Notes
rs397507736, also known as c.466_467insT and p.Asp156Valfs, is a rare variant in the BRCA2 gene. In some publications the minor allele is considered a founder mutation (for example, in Russia) pathogenic for breast cancer. However, in ClinVar this variant is currently tagged as of unknown significance.
