Close look at autism-linked region reveals complex biology

by  /  27 November 2013

Deletion and duplication of the 16p11.2 chromosomal region have opposite effects on brain size, but produce similar alterations in the brain’s processing of sound. Researchers reported these and other unpublished findings at the 2013 Society for Neuroscience annual meeting in San Diego, painting a complex picture of the region’s role in autism.
