stock was all over the place. They were literally spending millions of dollars trying to get this drug to market, and they were running out of money. Although it wasn’t as clear at that point—it became much clearer after September—there were a lot of internal battles going on at the FDA over this drug. [http://www.biospace.com/ News/this-is-why-woodcock-oked-sareptas-dmd-drug/438063] The key players were Janet Woodcock, Director of the FDA’s Center for Drug Evaluation and Research (CDER). Another was Ronald Farkas, clinical team leader, who left the agency shortly before the drug was approved—there’s speculation he left over the controversy, but he hasn’t commented publicly, as far as I know. In addition, two more players were the agency’s acting chief scientist, Luciana Borio, and Ellis Unger, director of the office of drug evaluation. Farkas, Borio and Unger all were against approval, arguing that Sarepta did not provide substantial evidence of the effectiveness of Exondys 51. It’s important at this point, I think, to note that they weren’t saying the drug was ineffective— they were arguing that Sarepta, with its small trial and lack of placebo controls, did not prove the drug was effective in line with overall FDA guidelines for drug approval.
The Circus, Part III: Welcome Back My Friends… The FDA held its meeting on April 25, 2016, which lasted 12 hours and included discussions and presentations. There were 52 public commentators at the hearing, including several boys with DMD and their parents. Of those 52 commentators, 51 urged approval. The primary issue the FDA had with the drug was the size of the study—only 12 boys. The data on two of them, who

P.S.
Ultimately, Woodcock pushed it through, overruling her staff. The final decision then went to Robert Califf, then the FDA’s Commissioner. Among the things Woodcock apparently was taking into consideration was whether Sarepta as a company would survive the rejection financially. There is evidence that Califf had similar reservations as Borio and Unger, but sided with Woodcock. And before I conclude this rather lengthy Editor’s Note, I want you to remember how one of the U.S. presidential campaign’s hot-button issue was drug pricing. It was helped along by the so-called “Pharma Bro,” Martin Shkreli, thenCEO of Turing Pharmaceuticals, when he bought the license for antiparasitic drug Daraprim and raised its price from $13.50 to $750 per pill.
I think it should be obvious why I found this story interesting. It has a lot of ramifications for the FDA and drug approval, and it directly connects to genetics and genetics testing. But the story has spun out in other ways, and probably will continue to do so. On February 10, 2017, I wrote another story [http://www. biospace.com/ News/sarepta-under-pressure-as-marathonpharma-emflazas/446377] about a different biotech company, Marathon Pharmaceuticals. On that day, Marathon announced that the FDA had approved Emflaza (deflazacort) to treat DMD in patients five years or older. Deflazacort is a corticosteroid that has been on the market in other countries for decades. It is widely used as an antiinflammatory agent, similar to Prednisone. The drug, for example, was available in Canada. And in Canada, it was priced at $1,000 for a year’s worth of the drug. Marathon initially indicated, for the DMD indication, it was charging $89,000 for a year’s supply of the drug. I won’t editorialize on that. Feel free. On March 16, 2017, I wrote yet another article [https:// www.biospace.com/News/ptc-therapeutics-buys-marathonphar ma s/449790/source=TopBreaking], in which PTC Therapeutics (PTCT) was buying the rights to deflazacort from Marathon. Marathon appears to have decided this particular kitchen was too hot and sold the rights for $140 million in cash and stock, in addition to a potential $50 million sales bonus and royalties that could hit low-to-mid 20s. As of that writing, PTC hadn’t indicated how it would price deflazacort. Lower, would be my guess. I very much hope that Sarepta or some other company comes up with a completely effective treatment for DMD. I hope that those patients will gain access to it without going bankrupt.
Exondys 51 So, as I mentioned at the beginning of this article, the FDA approved Exondys 51 on September 19, 2016. As part of the approval, Sarepta will have to conduct a two-year, randomized controlled trial to verify the drug’s benefits. Basically, more data is needed to prove that the drug actually improves motor functions. If it fails, FDA approval could be withdrawn. But the DMD patients do have a drug, which seems to provide at least some benefit, although how much really remains unclear. It also brought up a lot of very important arguments, namely—is the bar the FDA sets for drug safety and efficacy something that is flexible and should the company’s financial status, the lack of other treatments, and public opinion effect where that bar is set? Exondys 51 has a price tag of $300,000 for a year’s treatment. I’m going to repeat that, just to make sure everyone caught it. Exondys 51 has a price tag of $300,000 for a year’s treatment. [http://www.biospace.com/News/humana-to-cover-sareptascontroversial-dmd-drug/437013] That number is based on the weight of the patient, with the recommended dose, as set by insurance company Humana, as being 30 mg/kg of body weight. The patients receive the drug once weekly. To date, insurers, for the most part, are willing to go along with it. Anthem declined, saying that it is “investigational and not medically necessary.” Humana agreed, but with strings attached. Humana agreed to cover six months of the drug if it’s covered by initial approval. Humana will cover the next six months if the patient continues to be ambulatory. Humana’s policy states: “The member must have a diagnosis of Duchenne Muscular Dystrophy with a confirmed mutation of DMD gene that is amenable to exon 51 skipping documented by: Multiplex ligation-dependent probe amplification (MLPA), OR, array comparative genomic hybridization (array CGH), OR, DMD gene sequencing. The member must be ambulatory (e.g. able to walk with assistance, not wheelchair dependent).”

