Molecular mechanisms: Gene marker may alter autism brains

by  /  15 April 2014

In the brains of people with autism, certain genes are suppressed by a chemical tag that increases binding to MeCP2, the protein implicated in Rett syndrome. The findings were published 21 January in Translational Psychiatry.

Emerging importance of chromatin in autism risk

by ,  /  18 March 2014

Sequencing studies over the past few years have made a dramatic and unexpected discovery: Many of the mutations in individuals with autism are in genes that regulate chromatin, which helps package DNA in the cell nucleus, say Gerald Crabtree and Aryaman Shalizi.
