Notes

rs80359479 represents at least four different variants in the BRCA2 gene; three are considered pathogenic for breast cancer in ClinVar and one is of uncertain significance. The three pathogenic mutations are: c.5073del, c.5070_5073delAAAA and c.5073dupA. The variant of uncertain significance (at the time of this edit) is c.5068_5073dupAAAAAA.
