Notes

rs80359507, also known as 5578delAA, c.5350_5351delAA and p.Asn1784Hisfs, is a variant in the BRCA2 gene considered pathogenic for breast cancer in ClinVar. Note the many different mutations all now lumped by dbSNP under a single rsID; at a minimum, these include delAAA, delAA, delA, dupA and dupAA. Of these 5, all are considered pathogenic except for the first, delAAA, which is of uncertain significance. 23andMe name for c.5351delA: i5009103
