Gray Lab Steven Gray, Ph.D. Assistant Professor
Gene Therapy Center
Carolina Institute for Developmental Disabilities Department of Ophthalmology
University of North Carolina at Chapel Hill
Dr. Steven Gray earned his Ph.D. in molecular biology from Vanderbilt University in 2006, after receiving a B.S. degree with honors from Auburn University.
He performed a
postdoctoral fellowship focusing on gene therapy in the laboratory of Jude Samulski at UNC. He is currently an assistant professor at UNC in the Department of Ophthalmology. He is also a member of the Gene Therapy Center and the Carolina Institute for Developmental Disabilities (CIDD).
Dr. Gray’s core expertise is in AAV gene therapy vector engineering, followed by
optimizing approaches to deliver a gene to the nervous system or eye. His major focus is in
AAV vector development to develop vectors tailored to serve specific clinical and research applications involving the nervous system or eye. These include the development of novel
AAV capsids amenable to widespread CNS gene transfer or specialized ocular gene
transfer. As AAV-based platform gene transfer technologies have been developed to achieve
global, efficient, and in some cases cell-type specific CNS gene delivery, his research focus has
also included preclinical studies to apply these reagents toward the development of treatments
for neurological diseases. Currently these include preclinical studies for Rett Syndrome, Giant Axonal Neuropathy (GAN), Tay-Sachs, Krabbe, AGU, and Batten Disease, and have expanded into human clinical studies to test a gene therapy approach for GAN.
Dr. Gray has published over 50 peer-reviewed papers in journals such as New England
Journal of Medicine, Molecular Therapy, Nature Biotechnology, Gene Therapy, and The Proceedings
of the National Academy of Sciences. He also has 3 pending patents. His research is funded by the

Kennedy Lab Andrew John Kennedy, Ph.D. Assistant Professor Bates College
E-mail: akennedy@bates.edu Dr. Kennedy’s research goal is to understand the chemical mechanisms that encode and maintain long-term memory, and
how these mechanisms have become dysregulated in intellectual
disability. His laboratory investigates how learning imprints information onto the epigenome of participating neurons, and how these biochemical pathways can be manipulated to enhance cognition in cases of intellectual disability. Currently, the lab studies the basic neurobiology
underlying Pitt-Hopkins Syndrome, an ultra-rare intellectual disorder on the autism spectrum
caused by the haploinsufficiency of transcription factor 4 (Tcf4). Additionally, the lab designs,
synthesizes, and evaluates neuroepigenetic therapeutics that alter histone acetylation or DNA methylation of plasticity-related genes to improve learning and memory in disorders marked by impaired memory function.
Maher Lab Brady J. Maher Ph.D. Lead Investigator
Lieber Institute for Brain Development Assistant Professor
Department of Psychiatry and Behavioral Sciences; Department of Neuroscience Johns Hopkins School of Medicine E-mail: brady.maher@libd.org
Dr. Maher's lab is interested in understanding the cellular and circuit pathophysiology that underlies
neurodevelopmental and psychiatric disorders. Recent progress in clinical genetics has led to the
identification of genetic variation and genes that are associated with these disorders. However, information about the function of many of these genes during neurodevelopment and in the adult brain is lacking. His group focuses on trying to understand the function of these risk genes by manipulating their expression level in utero during the peak of cortical development. His lab then use a variety of
approaches and technologies to identify resulting phenotypes and molecular mechanisms including cell and molecular biology, optogenetics, imaging, and electrophysiology.

