Variant summary

Our verdict is Pathogenic. The variant received 22 ACMG points: 22P and 0B. PVS1 PS3 PM2 PP5_Very_Strong

The NM_002878.4(RAD51D):​c.772_778delGGGAGGC​(p.Gly258SerfsTer50) variant causes a frameshift change. The variant allele was found at a frequency of 0.00000137 in 1,461,830 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Likely pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV000570461: Published functional studies demonstrate a damaging effect: sensitivity to platinum-based chemotherapy and PARP inhibitors (Kondrashova 2017)". Synonymous variant affecting the same amino acid position (i.e. G258G) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

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.

ACMG classification

Our verdict: Pathogenic. The variant received 22 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PS3: PS3 evidence extracted from ClinVar submissions: SCV000570461: Published functional studies demonstrate a damaging effect: sensitivity to platinum-based chemotherapy and PARP inhibitors (Kondrashova 2017)
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 17-35101325-AGCCTCCC-A is Pathogenic according to our data. Variant chr17-35101325-AGCCTCCC-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 421303.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
