Labcorp Genetics (formerly Invitae), Labcorp RCV000473770 SCV000550228 uncertain significance Fanconi anemia complementation group O 2022-03-29 criteria provided, single submitter clinical testing This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 184 of the RAD51C protein (p.Ala184Thr). This variant is present in population databases (no rsID available, gnomAD 0.002%). 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: 409864). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt RAD51C protein function. 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 RCV000579716 SCV001186179 uncertain significance Hereditary cancer-predisposing syndrome 2023-04-04 criteria provided, single submitter clinical testing The p.A184T variant (also known as c.550G>A), located in coding exon 3 of the RAD51C gene, results from a G to A substitution at nucleotide position 550. The alanine at codon 184 is replaced by threonine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