Powell Lab Craig M. Powell, MD, PhD, FAAN, FANA
Ed and Sue Rose Distinguished Professor in Neurology Associate Professor
Section Head of Neurodevelopmental Disorders Department of Neurology & Neurotherapeutics Department of Psychiatry
Neuroscience Graduate Program University of Texas Southwestern Medical Center Dr. Powell is an Associate Professor with Tenure of Neurology and Psychiatry at UT Southwestern Medical Center who offers expertise in preclinical models of autism and intellectual disability and more recently in clinical studies of these conditions. Dr. Powell’s work characterizing genetic models of autism and intellectual disability based on Neuroligin 3,
Neuroligin 1, Neurexin 1, PTEN, Shank3 and other genetic causes has provided novel insights into the pathophysiology of autism and novel therapeutic targets for autism and intellectual disability. Indeed, his studies have led to the initiation of an NIH-funded clinical study of an
FDA approved drug for a genetic cause of autism. Dr. Powell’s recent inroads into translating preclinical treatments into actual patients provides a road map for future studies using animal models of Pitt Hopkins Syndrome to identify novel biomarkers and treatments for patients and their families.

Chair of Molecular Biology Department of Gene Technology Tallinn University of Technology Akadeemia tee 15
19086 Tallinn, Estonia
E-mail: tonis.timmusk@ttu.ee Telephone: +372 620 4444, Fax: Phone: +372 620 4400 Dr. Timmusk is a molecular neurobiologist with research interests in gene regulation and signaling in the nervous system. In addition, his research investigates mechanisms of nervous system diseases, such as the neurodegenerative disorders Huntington’s and Parkinson’s diseases and more recently also schizophrenia and mental retardation. Studies of Dr. Timmusk’s research group have contributed to the understanding of the function and signaling of nerve
growth factor (NGF) and glial-cell derived neurotrophic factor (GDNF) family ligands and receptors and to activity-dependent transcriptional mechanisms that underlie nervous system function in health and disease. His laboratory uses wide array of methods of molecular and cell
biology, biochemistry, primary neuronal cultures and animal models, including transgenic mice. Recently his lab has started to study the function and mechanism of action of the bHLH transcription factor TCF4, the gene of which is mutated in Pitt-Hopkins syndrome (PTHS). Mari Sepp, Ph.D. Research scientist, Timmusk lab E-mail: mari.sepp@ttu.ee
My research interests focus on transcriptional dysregulation in
neurodevelopmental and neurodegenerative diseases, and activitydependent gene regulation in the nervous system. I have
investigated the functions of transcription factor 4 (TCF4) in health and disease by characterizing human TCF4 gene structure
and TCF4 expression at mRNA and protein level, studying the functional characteristics and
regulation of alternative TCF4 isoforms in non-neural cells and neurons, and determining the
impact of Pitt-Hopkins syndrome and non-syndromic intellectual disability associated mutations on TCF4 functions. I am currently studying the mechanisms underlying
neuronal activity-dependent regulation of TCF4 as well as its target genes in neurons in order to better understand its role in cognitive diseases and in the functioning of the nervous system
in general. I believe that a more precise understanding of the mode of how TCF4 is regulated
in neurons opens up opportunities for target identification for possible therapeutic intervention in Pitt-Hopkins syndrome.
Student Scientists Sofia Pauca
High School Student Junior Scientist Milligan Lab, Wake Forest University Email: sofia.tcf4@gmail.com I am a high school senior who is extremely interested in neurobiology research. During my freshman and sophomore years, I worked as a volunteer researcher in the Milligan Lab, Department of Neuroscience, Wake Forest University. My 10 year old brother
Victor has Pitt Hopkins, and because of him I have been inspired to conduct research concerning his syndrome. During this research, we performed a histological and
immunohistological study of the transgenic TCF4 and wild type mouse brain. In middle
school, I also conducted a three year research project on autism (specifically Fragile X) in drosophila melanogaster with Dr. Bill Connor from WFU. Two of these years, I received first place in Biology in the North Carolina State Science Fair. This past summer, I was selected as
a Summer Intern at the National Institutes of Environmental Health Sciences, Raleigh, NC, in Dr. Patricia Jensen's Developmental Neurobiology Lab. My research focused on deciphering
the role of norepinephrine in neocortical development. I am currently continuing this research throughout the year, and have been invited back as an intern for next summer. I hope to do
similar research in the future, and eventually go into this field as a career. Thank you to everyone who has helped me on my scientific journey so far, especially my family. Bennett Gould Student Scientist High school student, senior Alexander Lab, Wake Forest University Email: goulbp16@wfu.edu
I am a high school student studying Pitt-Hopkins Syndrome. I have been working in the Alexander lab at WFU for the past 6 months; Dr. Alexander runs a biochemistry lab focused on aminoacyl TRNA synthetases (AARS), but one of the tools she uses is molecular dynamics. I studied the effects of a single missense mutation (A587P) generated in TCF4 on conformational change and flexibility of the TCF4:NEUROD2 pseudo homodimer. Molecular dynamics simulations were run for 85 ns and in triplicate. Moving forward, I hope to continue work on this project by using graphic processing units (GPUs) to extend the timescale for the simulations to 10 ÉĽs. I would like to thank Dr. Mari Sepp for sending me the PDB of the pseudo homodimer that is originally from Dr. T. Ellenberger. Moreover, this would not have been possible without Dr. Rebecca Alexander, Lindsay Macnamara (PhD candidate), Dr. Cho, and the Pauca family.

