Variant summary
Our verdict is Benign. The variant received -10 ACMG points: 0P and 10B. BP4_ModerateBP6_Very_Strong
The NM_000059.4(BRCA2):c.3568C>T(p.Arg1190Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000589 in 1,613,918 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1190L) has been classified as Likely benign.

Variant summary: BRCA2 c.3568C>T (p.Arg1190Trp) results in a non-conservative amino acid change in the encoded protein sequence. Three of four in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00011 in 251026 control chromosomes. This frequency is not significantly higher than expected for a pathogenic variant in BRCA2 causing Hereditary Breast And Ovarian Cancer Syndrome (0.00011 vs 0.00075), allowing no conclusion about variant significance. c.3568C>T has been reported in the literature in individuals affected with Hereditary Breast And Ovarian Cancer Syndrome. These reports do not provide unequivocal conclusions about association of the variant with Hereditary Breast And Ovarian Cancer Syndrome. Eight clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation (benign/likely benign n=7, VUS n=1). In addition, one expert panel classified this variant as benign. Based on the evidence outlined above, the variant was classified as benign.
not provided Benign:3
This variant is associated with the following publications: (PMID: 17924331, 26243651, 21990134, 20127978, 24323938, 27124784, 24504028, 27495310, 28866612, 29349598, 25348012)
BRCA2: BP4
Hereditary cancer-predisposing syndrome Benign:3
This alteration is classified as 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.
Hereditary breast ovarian cancer syndrome Benign:2
Breast and/or ovarian cancer Benign:1
BRCA2-related cancer predisposition Benign:1
BRCA2-related disorder Benign:1
This variant is classified as benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications).
