Gene screen reveals altered chemical tags in autism brains

by  /  14 October 2013

One of the largest genome-wide screens of methyl tags in postmortem brains has found that people with autism have three unique regions of methylation — chemical modifications that affect gene expression. The results were reported 3 September in Molecular Psychiatry.

Gene expression in neurons may not match number of copies

by  /  23 September 2013

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 The unpublished findings were presented Thursday at the Dup15q Alliance Scientific Meeting in Sacramento, California.
