Submissions by phenotype
Breast-ovarian cancer, familial, susceptibility to, 4 Benign:4
- -
- -
This variant is considered benign. This variant is intronic and is not expected to impact mRNA splicing. This variant is strongly associated with less severe personal and family histories of cancer, typical for individuals without pathogenic variants in this gene [PMID: 25085752]. -

Hereditary cancer-predisposing syndrome Benign:3

BP4, BP7 c.263+7G>A is an intronic variant not very close to a canonical splice site, where the SpliceAI algorithm predicts no significant impact on splicing (BP4 and BP7). This variant is found in 6/268236 alleles at a frequency of 0.0022% in the gnomAD v2.1.1 database, non-cancer dataset. To our knowledge, neither relevant clinical data nor functional studies have been reported for this variant. It has been identified in a patient affected with breast cancer (internal data). It has only been reported in ClinVar (8x as likely benign). Based on currently available information, the variant c.263+7G>A should be considered a likely benign variant. -

not specified Benign:2
Variant summary: RAD51D c.263+7G>A 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. Consensus agreement among computation tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 2.4e-05 in 1605330 control chromosomes, predominantly at a frequency of 0.0003 within the Latino subpopulation in the gnomAD database (v4.1 dataset). The observed variant frequency within Latino control individuals in the gnomAD database is approximately 2.4-fold of the estimated maximal expected allele frequency for a pathogenic variant in RAD51D causing Hereditary Breast And Ovarian Cancer Syndrome phenotype (0.00013). To our knowledge, no occurrence of c.263+7G>A in individuals affected with Hereditary Breast And Ovarian Cancer Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 384514). Based on the evidence outlined above, the variant was classified as benign. -
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. -
