Variant summary: The BRCA1 c.2481A>C (p.Glu827Asp) variant involves the alteration of a non-conserved nucleotide. 3/4 in silico tools predict a benign outcome (SNPs&GO not captured due to low reliability index). This variant was found in 4/121702 control chromosomes at a frequency of 0.0000329, which does not exceed the estimated maximal expected allele frequency of a pathogenic BRCA1 variant (0.0010005). This variant has been reported in BrC pts as well as in normal controls in literatures. In addition, one clinical diagnostic laboratory via ClinVar classified this variant as likely benign and another lab via ClinVar classified this variant as VUS, without evidence to independently evaluate. Because of the absence of clinical information and the lack of functional studies, the variant was classified as a variant of uncertain significance (VUS) until additional information becomes available.