Letter to the Editor Mosaic Trisomy 9p in a Patient with Mild Dysmorphic Features and Normal Intelligence
Although the survivability of patients with 9p duplications has yet to be understood, the relatively gene poor content of 9p has been suggested (Bouhjar et al., 2011; Guilherme et al., 2014). While the majority of 9p duplication patients have concomitant partial monosomies or trisomies due to inherited unbalanced rearrangements from balanced reciprocal translocation carrier parents, pure 9p duplications have rarely been reported in the literature (Zou et al., 2009). Furthermore, of those patients with reported pure whole arm 9p duplications all presented with characteristic features and intellectual disability. Adding to the literature, we report a 13-year-old female with mosaicism for a 9pter-q13 duplication with subtle dysmorphic features and normal intelligence. Although the tissue distribution of the extra abnormal chromosome 9 is uncertain, the mild clinical features can certainly be attributed to a normal female cell line. In addition, this case illustrates the limitations of microarray in discriminating mosaicism which could have significant prognostic implications.

Best Education Practices, Teaching the Next Generation of Technologists Next-Generation Sequencing In the second quarter of last year, I wrote about a nextgeneration sequencing (NGS) analysis workshop I delivered to the students enrolled in the Genetics Technology program at The Michener Institute in Toronto. The Michener Institute is one of two post-secondary institutions offering the Canadian Medical Association accredited Clinical Genetics Technology Programs in the country. Effective in 2015, the competency profile for students included the understanding of NGS— program instructors desired some exposure to the practical application of NGS analysis. We designed a workshop to provide students with the opportunity to work with NGS data as it pertains to the role of a technologist working at the bench. Students were already familiar with NGS chemistries and platforms; the goal was therefore to demonstrate the importance of supporting the analytical workflow from data generation to variant reporting. The overall reception was very positive from last year’s class. Student feedback reflected their appreciation for learning various NGS data processing steps and the chance to practice basic steps in variant interpretation. In essence, the workshop removed the black box that some have ascribed to the steps that occur after sequencing is complete. Recently, on the first week of March, my co-worker and I were invited to deliver the same workshop to the current class. We incorporated constructive feedback for areas to improve on from last year. There were two recurring comments we noted: the first was the need to better present, in a step-by-step fashion, how to analyze a variant list from variant detection to completing proper DNA and protein nomenclature based on the Human Genome Variation Society (HGVS); and second, there was interest from the faculty in divulging the steps performed after variant detection as performed by a technologist. So, generally speaking, what happens to the variant list after a technologist reviews the acceptance criteria for each variant as outlined in Figure 1. I found the first comment more challenging. As someone
experience using genetic analysis software. There are details associated with all workflows, such as software idiosyncrasies, that can muddle main teaching points. Our goal was not to focus on the use of any specific software, but to present the need for technologists to correctly filter variants and doublecheck variant calls made by NGS software because alignment algorithms do not always interface correctly with variant calling programs. We tried to simulate real clinical training through the use of a PowerPoint presentation. We were also limited to teaching examples from the workflow we employ at work; hence, a better effort was made to label slides that presented software screenshots, and on directing students to relevant pieces of information, and this meant more image customization and slide editing. The main point of delivery was to direct their attention to how sequence variations can be presented regardless of software choice and how to read sequence alignments, understand the difference between chromosome positions and corresponding positions in coding sequences. While we improved the delivery of variant calling examples, there is still a learning gap between manual sequence analysis and understanding the use of advanced analytical software. We would like to better address these topics in the future. There are many great websites and software to help with HGVS nomenclature for the working technologist, but it is essential for students to understand the fundamentals of DNA directionality, gene direction and the convention for reporting changes at the DNA and protein level using the correct reference sequences. This skill will be increasingly important as technologists handle higher-throughput genetic data. Because of interest in post variant filtering and detection, the workshop this year added a brief presentation on the process of variant interpretation, report generation and final reporting by laboratory directors. Students and faculty were interested in learning how clinical context is added to generate a meaningful

