Ambry Genetics	RCV000572853	SCV000662447	uncertain significance	Hereditary cancer-predisposing syndrome	2022-10-21	criteria provided, single submitter	clinical testing	The p.P1169A variant (also known as c.3505C>G), located in coding exon 6 of the MSH6 gene, results from a C to G substitution at nucleotide position 3505. The proline at codon 1169 is replaced by alanine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.

Color Diagnostics, LLC DBA Color Health	RCV000572853	SCV001346697	uncertain significance	Hereditary cancer-predisposing syndrome	2023-06-28	criteria provided, single submitter	clinical testing	This missense variant replaces proline with alanine at codon 1169 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 not been reported in individuals affected with MSH6-related disorders in the literature. This variant has been identified in 2/251340 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.