Dr. Norbert Wiech is the founder of Lysomics, LLC. and Chromatin Therapeutics, LLC to develop treatments for rare diseases based on epigenetic targeted pharmacology.
His
undergraduate and graduate degrees were obtained at the University of Notre Dame and doctorate in biochemistry from Tulane University. After graduation he was appointed as a corporate fellow at the Harvard School of Public Health which was pioneering nutritional
studies related to cardiovascular diseases. He has more than forty years of experience in the pharmaceutical industry as a researcher, manager and an executive. He participated in the pre-
clinical product development and in the clinical development group for several “first of a class� of treatments.
He founded his first company in 1992 and shortly thereafter in 1994 a second company
Pharmaceutics International to provide contract pharmaceutical product development services and served as its CEO until 1998. In 1995, he became the CEO of the orphan drug company,
Ucyclyd Pharma. Under his leadership, Ucyclyd obtained FDA approval for the orphan drug
product Buphenyl, a brand of sodium phenylbutyrate for the treatment of the rare disease urea cycle disorders.
After the sale of Ucyclyd, he was asked to participate in a range of management roles to
advance the discovery and development of histone deacetylase inhibitors in privately held biopharmaceutical operations. As an adjunct at Notre Dame, he funded the start-up of the
HDAC program to investigate the potential of these novel drugs to treat neurological disorders which led to start of a clinical trial to treat Niemann Pick Type C. He teaches and mentors in a
program to introduce undergraduate science majors to entrepreneurship in particular for Orphan Drugs.
Abstracts Title: The Case for HDAC Inhibition
Andrew Kennedy, PhD Bates College
Targeting histone deacetylases (HDACs) to enhance synaptic plasticity and broadly improve cognition has been established in disease and disorder model systems, as well as in neurotypical mice. Here, we
demonstrate that targeting HDACs using small molecule inhibitors may be a viable path to improving
cognition in Pitt-Hopkins Syndrome, by demonstrating their efficacy to improve learning and memory
in a Tcf4 (+/-) mouse model. Using next generation sequencing, we have identified downstream targets of HDAC inhibition in the hippocampus of Tcf4 (+/-) mice. We have also developed a novel
therapeutic that specifically targets HDAC2, an isoenzyme in the HDAC family that has been
demonstrated to be a negative regulator of learning and memory, and we have begun a systematic
evaluation of its long-term efficacy. These data suggest HDAC inhibition is a viable clinical option for
Pitt-Hopkins Syndrome.
Lay Talk: The Genetics of Pitt-Hopkins Syndrome
Pitt-Hopkins Syndrome is caused by a mutation in or a deletion of Transcription Factor 4 (Tcf4). But what does Tcf4 do in the body and in the mind? And why does the loss of Tcf4 function cause Pitt-
Hopkins? We’ll be discussing what we know about the genetics of Pitt-Hopkins, as well as the
approaches Pitt-Hopkins researchers are taking to understand what the loss ofTcf4 means for the brain and how it might be treated.
