Autism Research

Autism Research lectures bring together scientists and scholars to discuss diverse and important topics related to autism. The lectures are open to the public and are held at the Gerald D. Fischbach Auditorium at the Simons Foundation headquarters in New York City. Tea is served prior to each lecture.

 
On 22 March 2017, Stephan Sanders presented an update on the current state of genetics research in autism, highlighting some of the key findings that remain to be discovered, and discussing how these findings could ultimately benefit individuals with autism and their families.

His talk was part of the Simons Foundation Autism Research lecture series.

About the Lecture

It has been known that autism spectrum disorder is primarily caused by genetic factors for several decades. The past 10 years have seen great progress in finding some of the genes responsible and in building a map of what other types of genetic variants may contribute. These findings have been used both to provide insight into the biology of autism and, in the clinic, to identify individuals with specific genetic variants.

In this lecture, Stephan Sanders presented an update on the current state of genetics research in autism, highlight some of the key findings that remain to be discovered, and discussing how these findings could ultimately benefit individuals with autism and their families.

About the Speaker

Stephan Sanders trained as a pediatric physiscian in the United Kingdom before pursuing a research career in genomics and bioinformatics. His work has helped characterize the role of de novo mutations in the etiology of autism and identified multiple autism risk loci, including duplications of the 7q11.23 Williams syndrome region (Sanders et al., Neuron, 2011) and mutations in the sodium channel gene SCN2A (Sanders et al., Nature, 2012). His work on the integration of copy number variation and exome data across multiple autism cohorts recently identified 71 autism risk loci (Sanders et al., Neuron, 2015). In addition, he worked as part of a group that integrated spatiotemporal gene expression data from the human brain with these autism-associated genes (Willsey et al., Cell, 2013). This approach has implicated deep-layer glutamatergic neurons in the frontal cortex during mid-fetal development in the causation of autism. His lab has three main research aims: 1) Understanding the genetic basis of childhood neurodevelopmental conditions, in particular autism; 2) Understanding how these genetic factors lead to the conditions; and 3) Understanding the mechanism that leads to the male bias in autism diagnosis, in particular through identifying the biological basis of the female protective effect.

Past Lectures

On the road to precision health: Brain-based biomarkers in autism spectrum disorder

Shafali Spurling Jeste, M.D.Associate Professor in Psychiatry, Neurology and Pediatrics, University of California, Los Angeles
Director, Developmental Neurophysiology Lab, Center for Autism Research and Treatment, University of California, Los Angeles

On 7 February 2018, Shafali Spurling Jeste provided a topical overview of the current state of research in autism biomarkers. She shared data from studies of autism biomarkers in three key areas: early risk prediction (studies of high-risk infants), heterogeneity within the autism spectrum and genetically defined subgroups within autism. Finally, she discussed the challenges around clinical trial design and development and considered how more objective measures of brain function can improve clinical trials.

Arousal, emotion regulation and challenging behaviors: Insights from the Autism Inpatient Collection

Matthew Siegel, M.D.Associate Professor of Psychiatry and Pediatrics, Tufts University
Vice President, Medical Affairs, Developmental Disorders Service, Maine Behavioral Healthcare

On 24 January 2018, Matthew Siegel drew upon a new resource, the Autism Inpatient Collection data set, to offer preliminary insights into the relationships between physiologic arousal, emotion dysregulation and the occurrence of challenging behaviors. Such behaviors may represent an attempt to modulate physiologic arousal in minimally verbal individuals with autism spectrum disorders.

Autism genetics: Searching for coherence

Daniel Geschwind, M.D., Ph.D.Professor, University of California, Los Angeles

On 28 November 2017, Daniel Geschwind discussed his group’s use of RNA sequencing, chromatin structure and gene networks to help develop an understanding of potential convergent mechanisms in autism spectrum disorders.
