RCV000773765 | SCV000907465 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-09-19 | criteria provided, single submitter | clinical testing | This missense variant replaces valine with leucine at codon 474 of the MSH6 protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual affected with prostate cancer (doi: 10.1101/2021.04.15.21255554). 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. |

RCV001373902 | SCV001570641 | uncertain significance | Hereditary nonpolyposis colorectal neoplasms | 2023-12-15 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 474 of the MSH6 protein (p.Val474Leu). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with MSH6-related conditions. ClinVar contains an entry for this variant (Variation ID: 629077). 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 not expected to disrupt MSH6 protein function with a negative predictive value of 95%. 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. |
