Determination of the presence or absence of known harmful mutation(s) in the BRAC2 gene. BRCA1/BRCA2 genes play a central role in DNA repair and their mutations increase sensitivity to DNA-damaging agents. BRCA1/BRCA2 germline mutations significantly increase the risk of breast and ovarian cancer. The trait is Experimental Factor Ontology identifier EFO_0011022 (BRCA2 mutation carier statu). Also known as: BRCA2 carrier status, BRCA2 mutation status.
