Ambry Genetics | RCV000568650 | SCV000666467 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-11-22 | criteria provided, single submitter | clinical testing | The p.V76L variant (also known as c.226G>T), located in coding exon 3 of the MUTYH gene, results from a G to T substitution at nucleotide position 226. The valine at codon 76 is replaced by leucine, an amino acid with highly similar 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. |

RCV000811833 | SCV000952120 | uncertain significance | Familial adenomatous polyposis 2 | 2024-08-04 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 76 of the MUTYH protein (p.Val76Leu). This variant is not present in population databases (gnomAD no frequency). 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: 481796). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The leucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. |
