Researchers have identified a direct link between deletion in two genes and specific brain and body traits. Both genes are in the 16p11.2 area of chromosome 16. Deletions in this region are associated with ASD and other developmental disorders.
Researchers have performed an MRI study of people with a common form of genetic autism. They discovered those with abnormalities on 16p11.2 had structural abnormalities with the corpus callosum and white matter volume.
