You appear to be a carrier for the rs796856605 SNP, which is (far) more commonly known as the 185delAG BRCA1 mutation. Your lifetime risk of breast cancer for women is increased from ~13% to ~81% and risk of ovarian cancer is increased from less than ~2% to over 50%. This SNP may significantly increase the risk of prostate cancer in men. There is also a somewhat increased risk for breast cancer in men from this genotype. See additional discussion at rs796856605.
This is a genotype with recommended actions if clinically confirmed. In brief:
- More frequent and more intensive screening for breast and ovarian cancer is recommended starting at perhaps age 25; however, screening has not been shown to reduce breast cancer incidence.
- Prophylactic surgery (e.g. bilateral mastectomy or salpingo-oophorectomy) has been shown to substantially reduce the risk for, as well as mortality from, breast or ovarian cancer in both high-risk women and those who are BRCA mutation carriers.
- Genetic counseling and/or testing is recommended for first-degree relatives as well as the same surveillance as carriers.

Genetic counseling may be available to you through your health-care network. In the US, genetic counselors may be found via this webpage of the National Society of Genetic Counselors.
