RCV000228735 | SCV000288886 | uncertain significance | Congenital amegakaryocytic thrombocytopenia; Thrombocythemia 1 | 2016-01-30 | criteria provided, single submitter | clinical testing | This sequence change replaces leucine with proline at codon 31 of the MPL protein (p.Leu31Pro). The leucine residue is highly conserved and there is a moderate physicochemical difference between leucine and proline. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a MPL-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C65"). In summary, this is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. |
