Labcorp Genetics (formerly Invitae), Labcorp RCV000527943 SCV000660412 uncertain significance Fanconi anemia complementation group O 2023-09-26 criteria provided, single submitter clinical testing This sequence change falls in intron 1 of the RAD51C gene. It does not directly change the encoded amino acid sequence of the RAD51C protein. It affects a nucleotide within the consensus splice site. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with RAD51C-related conditions. ClinVar contains an entry for this variant (Variation ID: 478777). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
Ambry Genetics RCV000576032 SCV000667118 uncertain significance Hereditary cancer-predisposing syndrome 2023-04-20 criteria provided, single submitter clinical testing The c.145+5C>A intronic variant results from a C to A substitution 5 nucleotides after coding exon 1 in the RAD51C gene. This nucleotide position is not well conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will not have any significant effect on splicing; however, direct evidence is insufficient at this time (Ambry internal data). Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
Color Diagnostics, LLC DBA Color Health RCV000576032 SCV000912024 uncertain significance Hereditary cancer-predisposing syndrome 2020-09-29 criteria provided, single submitter clinical testing This variant causes a C to A nucleotide substitution at the +5 position of intron 1 of the RAD51C gene. To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.