Title: Regulation of TCF4 transcriptional activity in neurons Mari Sepp and TĂľnis Timmusk
Department of Gene Technology, Tallinn University of Technology
Calcium-dependent gene expression in neurons is one of the mechanisms by which neuronal plasticity, enabling higher organisms to learn from and adapt to environment, is achieved. We
have identified TCF4 as a neuronal activity and calcium-dependent transcriptional activator in
neurons, providing insights into the mechanisms that underlie Pitt-Hopkins syndrome
(PTHS), a complex disorder caused by mutations in one of the TCF4 alleles and characterized
by severe intellectual disability (ID) and autistic-like behaviour. We and others have recently
demonstrated that, in addition to PTHS, mutations in TCF4 gene give rise to milder, nonsyndromic ID. The position of the mutation in TCF4, a gene with complex organization and
multiple transcription initiation sites, is relevant to the phenotype, supporting the notion that precise regulation of TCF4 expression levels and the correct dose of its alternative isoforms are critical for correct brain development and function. Notably, our results from fruitflies show that proper expression of TCF4 is crucial for survival even after development has been completed.
To understand the role of TCF4 in the neuronal activity-regulated transcription comprehensive
knowledge about its signal-dependent regulation mode, functionally important protein regions, and target genes is required. Therefore, in the current study we aimed (1) to further delineate the steps that lead from increase in cellular calcium and/or cAMP to activation of TCF4-
mediated transcription in neurons, (2) to analyze the functional impact of newly identified TCF4 mutations/variations associated with PTHS, mild to moderate ID and schizophrenia,
(3) and to identify neuronal activity-regulated TCF4 target genes using whole transcriptome analysis.
Title: Relation between the location of TCF4 mutations and the severity of intellectual disability
Mari Sepp and TĂľnis Timmusk
Department of Gene Technology, Tallinn University of Technology
TCF4 gene codes for numerous TCF4 protein isoforms of different length. All isoforms contain the sequences coded by downstream part of the TCF4 gene while only the longer
isoforms contain sequences coded by the upstream part of the gene. Mutations in one of the
two gene copies of TCF4 are usually associated with Pitt-Hopkins syndrome (PTHS) that features severe intellectual disability. However, some TCF4 mutations have also been linked to
milder non-syndromic intellectual disability. We propose that rather than the mutation type
(e.g deletion vs. point mutation) the position of the mutation in TCF4 gene is relevant to the disease severity. PTHS-associated mutations are located in the downstream part of the gene and affect all TCF4 isoforms. Milder phenotypes are elicited by mutations that locate to the
upstream part of the TCF4 gene and leave shorter TCF4 isoforms intact, or by certain small
mutations in regions not affecting the important functional domains of TCF4 protein. Altogether, it is possible that a continuum of phenotypes from mild intellectual disability to
PTHS are caused by different TCF4 mutations with the outcome depending on the number of remaining intact TCF4 isoforms produced from the mutation-carrying TCF4 gene copy.
Title: Virtual Collaborations for Developing Treatments on a Shoestring
Sean Ekins, PhD
Collaborations Pharmaceuticals, Inc., Hereditary Neuropathy Foundation
Phoenix Nest (http://www.phoenixnestbiotech.com/) was co-founded with a rare disease parent (Jill Wood 1) and is working on treatments for Sanfilippo syndrome (MPS III), a
devastating neurodegenerative lysosomal storage disorder of childhood. In the space of 4 years, we have built up collaborations with leading academics and industry and submitted multiple NIH small business technology transfer (STTR) grant proposals. We completed our first phase I NIH NINDS STTR in 2015 grant to fund development of an enzyme replacement therapy with our academic collaborator (LA BioMed) for MPS IIID (an ultra-rare disease). More
recently we obtained phase II funding for this project such that we have been awarded ~$1.75M total. In addition, we have recently obtained a second Phase I grant ($250K) to
develop a stem cell/ gene therapy treatment for MPS IIIB. Our focus for return on investment
is the rare pediatric disease priority review voucher from the FDA 2. I will highlight our evolving, lean company strategy, which enables a small virtual team to coordinate and leverage
the academic research resources that have been accumulated. I will summarize our collaborative strategy and efforts to partner with global groups to pursue additional treatments for MPS III
e.g. gene therapy, chaperone therapy for MPS IIIC. I have recently founded a second company (Collaborations Pharmaceuticals, Inc. (http://www.collaborationspharma.com/) to address other rare and neglected diseases and was recently awarded an STTR with Rutgers University
to work on treatments for tuberculosis ($150K) 3. I am currently working on projects with
several university collaborators and licensing compounds and technologies. At a bare minimum, other rare and neglected diseases could leverage this approach 4. To do this, they require at least
one scientist with whom you can submit grants and papers, and ultimately, licensing what comes out of the work will be just as important to aid in funding further development. We
would encourage other scientists to collaborate with small companies like these to further the
research on their diseases. From my experiences, this has lead to creation of jobs, funding for academic labs and moving potential treatments closer to the clinic. 1.

