the Brain & Behavior Research Foundation for Autism Functional Genomics
Combining CRISPR and Human Neurons to Dissect Autism Genetics
Neville Sanjana, PhD, Core Faculty Member at the New York Genome Center, Assistant Professor of Biology, New York University, and Assistant Professor of Neuroscience and Physiology at NYU School of Medicine, is the recipient of the Brain & Behavior Research Foundation’s Young Investigator Award. This grant will support the Sanjana Lab’s research on single-cell functional genomics of mutations implicated in severe forms of autism spectrum disorder (ASD) and intellectual disability (ID).
In 2016, the Centers for Disease Control estimated that 1 in 68 children were diagnosed with ASD, a disorder of the nervous system whose causes and treatment remain elusive in many cases, despite its prevalence. In order to better understand the mechanisms underlying the mutations found in autism, Dr. Sanjana and his team will develop novel gene editing methods for high-throughput, genetically-based subtype identification of de novo ASD variants. De novo mutations are alterations in the DNA of a child that are not found in the parents. They can arise from mutations in the germ line cells (sperm or egg) of the parents. Emerging evidence from whole-exome and whole-genome sequencing studies in individuals with ASD and ID highlights a prominent role of de novo mutations. One goal of Dr. Sanjana’s research is to rapidly deduce which mutations alter cortical neuron function and whether shared mechanisms exist between different mutations implicated in ASD and ID.
“We are pleased to support Neville Sanjana’s promising autism research,” said Dr. Jeffrey Borenstein, President & CEO of the Brain & Behavior Research Foundation. “The Young Investigator grants are part of the continued investment BBRF makes in brilliant young scientists conducting neurobiological research that is most likely to lead to breakthroughs in understanding and treating mental illness.”
“We are very grateful for this support from the Brain & Behavior Research Foundation and are excited to develop CRISPR-based screens to speed progress in understanding the genetics of ASD,” said Dr. Sanjana. His research utilizes high-throughput methods to identify changes in gene expression after ASD-associated de novo mutations are introduced into human cells. After designing and introducing a pooled CRISPR library into human pluripotent stem calls, Dr. Sanjana then differentiates human cortical neurons and analyzes changes in neuronal gene expression for each mutation.
Progress in ASD research has been slow, as mouse models of ASD mutations have been met with limited success. An important difference in Dr. Sanjana’s approach is the use of human cortical neurons – in effect, ‘human neurons in a dish.’ Dr. Sanjana explained, “Neurons are something that obviously we can’t get directly from human patients. However, gene editing in stem cells and differentiating the stem cells into cortical neurons gives us a powerful platform for understanding what is going wrong in neurons with autism-associated mutations.”
As the cost of sequencing a human genome continues to fall, physicians are better able to diagnose severe forms of autism and intellectual disability at early stages but treatment options are often limited. The Sanjana Lab’s research is focused on addressing this unmet need: to understand the genetic mechanisms underlying ASD in order to rationally design effective therapies.
