Researchers know that certain genes are linked to autism spectrum disorders — scientists have identified about 50 genes, and they estimate an additional 300 or more are also involved.
Pinpointing these genes is difficult, but it could be the key to understanding the cause of a disorder that affects 1 in every 68 children in the U.S., according to the Centers for Disease Control and Prevention. One child’s diagnosis of autism and the gene that contributed to it will likely be completely different than another child’s diagnosis and genetic influences. Now, a nationwide study will create the largest bank of autism genes in the country that researchers can contribute to and use in research.
Seattle Children’s Autism Center is helping launch the web-based registry with DNA analysis to accelerate autism research and speed discovery of treatments. The SPARK study, sponsored by the Simons Foundation Autism Research Initiative, encompasses 21 leading national research institutions doing autism research.
“When we work to identify genes that cause autism, we need a huge number of individuals diagnosed with autism because each genetic event that leads to autism is rare,” said Dr. Raphael Bernier, a researcher and clinical director of Seattle Children’s Autism Center. “This large registry allows us to identify genetic trends. Once we know which genes to focus on, we can look at more individualized treatments for the future.” Read full post »