Pitt Hopkins Syndrome (PTHS) is a rare autism spectrum disorder that results from mutation in Transcription Factor 4 (TCF4) and for which no specific treatment is known. My
presentation will focus on recent work in my lab aimed at developing novel treatments for PTHS. I will focus on our recent identification of SCN10a, a voltage-gated sodium channel, as
a potential therapeutic target. Several pharmaceutical companies have developed compounds that specifically target SCN10a for the treatment of pain, and one of these compounds has passed Phase I, but failed in Phase II because it did not reduce the sensation of pain. We are
now testing this compound for efficacy at rescuing behavioral deficits in our PTHS mouse model and I will discuss the results of these studies as well as our plans to repurpose this
compound for treatment in PTHS. In addition, I will discuss our research program aimed at using patient derived induced pluripotent stem cells (iPSCs) and human neurons to identify novel therapeutic targets and to translate our findings from rodent models into a human model.

Pitt-Hopkins Syndrome (PTHS) is a monogenic neurodevelopmental disorder caused by autosomal dominant mutation in TCF4. The underlying pathophysiology generated by haploinsufficiency of TCF4 protein remains unclear. Previous work on prefrontal layer 2/3
pyramidal neurons found an abnormal membrane firing property in TCF4+/tr mice, which model PTHS. This deficit is partly due to ectopic expression of two ion channels including
SCN10a and KCNQ1 in excitatory neurons. Multiple studies have identified an imbalance of excitatory and inhibitory synaptic transmission in several different animal models of psychiatric
disorders. Therefore, we hypothesize that the decreased excitability observed in prefrontal
neurons in the PTHS mouse will negatively impact network activity levels and lead to a decrease in spontaneous excitatory and inhibitory synaptic transmission. To test this hypothesis,
we characterized the spontaneous synaptic transmission onto prefrontal layer 2/3 pyramidal
cells by whole-cell patch clamp in TCF4+/tr and wildtype littermates. We found both spontaneous excitatory postsynaptic current (sEPSC) and inhibitory postsynaptic current (sIPSC) frequencies are reduced in TCF4+/tr mice compared to controls. However, we saw no
effect on the frequency or amplitude of miniature EPSCs or IPSCs that were measured in the
presence of TTX. This differential effect on spontaneous versus miniature synaptic transmission is indicative an overall decrease in network activity. In addition, we characterized parvalbumin (PV) positive fast spiking interneurons (FS) in our PTHS mouse model and observed no changes in the intrinsic excitability or the frequency and amplitude of sEPSCs
onto FS cells. However, the sIPSC frequency was significantly lower in TCF4+/tr mice. Together, our data suggests that the prefrontal cortex of our PTHS mouse shows a general deficit in network activity that may contribute to the pathophysiology of PTHS.
