Experiments on an ultra-rare genetic mutation that causes neurodegeneration in children have helped uncover a new mechanism ...

A vanishingly rare genetic glitch in a single enzyme can erase a newborn’s brain cells in a matter of weeks, leaving doctors ...

From the time we are conceived and through old age, genetic mutations accumulate in all our tissues, eluding the body’s typically efficient DNA repair machinery and potentially affecting our health ...

A microscopic flaw in the brain’s cellular scaffolding can shape brain size for life.

Traditional biochemical methods of studying human gene mutations are often laborious and costly. Now bioengineers at the University of California San Diego have developed a new simple approach to ...

A man sits outside and holds a slim menthol cigarette between his fingers. Close-up with focus on the cigarette. The study provided a comprehensive examination of how lifestyle and environmental ...

Researchers identified a new genetic mutation that may allow some people to survive, even thrive, on three hours of sleep. The mutation is called SIK3-N783Y. Scientists said mice test subjects ...

Modern HIV medicine is based on a common genetic mutation. Now, researchers have traced where and when the mutation arose -- and how it protected our ancestors from ancient diseases. Modern HIV ...

A genetic mutation found in two human patients with schizophrenia also increased schizophrenia-related behaviors in mice with the same mutation, a rare finding of a direct genetic link to psychosis, ...
