Genes affected

MUTYH (HGNC:7527): (mutY DNA glycosylase) This gene encodes a DNA glycosylase involved in oxidative DNA damage repair. The enzyme excises adenine bases from the DNA backbone at sites where adenine is inappropriately paired with guanine, cytosine, or 8-oxo-7,8-dihydroguanine, a major oxidatively damaged DNA lesion. The protein is localized to the nucleus and mitochondria. This gene product is thought to play a role in signaling apoptosis by the introduction of single-strand breaks following oxidative damage. Mutations in this gene result in heritable predisposition to colorectal cancer, termed MUTYH-associated polyposis (MAP). Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2017]

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Dec 24, 2023	This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 430 of the MUTYH protein (p.Pro430Leu). This variant is present in population databases (rs587780079, gnomAD 0.02%). This missense change has been observed in individual(s) with breast cancer (PMID: 35264596). ClinVar contains an entry for this variant (Variation ID: 127832). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". 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. -
Uncertain significance, criteria provided, single submitter	clinical testing	All of Us Research Program, National Institutes of Health	Apr 27, 2023	This missense variant replaces proline with leucine at codon 430 of the MUTYH protein. This variant is also known as c.1247C>T (p.Pro416Val) based on an alternative transcript (NM_001048171). Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been performed for this variant. In a large international case-control study, this variant was reported in 2/60466 breast cancer cases and 4/53461 controls (OR=0.442, 95%CI 0.081 to 2.414, p-value=0.429; PMID: 33471991). This variant has been identified in 7/282722 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. -

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Sep 27, 2022	The p.P430L variant (also known as c.1289C>T), located in coding exon 13 of the MUTYH gene, results from a C to T substitution at nucleotide position 1289. The proline at codon 430 is replaced by leucine, an amino acid with similar properties. This amino acid position is well conserved in available higher vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
