Fruit fly study uncovers functional significance of gene mutations associated with autism

About 1 in 44 children in the U.S. are diagnosed with autism spectrum disorder (ASD) by the age of 8, according to the 2018 Centers for Disease Control and Prevention surveillance. How a child's DNA contributes to the development of ASD has been more of a mystery. Recently, clinicians and scientists have looked more closely at new, or de novo, DNA changes, meaning they only are present in affected individuals but not in the parents. Researchers have seen that these changes could be responsible for about 30% of ASD. However, which de novo variants play a role in causing ASD remains unknown.
