Notes
rs80359306, also known as c.1813dupA, 2034insA, c.1806_1807insA and p.Gly602_Lys603?fs, is a variant in the BRCA2 gene considered pathogenic for breast cancer in ClinVar. dbSNP has merged rs80359307 into this SNP, rs80359306, so it may now also represent c.1813delA, which is also pathogenic in ClinVar for breast cancer.
-;A
See text and links via main rs-page. Note: if the raw data is "DI" for this SNP, due to ambiguity it could either represent c.1813dupA or c.1813delA.
