ENIGMA BRCA1 and BRCA2 VCEP
The c.3082C>T variant in BRCA1 is a missense variant predicted to cause substitution of Arginine by Cysteine at amino acid 1028 (p.Arg1028Cys). This variant is present in gnomAD v2.1 (exomes only, non-cancer subset) or gnomAD v3.1 (non-cancer subset) but is below the ENIGMA BRCA1/2 VCEP threshold >0.00002 for BS1_Supporting (PM2_Supporting, BS1, and BA1 are not met). This missense variant is located outside of a key functional domain and was not predicted to alter mRNA splicing using the SpliceAI predictor (score 0.01, score threshold < 0.1) (BP1_Strong met). Reported by one calibrated study to exhibit protein function similar to benign control variants (PMID: 32546644) (BS3 met). This variant has been observed in one individual with features considered inconsistent with an FA-associated phenotype, variant is homozygous (total score 1 point) (BS2_Supporting met; PMID: 29435075). Multifactorial likelihood ratio analysis using clinically calibrated data produced a combined LR for this variant of 0.0009 (based on Cosegregation LR=0.131; Pathology LR=0.056; Co-occurrence LR= 1.527; Family History LR= 0.081), below the thresholds for very strong benign evidence (LR <0.00285) (BP5_Very strong met; PMID: 31131967). 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 (BP1_Strong, BS3, BS2_Supporting, BP5_Very strong).
