(A;T) 6 BRCA2 variant considered pathogenic for breast cancer; however, 23andMe data appears to be prone to false positives for this SNP

See details via ClinVar link on main SNP/rs# page; note, though, that Promethease user data (including subsequent clinical/confirmatory testing) is implying that at least for 23andMe customers, there may be a significant number of false positives for this genotype.

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.