variant annotation group responsible for variant interpretation, classification of pathogenicity and report generation. The annotation team goes through a laboratory published protocol to systematically collect and determine evidence for or against pathogenicity for all filtered variants reviewed by technologists. This includes the use of commercially purchased mutation analysis software and interpreting the resources presented within, or manually accessing external databases like the Exome Sequencing Project, the Catalogue of Somatic Mutations in Cancer, and other locus specific databases. Literature searches may also be required. Collected information can include population frequencies, histology such as frequent tumour sites recorded in the database, and in silico prediction scores. If there is any relevant published actionable evidence pertaining to care management, information can be applied to the variant under investigation to guide patient care. This branch of analysis was presented to the class in the form of specialized variant filtering and classification web-based software which incorporates updated information from many credible external resources. In addition, we included laboratory defined classification schemes. The use of variant interpretationtype software assists with the automation of filtering clinically significant variants based on sequencing quality and allele frequencies, and adding clinically relevant information to determine appropriate classification of pathogenicity. Laboratory developed classification schemes may vary slightly from lab to lab, and most follow available guidelines put forth by regulatory bodies such as the American College of Medical Genetics and Genomics. Finally, variant classifications are reviewed to ensure that information accurately reflects current knowledge. For example, is the variant a pathogenic mutation with known methods of treatment or is it considered a good prognostic indicator? Conversely, is information insufficient to determine clinical significance at this time? Once clinical context is compiled neatly and checked by different members of the annotation team, report generation is triggered for director sign-out, completing the workflow outlined in Figure 1. As labs around the world generate NGS data and work to contribute and share clinical information associated with variants in specialized areas of disease and management, classification schemes can be refined and better standardized to offer the most informed prognosis, the right diagnosis and the best clinical care. Thank you to the class of 2018 for another great opportunity for continuous learning through teaching.

Cytogenetic Characterization of Myeloid Neoplasms with t(2;3)(p13-25;q25-29): An Analysis of 60 Cases Alexis V. Dowiak1,2 and Carlos A. Tirado1,3 1.

