Duplication of chromosome 15 region mirrors autism

People with autism and those with duplications of the 15q11-13 chromosomal region share a distinctive pattern of gene expression in the brain, according to unpublished research presented Friday at the Dup15q Alliance Scientific Meeting in Sacramento, California.

Gene expression in neurons may not match number of copies

Neurons derived from individuals who carry extra copies of an autism-linked chromosomal region have gene expression patterns that are unexpectedly similar to those of neurons with deletions of the region. The unpublished findings were presented Thursday at the Dup15q Alliance Scientific Meeting in Sacramento, California.
