The integrative recommendations for BRCA testing presented here aim to (1) identify indi- viduals who may benefit from genetic counselling and risk-reducing strategies; (2) update germline and tumour-testing indications for PARPi-approved therapies; (3) provide testing
This overview of clinical management guidelines is based on this patient’s positive test result for a BRCA2 gene mutation. Unless otherwise stated, medical management guidelines used here are limited to those issued by the National Comprehensive Cancer Network® (NCCN®)1 in the U.S.
4 Σεπ 1998 · BRCA1- and BRCA2- associated hereditary breast and ovarian cancer (HBOC) is characterized by an increased risk for female and male breast cancer, ovarian cancer (including fallopian tube and primary peritoneal cancers), and to a lesser extent other cancers such as prostate cancer, pancreatic cancer, and melanoma primarily in individuals with a ...
BRCA1 and BRCA2 are high-penetrance breast cancer predisposition genes identified by genome-wide linkage analysis and positional cloning. Mutations in BRCA1/2 explain ∼20% of the familial clustering of breast cancer.

Men who have a BRCA1 gene mutation have a 0.1-1% risk of breast cancer and a prostate cancer risk which is similar to (or may be slightly more than) the population risk. A man with a BRCA2 gene mutation may have a 5-10% lifetime breast cancer risk and 20-25% lifetime risk of prostate cancer.
rley et al 2019; Rahman et al 2019) The Cancer Genome Atlas (TCGA) identified somatic and germline BRCA pathogenic variants in ~22% of high-grade serous ovarian cancers (TCGA 2011). To manage this increased demand and ensure timely access to testing ear.
