RCV002942260 | SCV003267153 | uncertain significance | Congenital amegakaryocytic thrombocytopenia; Essential thrombocythemia | 2022-08-12 | criteria provided, single submitter | clinical testing | This sequence change replaces lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 573 of the MPL protein (p.Lys573Glu). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with MPL-related conditions. 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 glutamic acid amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. |
