New Information on Autism and Genetics

Research out of the George Washington University reveals another piece of the puzzle in a genetic developmental disorder that causes behavioral diseases such as autism.
"It tell us that in very early development, those with 22q11.2 deletion syndrome do not make enough cells in one case, and do not put the other cells in the right place. This occurs not because of some degenerative change, but because the mechanisms that make these cells and put them in the right place during the first step of development have gone awry due to mutation,"said LaMantia.
