BRCA2

Aka: BRCA2
  1. Pathophysiology
    1. BRCA2, like BRCA1, normally functions as a DNA repair gene, and in effect, a tumor suppressor gene
    2. Chromosome 13q12-13
  2. Epidemiology
    1. Responsible for a third of hereditary Breast Cancer
    2. Affects Male as well as Female carriers of the genetic mutation
  3. Associated Conditions
    1. Ovarian Cancer risk: 11-20% (less than BRCA1)
      1. Typically high grade serous Phenotype
    2. Prostate Cancer: <40%
    3. Pancreatic Cancer: 2 to 7%
    4. Breast Cancer in Men: 5 to 10%
    5. Breast Cancer risk in women: 40 to 70% (up to 90% in some studies)
      1. Typically sporadic Phenotype (ER positive, HER2 negative)
      2. Second primary Breast Cancer 12% within 5 years (40 to 50% at 20 years)
      3. Age 20-29: Relative Risk Breast Cancer 46
      4. Age 30-39 Relative Risk Breast Cancer 38
      5. Age 40-49: Relative Risk Breast Cancer 13
      6. Age 50-59: Relative Risk Breast Cancer 9.8
      7. Age 60-69: Relative Risk Breast Cancer 2.1

BRCA2 Protein (C0294028)

Definition (NCI) Breast cancer type 2 susceptibility protein (3418 aa, ~384 kDa) is encoded by the human BRCA2 gene. This protein plays a role in both cell cycle regulation and DNA repair.
Definition (MSH) A large, nuclear protein, encoded by the BRCA2 gene (GENE, BRCA2). Mutations in this gene predispose humans to breast and ovarian cancer. The BRCA2 protein is an essential component of DNA repair pathways, suppressing the formation of gross chromosomal rearrangements. (from Genes Dev. 2000;14(11):1400-6)