Abstract Chromosomal translocations involving the short arm of chromosome 2 (p13-25) and the distal part of the long arm of chromosome 3 (q25-29) are rare and still poorly studied to date. These abnormalities are common in myeloid neoplasms and are associated with a poor prognosis. Chromosomal abnormalities within the involved range of bands may contribute to the ectopic expression or formation of fusion genes involving the EVI1 gene, but the exact mechanism by which EVI1 affects leukemogenesis remains unclear. Herein, we report an analysis of 60 patient cases presenting various myeloid malignancies with t(2;3)(p13-25;q25-29) compiled from the Mitelman Database of Chromosome Aberrations and Gene Fusions in Cancer. In these studies, this translocation has been reported as a sole abnormality or within the context of a complex karyotype. Among the analysis in which molecular cytogenetic analysis was performed in order to assess the involvement of the EVI1 (ecotropic virus integration site 1 proton homolog) locus (n=19), 16 (84%) confirmed its rearrangement. In 37% of studies, the t(2;3) was seen as a sole abnormality (n=22). The t(2;3) was secondary in 11% of cases (n=4), and in 63% of the cases the t(2;3) had additional chromosomal abnormalities (n=38). Monosomy 7, deletion of the 5q arm, and translocations involving (9;22) were most common abnormalities in order of prevalence, occurring in 29% (n=11), 26% (n=10), and 13% (n=5) of case studies, respectively. These observations in the results of the literature on t(2;3), an anomaly not otherwise molecularly characterized, adds to the discussion of this translocation’s approximate incidence in myeloid disease, and specifically in acute myeloid leukemia (AML). The data highlights its nonrandom nature and suggests that it is a part of the myeloid spectrum of disorders. Considering the severe clinical outcome associated with this translocation, this data provides information about a cytogenetic biomarker as well as an understanding of the significance of this set of chromosomal anomalies in the development of myeloid disease.
Introduction Myeloid malignancies are clonal diseases of hematopoietic stem or progenitor cells as a result of genetic and epigenetic alterations. These diseases occur in a variety of ways, impairing the normal physiological process of different blood cell lineages to proliferate, differentiate, or undergo apoptosis. Chromosomal translocations involving the short arm of chromosome 2 and the distal part of the long arm of chromosome 3 are rare yet recurrent findings, observed in approximately 0.5% of myeloid malignancies at initial diagnosis or during disease progression, and are associated with a poor prognosis (Yamamoto et al., 2013). Such rearrangements can contribute to ectopic expression or formation of fusion genes involving the EVI1 (3q26) (ecotropic virus integration site 1 proton homolog) gene, encoding a stem cell-specific transcription factor essential in the transformation and fate of hematopoietic cells (Hinai et al., 2016). However, the exact mechanism by which EVI1 and such translocations affect leukemogenesis remains unclear. Herein, we present an analysis of 60 cases with t(2;3)(p13-25;q25-29) in various myeloid diseases that were compiled from the Mitelman Database of Chromosome Aberrations and Gene Fusions in Cancer.

This is one of the first large-scale analyses of t(2;3) (p13-25;q25-29), a rare anomaly not extensively molecularly characterized, and provides additional information about the nonrandom incidence of this translocation and its distribution in the spectrum of myeloid neoplasms. Most cases of this translocation present with concomitant abnormalities, the majority of which are recurrent and prognostically relevant in myeloid disease, predominantly monosomy -5q, 7, and t(9;22). -7 and -5q are particularly characteristic of therapy-related AML (tAML) (Breems et al., 2008; Swerdlow et al., 2008; Godley et al., 2010). A total of 90-95% of patients with CML demonstrate t(9;22)(q34;q11.2) resulting in the Ph chromosome (Van Etten, 2016) and this remains consistent with the presence of the abnormality in the included CML cases. However, t(9;22) is also present in two of the t(2;3) cases of AML. This event is more rare, with an incidence of 1% in cases of AML (Westbrook et al., 1992). Mechanistically, a review of the literature suggests that t(2;3) does not generate an EVI1 chimera, but rather juxtaposes the 5’ region of the EVI1 oncogene next to a transcriptional control element normally located in proximity of the 2p breakpoints,

to November 2015, and identified 60 previously published cases of myeloid disorders in which t(2;3)(p13-25;q29) was uncovered via various techniques.
Results Our review focused on myeloid neoplasms with the following disease breakdown: 38 cases of AML, seven cases of CML, and 15 cases of MDS, including two cases of refractory anemia (RA), three cases of refractory anemia with ringed sideroblasts (RARS), six cases of refractory anemia with excess blasts (RAEB), and one case of chronic myelomonocytic leukemia (CMML). t(2;3) existed as the sole abnormality in 22 cases and with concomitant abnormalities in 38 cases (Figure 2). In the latter group, t(2;3) was a primary abnormality in five of 38 cases (13%), a secondary abnormality in four (11%), and it is significant to note that for the other 29 (76%) of the reviewed complex karyotypes, it could not be determined if t(2;3 was a primary or secondary abnormality. The most common additional abnormalities reported were monosomy 7 (occurring in 29%), deletion of the 5q arm (26%), and translocations involving the Philadelphia chromosome t(9;22) (13%). Ideograms to illustrate the frequencies of observed quantitative and structural aberrations are shown in Figure 3 and Figure 4, respectively. Among the 19 cases in which molecular cytogenetic analysis was performed in order to assess the involvement of the EVI1 locus, 16 (84%) confirmed its rearrangement. In addition, in seven of these cases, EVI1 expression level was assayed by real-time PCR, which confirmed quantitatively aberrant expression relative to normal control samples from healthy donors in all cases. These results and the presented data illustrate the

Both structural and numerical abnormalities were included, and were counted on a per chromosome per case basis. Abnormalities on chromosome 2 and 3 presented above were concomitant with the translocation. In the case of multiple marker chromosomes in one case, it was quantified as one secondary abnormality for the table.

