Not observed at a significant frequency in large population cohorts (Lek 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; Published functional studies demonstrate a damaging effect: severely affected glycosylation and suppression of oxidative mutagenesis (Goto 2010, Shinmura 2012, Komine 2015); Observed in the compound heterozygous state with known pathogenic variants in multiple individuals with a phenotype consistent with MUTYH-associated polyposis (MAP) (Isidro 2004, Aretz 2006, Di Gregorio 2006, Nielsen 2009, Morak 2010); This variant is associated with the following publications: (PMID: 20848659, 25820570, 16207212, 17273161, 19032956, 23507534, 30604180, 23322991, 15366000, 14961129, 16890597, 16557584, 19394335, 20618354, 23605219, 21901162, 26681312, 28452373, 27783336, 29478780, 30291343, 32283892, 31589614)

The best available variant frequency is uninformative because it is below the disease allele frequency. Found in at least one patient with expected phenotype for this gene. Other pathogenic or likely pathogenic variants affect the same amino acid . In multiple individuals, this variant has been seen with a single recessive pathogenic variant in the same gene, suggesting this variant may also be pathogenic. Assessment of experimental evidence suggests this variant results in abnormal protein function.
