Variant summary
Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP6
The NM_007294.4(BRCA1):c.2963C>T(p.Ser988Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000372 in 1,613,838 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. S988S) has been classified as Benign.

Submissions by phenotype
Hereditary cancer-predisposing syndrome    Benign:3 
- -
This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
Missense variant in a coldspot region where missense variants are very unlikely to be pathogenic (PMID:31911673). -

Not observed at a significant frequency in large population cohorts (Lek et al., 2016); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 25722345, 22476429, 27767231, 31131967, 32546644, 30212499) -
