ENIGMA BRCA1 and BRCA2 VCEP
The c.154C>T variant in BRCA1 is a missense variant predicted to cause substitution of Leucine by Phenylalanine at amino acid 52 (p.(Leu52Phe)). The Total GrpMax filtering allele frequency (the lower threshold of the 95% CI) in gnomAD v4.1 is 0.001942 in the East Asian genetic ancestry group (based on 103/44742 alleles) which is above the ENIGMA BRCA1/2 VCEP threshold (>0.001) for BA1 (BA1 met). In summary, this variant meets the criteria to be classified as a Benign variant for BRCA1-related cancer predisposition based on the ACMG/AMP criteria applied as specified by the ENIGMA BRCA1/2 VCEP (v1.2) (BA1).
