In simple terms: a mutation is a stable change in genetic sequence that can be copied when cells or viruses replicate. Most mutations have no detectable effect, some contribute to disease, and a small ...

About 25% of lung adenocarcinomas have mutations of the gene KRAS, which drives uncontrolled cell growth. In recent years, ...

A new study of 450 colorectal cancer patients has delivered some of the clearest evidence yet that mutations in two DNA proofreading genes, POLE and POLD1, can identify which patients are most likely ...

KRAS is the most frequently mutated oncogene across all human cancers. Although different KRAS mutations have long been thought to exert the same cancer-driving effects, a new study led by UT ...

A study led by the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC), working in collaboration with an international research team, has identified a new molecular mechanism ...

KRAS mutations lead to excessive cell growth due to alterations in the KRAS gene. They are present in a significant percentage of non-small cell lung cancers (NSCLC). Diagnosis involves testing ...

The inherited mutation substantially increases the chance of developing lung cancer, including in people who don't smoke.

Researchers at the Institute for Bioengineering of Catalonia (IBEC) have produced a mutational map showing how mutations in amylin—a hormone that plays a key role in glucose regulation—affect its ...

Mutations are changes in the molecular "letters" that make up DNA, the genetic blueprint for cells. Mutations build up with age in every cell when DNA is damaged or when cells make mistakes in fixing ...