Review Cytogenetic Characterization of Myeloid Neoplasms with t(2;3)(p13-25;q25-29): An Analysis of 60 Cases
Figure 3. Ideograms illustrating the frequency of quantitative aberrations associated with cases of t(2;3) (p13-25;q25-29) translocations. Losses are drawn in red on the left side, gains in green on the right side of chromosomes. Chromosomes 1, 16, and Y ideograms are all omitted from the figure because no abnormalities were reported in our study.
resulting in consequent overexpression of EVI1 (Buonamici et al., 2003; Trubia et al., 2006). Using this suggested model, maturation would become arrested and leukocytes would proliferate, both of which would induce leukemogenesis. This is consistent with the distinct myeloid phenotype and additional clinical characteristics observed across other hematological malignancies that display EVI1 activation or 3q26 rearrangements, including monosomy 7, trilineage dysplasia, thrombocytosis, disturbed megakaryopoiesis, and an unfavorable clinical course. EVI1 can be rearranged with a variety of other partner genes (Haferlach et al., 2012). An evaluation of the literature present little evidence to describe the genes on the 2p arm that may be essential for aberrant expression of EVI1 or affect its overexpression. Our sample of cases displays a wide and variable range of involved breakpoints on the proximal arm of chromosome 2 from 2p13-2p25. To help narrow in on the breakpoints that are most frequently represented across the cases collected in the present study, and by default, most likely to be involved, ideograms of chromosome 2 in Figure 1a highlight that the region 2p21-2p23 (as opposed to 2p13-2p25) may require the most attention in future investigations, especially those seeking to explain the mechanism that might be involved. Both Trubia et al. and Yamamoto et al. reported involvement of the thyroid adenoma-associated gene (THADA) on 2p21 in 2 (n=6) cases with t(2;3)(p21;q26) (Trubia et al., 2006, Yamamoto et al., 2013). Our results, with the second greatest frequency (27) of breaks on 2p21, are consistent with this hypothesized involvement. Considering the severe clinical outcome associated with this translocation, further investigation of the molecular mechanisms by which it contributes to carcinogenesis, its interplay with concomitant abnormalities, and its diagnostic and prognostic implications is warranted.

Letter from the President Greetings, All You Genetic Technology Professionals! I bet you thought you got rid of me! Not so fast! I want to make sure all of you have heard that the 4th Edition of the AGT Technical Manual is now available for purchase!!!! Hallelujah and Mazel Tov!!!! It was a decade in the making, but it was definitely worth the wait. I can’t wait to touch it! If you think I am anxious to get my hands on it, how do you think the editors feel? That wasn’t thunder you heard last week. That was a collective sigh of relief, from sea to shining sea, and even from heaven!! One of the editors, Helen Lawce, wrote a history of the AGT manual, from her point of view, and shared it on Facebook. It’s too good not to include in this journal. I place it here, for your reading pleasure. AGT Manual history from my view, by Helen Lawce. Today, Wiley will have the 4th edition of the AGT Laboratory Manual available for purchase and delivery. It has been a long road to travel, and I think back on the ten-years-plus that it took to produce, I feel many emotions: wonder, gratitude to the dozens of people who helped without compensation, awe that it is finally final, pride, that it is the resource we wanted it to be, and love, both for the people I worked with and the work itself. My coworker Judy Canham at UCSF had an idea when we worked there together in the 1970s that we should start an organization for cytogenetic technologists and create a book of laboratory methods. She was in disbelief that the techniques we used in our lab were not published all together in one place, and as she was being trained, she became acutely aware of the need for a reference. She and a handful of other like-minded techs from Northern California made the dream of an organization come true, and Judy became the first president of the new Association of Cytogenetic Technologists (ACT, now AGT). Marilyn Arsham of New York and I undertook the project of the book, the ACT Technical Manual (now AGT Cytogenetics Laboratory Manual). The first edition was an adventure, a self-published, manually-typed manuscript bound in a loose-leafed binder. Marilyn compiled the laboratory methods, and we along with other volunteers, wrote the chapters. It was meant to be both a training resource and a laboratory reference. In the introduction we likened it to Donald Duck's nephews' *Junior Woodchuck Guide, which was such a wonderful resource that one could look up any question, including the safest ship passage through the Straits of Doomgurgle in a storm. I typed most of it myself on a snazzy rented IBM Selectric typewriter. We used 12-by-17-inch paper and had the printer copy it on 8.5-by-11-inch paper to reduce the font size and make the book smaller and cheaper. I remember my husband and I were racing horses in Mexico, when I wrote the Microscopy chapter in Juarez, in a tackroom, with a pen and yellow pad, while we were waiting to go to post or for an exercise rider to show up. The book cost members $20, about the price of a pair of running shoes back in the 1980s, and Denise Sivhonen and I wrapped, addressed, and mailed them out ourselves. At the time we used my personal mailing address to collect the money, and later the California Franchise Tax Board tried to ask me to pay income taxes on the sales. Luckily, ACT had a lawyer by then who was able to explain to the tax board that I did not make any money from the sales.

