Description

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

Description

Variant summary: RAD51D c.904-3C>T alters a non-conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. 4/4 computational tools predict no significant impact on normal splicing. Experimental evidence supports these predictions indicating the variant has no effect on splicing (Casadei_2019). The variant allele was found at a frequency of 0.00024 in 253596 control chromosomes, predominantly at a frequency of 0.00044 within the Non-Finnish European subpopulation in the gnomAD database. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 3.5-fold of the estimated maximal expected allele frequency for a pathogenic variant in RAD51D causing Hereditary Breast And Ovarian Cancer Syndrome phenotype (0.00013), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Non-Finnish European origin. The variant, c.904-3C>T, has been reported in the literature in individuals affected with Hereditary Breast and Ovarian Cancer, Lynch Syndrome and pancreatic ductal adenocarcinoma (Osher_2012, Tung_2015, Yurgelun_2015, Chaffee_2018), however it was also observed in controls (Loveday_2011). These reports do not provide unequivocal conclusions about association of the variant with Hereditary Breast And Ovarian Cancer Syndrome. Six ClinVar submitters (evaluation after 2014) cite the variant as benign/likely benign and five ClinVar submitters (evaluation after 2014) cite it as uncertain significance. Based on the evidence outlined above, the variant was classified as benign.
