Body clock genes may set pace for sleep issues in autism

by  /  19 June 2015

People with autism are twice as likely to carry alterations in genes that regulate the circadian clock, or the body’s sleep-wake cycle as those without the disorder. The findings may help explain why most children with autism have trouble with sleep.

Online atlas unravels gene activity in diverse tissues

by  /  3 June 2015

A new resource reveals that gene expression varies more across tissues in one person than it does in the same tissue type among individuals. The findings, described 8 May in Science, indicate that the brain’s gene expression signature is unique.

Some sibling sets arrive at autism with different mutations

by  /  5 February 2015

Less than one-third of sibling pairs with autism who carry rare mutations in autism-linked genes share those mutations, according to the largest study yet to sequence whole genomes of people with the disorder. The study questions the assumption that autism’s risk factors run in families, but some experts are skeptical.

Paired genetic analysis may pare down list of autism genes

by  /  15 October 2014

Combining analysis of large deletions or duplications in the genome with sequences from protein-coding regions can identify new syndromes, as well as the mutations that cause those disorders, according to a report published 14 September in Nature Genetics.
