Ambry Genetics	RCV000129189	SCV000183927	uncertain significance	Hereditary cancer-predisposing syndrome	2022-08-05	criteria provided, single submitter	clinical testing	The p.G56V variant (also known as c.167G>T), located in coding exon 3 of the MUTYH gene, results from a G to T substitution at nucleotide position 167. The glycine at codon 56 is replaced by valine, an amino acid with dissimilar properties. This amino acid position is not well 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.

Labcorp Genetics (formerly Invitae), Labcorp	RCV000409275	SCV000639300	uncertain significance	Familial adenomatous polyposis 2	2024-01-11	criteria provided, single submitter	clinical testing	This sequence change replaces glycine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 56 of the MUTYH protein (p.Gly56Val). This variant is present in population databases (rs587781374, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with MUTYH-related conditions. ClinVar contains an entry for this variant (Variation ID: 140924). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. 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.
Color Diagnostics, LLC DBA Color Health	RCV000129189	SCV000905866	uncertain significance	Hereditary cancer-predisposing syndrome	2023-07-26	criteria provided, single submitter	clinical testing	This missense variant replaces glycine with valine at codon 56 of the MUTYH 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 MUTYH-related disorders in the literature. This variant has been identified in 2/248342 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.
