Variant summary
Our verdict is Likely benign. Variant got -1 ACMG points: 0P and 1B. BP6
The NM_000179.3(MSH6):c.3071G>A(p.Arg1024Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000561 in 1,602,968 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1024W) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:2
Uncertain significance, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Aug 10, 2023 | This missense variant replaces arginine with glutamine at codon 1024 of the MSH6 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with MSH6-related disorders in the literature. This variant has been identified in 2/274522 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. - |
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Nov 01, 2022 | The p.R1024Q variant (also known as c.3071G>A), located in coding exon 4 of the MSH6 gene, results from a G to A substitution at nucleotide position 3071. The arginine at codon 1024 is replaced by glutamine, an amino acid with highly similar properties. In one study, this variant was detected in 0/165 colorectal cancer and/or polyposis patients and was identified in 1/2512 control individuals from a healthy population database (Rosenthal EA et al. Hum. Genet., 2018 Oct;137:795-806). This amino acid position is well conserved in mammals, but not in lower available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |

Likely benign, criteria provided, single submitter | clinical testing | Myriad Genetics, Inc. | Mar 29, 2023 | This variant is considered likely benign. This variant is strongly associated with less severe personal and family histories of cancer, typical for individuals without pathogenic variants in this gene [PMID: 25085752]. - |
