Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The asparagine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with DNMT1-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces histidine with asparagine at codon 1443 of the DNMT1 protein (p.His1443Asn). The histidine residue is moderately conserved and there is a small physicochemical difference between histidine and asparagine. |
