Notes
rs80359284, also known as 1636insG, c.1408_1409insG and p.Glu470?fs, is a variant in the BRCA2 gene considered pathogenic for breast cancer in ClinVar. Note: we have received information from a Promethease user that indicates 23andMe and possibly other "DNA-chip based" companies are prone to making an error for this mutation; the raw data from such companies will say the rs80359284 mutation is present, but when clinically tested, it turns out that a (benign, harmless) variant known as rs750341436 is present at this same position in the genome instead. We do not know how often this mistake occurs and at this time we have only a single report of this happening.
