Variant summary: MSH6 c.1729C>T (p.Arg577Cys) results in a non-conservative amino acid change located in the DNA mismatch repair protein MutS, connector domain (IPR007860) of the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 2.8e-05 in 250210 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.1729C>T has been reported in the literature in an individual affected with MSI stable colorectal cancer and in an individual with colorectal cancer who met at least one of the revised Bethesda guidelines, as well as in individuals affected with other cancers within the Lynch Syndrome tumor spectrum, without strong evidence for causality (e.g.Hampel_2008, Loizidou_2014, Paulo_2018, Barbosa_2020). In a large study evaluating breast cancer cases and controls in the Breast Cancer Association Consortium (BCAC), the variant was reported in 9/60466 cases, and in 4/53461 controls (Dorling_2021 through LOVD). These report(s) do not provide unequivocal conclusions about association of the variant with Hereditary Nonpolyposis Colorectal Cancer. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 32658311, 33008098, 18809606, 25133505, 29659569, 33471991). ClinVar contains an entry for this variant (Variation ID: 89218). Based on the evidence outlined above, the variant was classified as uncertain significance. (less)

This missense variant replaces arginine with cysteine at codon 577 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 individuals affected with prostate (PMID: 29659569), ovarian (PMID: 33008098), breast (PMID: 33471991) and colorectal cancer (PMID: 18809606, 25133505). This variant has also been observed in healthy individuals in breast and pancreatic cancer case-control studies (PMID: 32980694, 33471991). This variant has been identified in 10/281608 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. (less)

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.

The MSH6 c.1729C>T (p.R577C) has been reported in heterozygosity in at least two individuals with colorectal cancer (PMID: 25133505,18809606). It was also identified in at least one individual with prostate cancer (PMID: 29659569), and in at least one individual with ovarian cancer (PMID: 33008098). It has been reported in a large case-control study of breast cancer in 9/60466 cases and 4/53461 controls (PMID: 33471991). This variant was observed in 10/281608 chromosomes in the Genome Aggregation Database (http://gnomad.broadinstitute.org, PMID: 32461654). The variant has been reported in ClinVar (Variation ID: 89218). In silico tools suggest the impact of the variant on protein function is deleterious, though no microsatellite instability or MSH6 protein deficiency were seen in patients carrying this variant (PMID: 29659569, 33008098). The evidence is insufficient to meet ACMG/AMP criteria for classifying the variant as benign or pathogenic. Thus, the clinical significance of this variant is currently uncertain. (less)
