Labcorp Genetics (formerly Invitae), Labcorp RCV000650279 SCV000772119 uncertain significance Hereditary spastic paraplegia 54 2017-09-21 criteria provided, single submitter clinical testing This sequence change replaces alanine with valine at codon 143 of the DDHD2 protein (p.Ala143Val). The alanine residue is highly conserved and there is a small physicochemical difference between alanine and valine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with DDHD2-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: "Possibly Damaging"; Align-GVGD: "Class C0"). 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.
