Gene family mutation, autism linked

(Medical Xpress)—Harvard Medical School researchers at McLean Hospital have found that a gene family linked to autism, EphB, is essential for proper brain wiring during development. The findings suggest that the abnormal ...

Team discovers gene mutations linked to pancreatic cancer

Six genes contain mutations that may be passed down in families, substantially increasing a person's risk for pancreatic cancer. That's according to Mayo Clinic research published in the June 19 edition of the JAMA. However, ...

Like mountaineers, nerves need expert guidance to find their way

Similar to the dozens of Sherpas that guide hikers up treacherous Himalayan mountains to reach a summit, the nervous system relies on elaborate timing and location of guidance cues for neuronal axons—threadlike projections—to ...

'Smart' genes put us at risk of mental illness

(Medical Xpress)—Humans may be endowed with the ability to perform complex forms of learning, attention and function but the evolutionary process that led to this has put us at risk of mental illness.

Noncoding mutations contribute to autism risk

A whole-genome sequencing study of nearly 2,000 families has implicated mutations in 'promoter regions' of the genome—regions that precede the start of a gene—in autism. The study, which appears in the December 14 issue ...
