Research into ancient DNA samples has discovered that those who carry genes for red hair also are have immune benefits — but are more likely to have celiac disease

As the body ages, cells naturally accumulate dozens of genetic mutations each year. New research from Boston Children's Hospital, published in Cell, finds that the brain's resident immune cells, microglia,

Researchers say a new AI system can identify disease-causing mutations and explain their biological effects, potentially changing how genetic disorders are diagnosed.

Some lucky people have rare genetic mutations that enable them to feel well-rested after just four hours of sleep, while the rest of us need around eight hours to function. Now, researchers have identified one of these mutations, named SIK3-N783Y, in a ...

SYNGAP1 encephalopathy is a rare genetic disorder for which there is no treatment. It causes epilepsy, intellectual disability, psychomotor delay and, frequently, autism. It arises from mutations in the SYNGAP1 gene,

Scientists studying animals at high altitudes discovered a previously unknown mechanism that is key for regulating myelin repair.

Decades ago, India’s tigers were on the brink of extinction. Slowly, their numbers have rebounded. But that ecological success has prompted a dire problem—and a race to save many of them from genetic collapse. In 2014 just four tigers remained in India ...

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 factors impact the rate of new genetic changes. These changes ...
