Genetic mutations and DNA changes can lead to several health conditions, ranging from mild to life-threatening disorders.

For decades, the dream of fixing harmful mutations in mitochondrial DNA felt out of reach. Scientists have long known these mutations cause serious diseases that pass down only through mothers. They ...

From decoding hidden genetic mutations to testing novel treatments, scientists are making real progress against rare inherited eye diseases. These breakthroughs could mean earlier diagnoses, targeted ...

Scientists have corrected gene mutations in mice causing an ultra-rare disease by editing DNA directly in the brain with a single injection, a feat with profound implications for patients with ...

Researchers at the Mayo Clinic and Goodfire, a San Francisco research startup, say they have used an AI model to predict which genetic mutations cause disease—and, crucially, to explain why—offering a ...

New technology enables the insertion of a large segment of DNA into a genome, potentially expanding gene therapy treatment ...

Some genetic disorders-such as cystic fibrosis, hemophilia and Tay Sachs disease-involve many mutations in a person's genome, often with enough variation that even two individuals who share the same ...

"It's a slow-moving train wreck," Mike Graglia says about his 12-year-old son Tony's rare genetic disease with no cure. Caused by a tiny fluke of nature—a mutation in a gene known as a SYNGAP1—the non ...
