Description

This sequence change replaces serine with tyrosine at codon 1722 of the BRCA1 protein (p.Ser1722Tyr). The serine residue is highly conserved and there is a large physicochemical difference between serine and tyrosine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with BRCA1-related conditions. ClinVar contains an entry for this variant (Variation ID: 491098). This variant has been reported to have conflicting or insufficient data to determine the effect on BRCA1 protein function (PMID: 30209399). This variant disrupts the p.Ser1722 amino acid residue in BRCA1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 20516115, 12496477, 25085752). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
