BRCA mutation
BRCA Mutation
BRCA mutation (pronounced: /ˈbɹækə mjuːˈteɪʃən/) refers to a change or alteration in the BRCA1 or BRCA2 genes. These genes are responsible for producing tumor suppressor proteins that help repair damaged DNA. Mutations in these genes can lead to an increased risk of certain types of cancer, most notably breast and ovarian cancer.
Etymology
The term "BRCA" is an abbreviation of BReast CAncer. The term "mutation" comes from the Latin "mutatio", meaning "a changing".
