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

Classification was made for transcript

Our verdict: Pathogenic. The variant received 10 ACMG points.

PVS1

Start lost variant, next in-frame start position is after 20 pathogenic variants. Next in-frame start position is after 16 codons. Genomic position: 35119568. Lost 0.047 part of the original CDS.

PS1

Another start lost variant in NM_002878.4 (RAD51D) was described as [Likely_pathogenic] in ClinVar

PP5

Variant 17-35119613-T-C is Pathogenic according to our data. Variant chr17-35119613-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 127884.

BS2

High AC in GnomAdExome4 at 5 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
