Women who have a BRCA2 gene mutation have a higher risk of developing breast, ovarian and pancreatic cancer during their lifetime. This page explains more about these risks. It should be read with our general information about BRCA. If you have a BRCA2 mutation, it is important to talk to your genetics specialist about your cancer risk.

Brca2 gene mutation

A mutation that is typically a heritable, permanent change in the nucleotide sequence of the BRCA2 gene. Single nucleotide substitutions and small deletions or insertions (1-20 bases) account for the majority of mutations in the BRCA2 gene. A BRCA mutation is a mutation in either of the BRCA1 and BRCA2 genes, which are tumour suppressor genes. Hundreds of different types of mutations in these genes have been identified, some of which have been determined to be harmful, while others have no proven impact. BRCA2 mutations are usually insertions or deletions of a small number of DNA base pairs in the gene.
