RCV001036887 | SCV001200274 | uncertain significance | Hepatic veno-occlusive disease-immunodeficiency syndrome | 2019-12-16 | criteria provided, single submitter | clinical testing | 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: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0". The leucine 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 SP110-related conditions. This variant is present in population databases (rs765229595, ExAC 0.01%). This sequence change replaces proline with leucine at codon 242 of the SP110 protein (p.Pro242Leu). The proline residue is moderately conserved and there is a moderate physicochemical difference between proline and leucine. |
