The cysteine residue is highly conserved and there is a large physicochemical difference between cysteine and tryptophan. This variant is not present in population databases (ExAC no frequency). This variant has been observed in an individual affected with breast cancer (PMID: 27257965), and in a family with breast cancer (PMID: 29446198). ClinVar contains an entry for this variant (Variation ID: 224427). This variant affects the highly conserved Cys64 residue within the N-terminal RING domain of the BRCA1 protein (PMID: 22843421). This variant has been reported to affect BRCA1 protein function (PMID: 30209399). This variant disrupts the p.Cys64 amino acid residue in BRCA1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 15131401, 22034289, 23397983, 18489799, 19949876, 25085752, 19287957, 24516540, 23867111, 23161852, 12915465, 23161852, 23867111, 7894491, 21042765). This suggests that this residue is clinically-significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
