Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4_Strong BP6 BS1 BS2

The NM_058216.3(RAD51C):​c.790G>A​(p.Gly264Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00314 in 1,613,062 control chromosomes in the GnomAD database, including 17 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G264V) has been classified as Uncertain significance.

Genes affected

RAD51C (HGNC:9820): (RAD51 paralog C) This gene is a member of the RAD51 family. RAD51 family members are highly similar to bacterial RecA and Saccharomyces cerevisiae Rad51 and are known to be involved in the homologous recombination and repair of DNA. This protein can interact with other RAD51 paralogs and is reported to be important for Holliday junction resolution. Mutations in this gene are associated with Fanconi anemia-like syndrome. This gene is one of four localized to a region of chromosome 17q23 where amplification occurs frequently in breast tumors. Overexpression of the four genes during amplification has been observed and suggests a possible role in tumor progression. Alternative splicing results in multiple transcript variants.

ACMG classification

Our verdict: Benign. The variant received -13 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.010389477).
• BP6: Variant 17-58709943-G-A is Benign according to our data. Variant chr17-58709943-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 128211.
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.002 (305/152166) while in subpopulation NFE AF = 0.00335 (228/68008). AF 95% confidence interval is 0.003. There are 1 homozygotes in GnomAd4. There are 133 alleles in the male GnomAd4 subpopulation. Median coverage is 30. This position passed quality control check.
• BS2: High Homozygotes in GnomAdExome4 at 16 AR,AD gene