Title: Gene Therapy for Central Nervous System Diseases

Gene therapy for central nervous system (CNS) disorders has seen a recent resurgence with the
discovery of adeno-associated virus (AAV) vectors that are capable of crossing the blood-brain barrier (BBB), such as AAV9. The Gray lab has been focused on examining the translational
potential of AAV9 to treat inherited CNS disorders. Initial studies demonstrated that AAV9 can achieve dose-dependent, widespread gene transfer to neurons and astrocytes in mice as well
as in non-human primates. However, several details hampered the clinical translation of this approach including: high vector doses (manufacturing burden), presence of natural anti-AAV
neutralizing antibodies in some individuals, and high peripheral organ gene transfer potentially causing gene-dependent toxicity. Nonetheless, at least 2 clinical trials have been initiated using
AAV9 vectors injected intravenously, for Spinal Muscular Atrophy and Mucopolysaccharidosis
Type IIIA. In lieu of an intravenous route of administration, intrathecal administration of AAV9 also leads to broad CNS gene transfer in mice, pigs, and non-human primates, but overcomes some of the limitations associated with intravenous administration.
Using AAV9-mediated gene transfer as a platform approach to treat an inherited CNS
disease, we have initiated preclinical studies for Giant Axonal Neuropathy (GAN), Batten
Disease, Aspartylglucosaminuria, Tay-Sachs disease, Krabbe disease, and Rett syndrome. Based on encouraging preclinical data showing reduce pathology and increased rotarod function in GAN mice, along with favorable safety data, a clinical trial was initiated in May 2015 at the
NIH Clinical Center to test intrathecal administration of scAAV9/JeT-GAN in patients with
GAN. Using the same approach, encouraging preclinical data has been generated for each of
the other diseases with efforts underway to translate the treatments for Krabbe disease and
Batten disease to human trials. A pilot study to assess the feasibility of gene therapy for PittHopkins is underway.
Title: Convergent evidence for hippocampal NMDA receptor hyperfunction in PTHS Ben Philpot, PhD
Associate Director, UNC Neuroscience Center Department of Cell Biology & Physiology, University of North Carolina, Chapel Hill
There are no treatments for the core symptoms of PTHS, which result from haploinsufficiency of the transcription factor, TCF4. The hippocampus, an important brain region for learning and memory, expresses particularly high levels of TCF4 and has reduced volume in PTHS
individuals, suggesting that dysregulation in this region dictates many PTHS core phenotypes. Little is known about the synaptic and cellular hippocampal functions affected by TCF4 loss, which has impeded the rational development of PTHS therapeutics, especially those that could overcome the debilitating learning difficulties. Our lab has generated multiple mouse models
of PTHS, including a “first of its kind� model carrying the highly prevalent, pathogenic human R580W mutation within the basic helix-loop-helix region of TCF4 (mouse Tcf4R579W). Our
data from these models indicate that loss of TCF4 function leads to weight loss, low anxiety, hyperactivity, and poor spatial memory (a hippocampal-dependent task). Our data, from four
separate PTHS mouse models, also show that TCF4 loss inappropriately enhances the induction of hippocampal long-term potentiation (LTP), likely due to selectively increasing
synaptic NMDA receptor (NMDAR) currents, while other synaptic measures appear normal. Our observations are consistent with anecdotal reports that NMDAR antagonists (e.g. Amantadine)
provide
therapeutic
benefits
to
PTHS
individuals.
