Color Diagnostics, LLC DBA Color Health RCV001184569 SCV001350589 uncertain significance Hereditary cancer-predisposing syndrome 2023-12-04 criteria provided, single submitter clinical testing This missense variant replaces histidine with tyrosine at codon 536 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 1/251496 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.
Ambry Genetics RCV001184569 SCV002706435 uncertain significance Hereditary cancer-predisposing syndrome 2021-12-20 criteria provided, single submitter clinical testing The p.H536Y variant (also known as c.1606C>T), located in coding exon 16 of the MUTYH gene, results from a C to T substitution at nucleotide position 1606. The histidine at codon 536 is replaced by tyrosine, an amino acid with 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.
GeneDx RCV003313182 SCV004012700 uncertain significance not provided 2023-01-06 criteria provided, single submitter clinical testing Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
