Hereditary cancer-predisposing syndrome Uncertain:2
This missense variant replaces valine with methionine at codon 151 of the RAD51C protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). Splice site prediction tools suggest that this variant may not impact RNA splicing. To our knowledge, functional studies have not been performed for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has been identified in 5/251484 chromosomes 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. -
The c.451G>A (p.V151M) alteration is located in exon 3 (coding exon 3) of the RAD51C gene. This alteration results from a G to A substitution at nucleotide position 451, causing the valine (V) at amino acid position 151 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Breast-ovarian cancer, familial, susceptibility to, 3 Uncertain:2
The missense c.451G>A (p.Val151Met) variant in RAD51C gene has been submitted to ClinVar as a Variant of Uncertain Significance, but no details are available for independent assessment. It has not been reported in affected individuals. The p.Val151Met variant is observed in 0.001% alleles in gnomAD Exomes and is novel (not in any individuals) in 1000 Genomes. The amino acid Val at position 151 is changed to a Met changing protein sequence and it might alter its composition and physico-chemical properties. For these reasons, this variant has been classified as Uncertain significance. -

not provided Uncertain:1
Not observed at a significant frequency in large population cohorts (Lek et al., 2016); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Fanconi anemia complementation group O Uncertain:1
This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 151 of the RAD51C protein (p.Val151Met). This variant is present in population databases (rs753912045, gnomAD 0.02%). 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: 234035). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt RAD51C protein function with a negative predictive value of 80%. 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. -
