The available evidence is currently insufficient to determine its role in disease. 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but 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 a POLD1-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces histidine with proline at codon 48 of the POLD1 protein (p.His48Pro). The histidine residue is weakly conserved and there is a moderate physicochemical difference between histidine and proline. |
