Mutations are changes in DNA that range from harmless to life-altering. Learn what they are, how they happen, and what they mean for your health.
Four classes of mutations are (1) spontaneous mutations (molecular decay), (2) mutations due to error-prone replication bypass of naturally occurring DNA damage (also called error-prone translesion synthesis), (3) errors introduced during DNA repair, and (4) induced mutations caused by mutagens.
KIT-exon-11 mutations in GISTs correlate with higher partial response rates and improved surgical outcomes with neoadjuvant Gleevec. Non-KIT exon 11 mutations and wild-type KIT/PDGFRA GISTs show less ...

An individual offspring inherits mutations only when mutations are present in parental egg or sperm cells (germinal mutations). All of the offspring’s cells will carry the mutated DNA, which often confers some serious malfunction, as in the case of a human genetic disease such as cystic fibrosis.
While some genetic mutations can lead to genetic conditions, most mutations don’t cause symptoms in humans. It’s difficult to prevent mutations from happening, especially as genetic mutations can occur randomly — some without being present in your family history.
A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses.
Mutations are changes in the information contained in genetic material. For most of life, this means a change in the sequence of DNA, the hereditary material of life.
