Genes affected
RAD51D (HGNC:9823): (RAD51 paralog D) The protein encoded by this gene is a member of the RAD51 protein family. RAD51 family members are highly similar to bacterial RecA and Saccharomyces cerevisiae Rad51, which are known to be involved in the homologous recombination and repair of DNA. This protein forms a complex with several other members of the RAD51 family, including RAD51L1, RAD51L2, and XRCC2. The protein complex formed with this protein has been shown to catalyze homologous pairing between single- and double-stranded DNA, and is thought to play a role in the early stage of recombinational repair of DNA. Alternative splicing results in multiple transcript variants. Read-through transcription also exists between this gene and the downstream ring finger and FYVE-like domain containing 1 (RFFL) gene.

Benign, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpOct 15, 2020Variant summary: RAD51D c.196G>A (p.Val66Met) results in a conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00032 in 251384 control chromosomes, predominantly at a frequency of 0.0036 within the East Asian subpopulation in the gnomAD database. The observed variant frequency within East Asian control individuals in the gnomAD database is approximately 29 fold of the estimated maximal expected allele frequency for a pathogenic variant in RAD51D causing Hereditary Breast And Ovarian Cancer Syndrome phenotype (0.00013). In addition, allele frequency of this variant in 8380 Japanese controls is 0.0137 (jMorp database). These data strongly suggest that the variant is a benign polymorphism found primarily in populations of East Asian origin. c.196G>A has been reported in the literature in individuals affected with various types of cancer (Lu_2015, Yurgelun_2017, Hauke_2018, Wei_2019). These reports do not provide unequivocal conclusions about association of the variant with Hereditary Breast And Ovarian Cancer Syndrome. Co-occurrence with a pathogenic variant has been reported (BRCA2 c.571_572insAT, p.D191fs, Wei_2019), providing supporting evidence for a benign role. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Seven clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Multiple laboratories reported the variant with conflicting assessments (benign/likely benign n=4, VUS n=3). Based on the evidence outlined above, the variant was classified as benign. -
