Scientists have created a complete map showing how hundreds of possible mutations in a key cancer gene influence tumor growth. The study focused on CTNNB1, a gene that produces the protein β-catenin, ...

UCLA Health researchers have created a comprehensive map showing how eight different genetic mutations associated with autism ...

Almost 1,500 genes have been implicated in intellectual disabilities; yet for most people with such disabilities, genetic causes remain unknown. Perhaps this is in part because geneticists have been ...

Despite progress in defining functional elements of noncoding DNA, it is still not fully understood. Researchers, using an experiment that elucidated the function of tens of thousands of noncoding ...

Human semen not only accumulates genetic mutations with age; as the percentage of sperm carrying potentially serious mutations increases, so does the risk of developing diseases in offspring. This is ...

Tiny genetic alterations could help the bird flu virus enter cells in the upper respiratory tract, the C.D.C. said. But there is no sign that mutations are widespread in nature. By Benjamin Mueller ...
