Ambry Genetics | RCV000216683 | SCV000276710 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-02-28 | criteria provided, single submitter | clinical testing | The p.I906M variant (also known as c.2718A>G), located in coding exon 16 of the MSH2 gene, results from an A to G substitution at nucleotide position 2718. The isoleucine at codon 906 is replaced by methionine, an amino acid with highly similar properties. This amino acid position is poorly 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. |

RCV000216683 | SCV001345630 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-05-17 | criteria provided, single submitter | clinical testing | This missense variant replaces isoleucine with methionine at codon 906 of the MSH2 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with MSH2-related disorders in the literature. This variant has been identified in 1/31414 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. |

RCV003997983 | SCV004829909 | uncertain significance | Lynch syndrome | 2023-06-08 | criteria provided, single submitter | clinical testing | This missense variant replaces isoleucine with methionine at codon 906 of the MSH2 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 1/31414 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. |