Association Business The second edition was edited by Margaret Barch, and we actually used word processing computers to write our chapters, and a real publisher did a hardbound book for us. The computer I did my chapters on was a hand-medown TRS-80 that my dad gave me when he got a better one. The publisher received my floppy discs with the chapters, but the TRS-80 code did not work for them, and they had me print everything so they could scan it into their software program. This resulted in some pretty funny typos, such as hypnotic solution instead of hypotonic solution, and I received a number of letters to point this out. I tried to laugh, but some jokes are funnier for the person who was not simultaneously writing, learning computerese, and struggling with a Tandy Radio Shack Tinkertoy computer that the publisher could not even use. The third edition, edited by Margaret Barch, Turid Knutsen, and the great Jack Spurbeck, was again a computergenerated, professionally-produced book, but the illustrations were all still made by photographic means. We added the Overview chapter, covering a sort of "day in the lab" description of what a cytogenetics technologist does with samples that come through the door from receipt to completion of the different tests. This chapter was well received by students and pathology residents, for whom cytogenetics appeared as some kind of occult magic performed by people too busy to share their secrets except in small sub-sections that did not intuitively connect with the other bits. We also added a chapter on FISH, and like many things scientific, it was outdated before the book even went to the publisher. This third edition has been the only available manual since it was published in 1995. In 2005, AGT announced that they would be doing the 4th edition, and Marilyn Arsham (1st edition editor), Margaret Barch (2nd and 3rd edition editor), and I (1st edition co-editor), dubbed the triumvirate by Pat Dowling, volunteered. Little did we dream in our wildest imaginations that the book would take more than a decade to be published. That it would take three years of battling to get permission to use the ISCN diagrams. That we would have authors retract chapters that we ended up rewriting ourselves, that children would be born to some authors and grow most of the way up, or that contributors, including one of us, would pass away before it was in print. Since it had been several computer iterations since the third edition, we could not just edit what we had on those floppy discs, as the world had moved on to other data storage methods and there was no longer hardware that could read the discs. For many chapters, I used a line-by-line scanner to copy the text into Word from a copy of the book. Many more humorous typos were made, and hopefully found and corrected by many proofreaders' eyes. We scanned the illustrations that were scannable to make tifs. We sent the text to volunteers who made many great suggestions, rewrote, and repeated. A wonderful bio illustrator, Gret Boyd, helped us make new illustrations for three chapters, and was invaluable for the chromosome identification chapter, a new addition to the book. So we hope that the fourth edition is all we meant it to be, and that it inspires many in the field, and many others in related fields. We know that parts of it are already outdated. The microarray field may have to make a dedicated, updatable volume. More and more automation and robotics will be introduced, and perhaps robots will even make our slides and stain them for us. If you read this note before the meeting, I sincerely hope that I will see many of you in person at the AGT annual conference at the Union Station Hotel in St. Louis, MO from June 15 -17. If you came to the meeting and are reading this after, it was a pleasure seeing you in St. Louis! If you didn’t come to the meeting and are reading this after June 17, you missed a good time!!! Good luck, Jason!!!

