BRCA Mutation Status Sample Clauses

BRCA Mutation Status. The BRCA mutation status from prior testing (information in the source record) will be recorded (Table 2). Patients with a BRCA mutation (germline mutation or somatic mutation in tumor tissue) are classified as positive and patients who were tested and shown to not have a BRCA mutation will be classified as negative. Patients without known BRCA mutation status in the source record are classified as unknown. If a patient with unknown status is tested and is found to have a BRCA mutation, this patient is considered BRCA mutation positive in analyses.
