Comprehensive follow-up of novel autism genetic discoveries  

Dr. Daly and his colleagues previously reported that genetic variation in the 16p11.2 chromosomal region is a major risk factor for autism. Daly and colleagues also uncovered more than 100 other rare genetic variations that appear to contribute to risk of autism. Daly proposes that comparison of the autism-associated variants from two sources would be a powerful way to identify autism-related genes. The group's original study analyzed samples from the Autism Genetic Resource Exchange, a collection of samples from families that have multiple children with autism, suggesting inherited variants. The Simons Foundation Autism Research Initiative (SFARI) Simplex Collection, in contrast, gathers samples from families with one autistic child, but unaffected siblings and parents, in order to identify spontaneous or de novo variants. Daly and colleagues plan to perform a meta-analysis of the two collections to look for and characterize common variants. Genes uncovered in both collections would probably be influential in the development of autism. Combining the data sets may also help pinpoint causative variants. For example, the researchers plan to determine the precise boundaries of copy number variants in order to learn which genes are affected. They also plan to sequence the variants using quick and inexpensive new methods so that many samples can be analyzed to reveal genetic variations in the region. Their results may suggest how a particular variant leads to autism, for example by disrupting gene expression. Project Status