Title: Large-scale untargeted metabolomics profiling in Pitt-Hopkins syndrome uncovers phenotypic-associated amino acid and lipid abnormalities Joseph T. Alaimo and Sarah H. Elsea
Department of Molecular and Human Genetics Baylor College of Medicine
Transcription factor 4 (TCF4) encodes a helix-loop-helix transcription factor that, when
haploinsufficient, results in the neurodevelopmental disorder Pitt-Hopkins syndrome (PTHS). PTHS is characterized by severe intellectual disability, absent speech, seizures, breathing
abnormalities, behavioral problems, and delayed motor milestones in which more than half fail
to walk independently. In addition, natural variation at this locus is associated with the complex
disease schizophrenia. The phenotypic spectrum associated with TCF4 variation suggests a unique role for the protein in pathways mitigating neurodevelopment and cognitive function;
therefore, we sought to undercover functional pathways regulated by TCF4 through the application of a small molecule metabolomics screen. We examined plasma samples of 13 individuals with a molecularly confirmed diagnosis of PTHS that were predominately male and
ranged in age from 1.5 to 20 years. Our cohort had a history of global developmental delay, absent or sparse speech, seizures and sleep anomalies. Metabolomic profiles from this cohort were significantly enriched for alterations in lipid and amino acid associated pathways. All
individuals displayed abnormal lipid profiles, but consistent alterations were observed in fatty
acid and phospholipid metabolism. We identified elevated oleamide levels, an endogenously
metabolized fatty acid amide associated with sleep problems, a phenotypic feature of our cohort. In addition, abnormalities across palmitic acid metabolism and utilization were
identified, including elevated palmitic amide a known marker for schizophrenia. Amino acid abnormities were observed across 12 of 13 samples with consistent alterations found in pathways associated with oxidative stress and mitochondria function, such as methionine
sulfoxide and N-acetylaspartate. Interestingly, 3 individuals within our cohort displayed alterations in carnitine metabolism suggesting carnitine biosynthesis defects and were recommended for further clinical testing. Taken together, the application of metabolic profiling in individuals with PTHS suggests that TCF4 plays a functional role in small molecule
pathways that may contribute to the phenotypic features of the disorder. Future studies
discerning the cellular defects associated with these metabolic alterations will likely present new opportunities for therapeutic interventions in PTHS.

Available clinical studies describe individuals with Pitt-Hopkins Syndrome (PTHS) as exhibiting some of the core symptoms of Autism Spectrum Disorder (ASD), including
difficulties in verbal and nonverbal communication, sensory sensitivity, and social interaction difficulties. Significant developmental delays, including motor delays, and intellectual disability are also reported in individuals with PTHS. The current studies focused on obtaining
demographic information as well as standardized caregiver-report measures of development,
behavior, and ASD symptoms to clarify and characterize the presence of ASD symptoms in
this population, with particular emphasis on the social, communication, adaptive, developmental, and repetitive behaviors of individuals with PTHS. Information regarding
ASD symptoms and patterns of behavior within genetic syndromes such as PTHS may be helpful in characterizing a broader ASD phenotype. Further, a better understanding of social
communication and behavioral difficulties in individuals with known genetic differences and developmental delays may help guide more informed recommendations for intervention.
Parent/caregiver participants were recruited through the Pitt Hopkins Research Foundation and completed questionnaires over the telephone and by mail, including a detailed
demographic and background questionnaire, the Modified Checklist for Autism in ToddlersRevised (M-CHAT-R), Communication and Symbolic Behavior Scales-Infant Toddler Checklist (CSBS-ITC), Repetitive Behavior Questionnaire (RBQ), Short Sensory Profile-2 (SSP-2), and Vineland Adaptive Behavior Scales- II. Additional measures of behavioral
difficulties were also obtained. To date, 29 families have completed measures for this study
with children with PTHS ranging in age from 11 months to 19 years old, with initial data indicating developmental delays across skill areas. Over half of respondents reported tantrums
in their children but aggression towards others was much less frequent. Nearly all individuals with PTHS were engaged in intervention services including special education support,
speech/language, physical, and/or occupational therapies. On rating scales, individuals with PTHS were described as exhibiting delays in early emerging social-communication skills on the
CSBS-ITC and the presence of significant ASD “red flags� on a brief screening tool developed for very young children. On the RBQ, a tool that has demonstrated good validity in measuring
repetitive behaviors in several genetic syndromes as well as ASD, individuals with PTHS received elevated scores for overall repetitive behaviors and in particular, the presence of clinically significant stereotyped behaviors. A range of sensory differences in comparison to
children without developmental delays were also endorsed by caregivers on the SSP-2. Future directions will include more specific, direct observations of skills and behaviors in individuals
with PTHS utilizing standardized assessments specific to cognitive skills and ASD symptoms to obtain more detailed information.