The Journal of the Association of Genetic Technologists The Journal of the Association of Genetic Technologists is a peer-reviewed journal, and scientific materials for publication containing original research will be reviewed by independent referees. Manuscripts that require revision or that contain major editorial changes will be returned to the senior author of the article. Materials submitted will not be retained following publication nor will photographs, disks, or hard copies of manuscripts be returned to authors. Rejected manuscripts will not normally be returned, although an effort will be made to return original photographs and prints. Manuscript content is the responsibility of the author(s). All articles published, including editorials, letters, book reviews, invited articles, Brain Ticklers, columns, and reviews, represent the opinions of the authors and do not reflect the official policy of AGT or the institution with which the author is affiliated unless specified by the author. AGT, its members, and the editor of The Journal of the Association of Genetic Technologists make no warranty and assume no liability with respect to the information contained herein.
Information For Authors The Journal of the Association of Genetic Technologists is pleased to consider manuscripts that describe experience with cytogenetics, molecular genetics, or biochemical genetics and the application of these disciplines. Submitted manuscripts must be typed, preferably double-spaced, using a 12 point font and 1” margins. In addition to the original, three copies of the manuscript and camera-ready illustrations must be submitted to the editor-in-chief. Items to be italicized or enhanced (bold, underlined) should be clearly indicated. The conversion factor for print equivalency is as follows: two double-spaced typed pages equal approximately a one-half typeset page. Authors may supply the material on a 3½” disk, preferably in Microsoft Word, WordPerfect, or ASCII format, along with the hard copy. Macintosh disks are also acceptable, but conversion costs will be assessed accordingly to AGT and a delay in processing may occur. Materials may alternatively be supplied to the editor via email at the address shown on inside front cover. Email submission is preferred. Illustrations must be original photographs, computer-generated digitized files (preferably saved as a .tif, .eps, or .bmp file), or black and white line drawings, professionally prepared. The cost of separating and printing color photographs or illustrations will be charged to the author. Photographs must be properly identified on the back, including the author’s name, title of article, and top direction. A ball point pen should not be used for labeling. The affixing of a typewritten label to the illustration or table will prevent damage.
Notation & References Authors’ titles must be accompanied by a position description of less than 15 words, which will be printed with the article. Textual citations to the referenced literature should be parenthetically noted by author’s surname followed by year of publication, and arranged chronologically and then alphabetically, as demonstrated in the following example: (Lese and Ledbetter, 1998; Reilly, 1998a; Morgan et al., 1999). In situations with more than two authors, the first author’s surname should be followed with et al. When references are made to more than one paper published in the same year by the same author, a lower case a, b, etc. should be appended to the date of publication and should be included in both textual citations and the reference list. References should be listed completely at the end of the paper in alphabetical order by surname of first author, and then by year of publication. When more than one publication appears with the same first author, listings will be alphabetized by the first varying co-author. Irrespective of the number of authors, et al. should not be used in the reference list. Journal titles should be abbreviated according to Index Medicus and book titles should be italicized. Use the following format for references: Journal Article Brothman AR, Zhu XL, Maxell T, Cui J, Derbler DA. Advances in the cytogenetics of prostate cancer. J Assoc Genet Technol. 1999;25(1):1-6. Book Chapter Barch MJ and Lawce HJ. The cell and cell division. In: Barch MJ, Knutsen T, Spurbeck JL (eds). The AGT Cytogenetics Laboratory Manual, 3rd ed. Philadelphia: Lippincott-Raven; 1997:1-18. Book Mark HFL. Medical Cytogenetics. New York: Marcel Dekker; 2000. All references should be complete. Accuracy is the responsibility of the authors. Only published articles and those in press may be included in the reference list. If necessary, unpublished data and submitted manuscripts should be cited parenthetically within the text.
Reprint Orders Reprints of articles can be purchased by authors at cost within two years after publication. On the order request, specify the journal’s volume and issue numbers, year of publication, page numbers, article title, author(s), and quantity requested. Include the contact name(s), address(es) and phone number(s) to be used for either shipping purposes or related questions. Payment should accompany the order. Checks must be made payable to AGT. Minimum order is 50 copies. Reprints are produced on 60# white offset paper, saddle-stitched (unless under four pages), and will appear exactly as they do in the journal. Price is based on article length, quantity ordered, and color requirements. Orders are not processed until payment is received. Once payment is received, allow four weeks for printing and shipping. Prices quoted include shipping by UPS ground; expedited shipping is available at an additional charge. Journal copies can be purchased by AGT members for $25/each, if copies are available. Please forward reprint orders or questions regarding price quotations to the AGT Executive Office (see inside front cover for address).
