CHICAGO (Reuters) - Scientists have characterized the role of thousands of mutations in the BRCA2 cancer gene, findings that may help reassure worried patients about their cancer risk or guide doctors ...

Genetic changes that create ever-expanding numbers of identical sperm cells are more widespread than previously thought, according to a new study led by researchers at Harvard Medical School. The team ...

While men may be able to have children much later than women, doing so could come with an increased risk of inherited disease for their children. Researchers from the Wellcome Sanger Institute have ...

In a step toward treating mitochondrial diseases, researchers in the Netherlands have successfully edited harmful mutations in mitochondrial DNA using a genetic tool known as a base editor. The ...

Scientists at the Ontario Institute for Cancer Research (OICR) have uncovered one way tobacco smoking causes cancer and makes it harder to treat by undermining the body's anti-cancer safeguards. Their ...

Artificial intelligence firm Google DeepMind has adapted its AlphaFold system for predicting protein structure to assess whether a huge number of simple mutations are harmful. The adapted system, ...

Between any two people, there are likely to be at least 10 million differences in the genetic sequence that makes up their DNA. Most of these differences don't alter the way cells behave or cause ...

Groundbreaking research shows that as men age, harmful genetic mutations in sperm become more common—not just from random chance, but because some are naturally favored. Advanced sequencing revealed ...

While most known types of DNA damage are fixed by our cells’ in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

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 ...
