Notes

rs80359671, also known as 995del5, c.767_771delCAAAT and p.Thr256_Asn257?fs, represents a 5bp deletion in the BRCA2 gene considered pathogenic for breast cancer in ClinVar. An alternative rs# for this same deletion is rs80359675. The BRCA2 999del5 deletion has been associated with significantly increased risk for breast cancer as well as some other cancers, at least in certain populations; this mutation is also considered a founder mutation among people from Iceland. For more information, see OMIM 600185.0010.
