Therefore, it has been classified as a Variant of Uncertain Significance. This variant has not been reported in the literature in individuals affected with DNMT1-related conditions. This variant is present in population databases (rs766504703, gnomAD 0.004%). This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 286 of the DNMT1 protein (p.Val286Ala). ClinVar contains an entry for this variant (Variation ID: 573027). 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 alanine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. |

The valine at codon 270 is replaced by alanine, an amino acid with similar properties. This amino acid position is poorly 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. |
