The p.Q463R variant (also known as c.1388A>G), located in coding exon 14 of the MUTYH gene, results from an A to G substitution at nucleotide position 1388. The glutamine at codon 463 is replaced by arginine, an amino acid with highly similar properties. Of note, this alteration is also designated as c.1346A>G (p.Q449R) in published literature. 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.

HelpRecord last updated May 01, 2024
This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
