RCV002544932 | SCV000819888 | uncertain significance | Pontocerebellar hypoplasia type 1A | 2018-04-03 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine with alanine at codon 369 of the VRK1 protein (p.Gly369Ala). The glycine residue is weakly conserved and there is a small physicochemical difference between glycine and alanine. This variant is not present in population databases (ExAC no frequency). In summary, the available evidence is currently insufficient to determine the role of this variant 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 output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The alanine 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 VRK1-related disease. |
