Notes
The reference allele for rs80359198 is (C), and all three substitution variants have been observed, albeit with quite different clinical implications: * c.9285C>G (p.Asp3095Glu) * c.9285C>A (p.Asp3095Glu); rarely observed * c.9285C>T (p.Asp3095=) The first two are classified as BRCA2 gene pathogenic mutations for breast cancer based on likelihood cited in ClinVar and in ; the third is considered benign by most ClinVar annotators.
