Labcorp Genetics (formerly Invitae), Labcorp RCV001305700 SCV001495046 uncertain significance Hereditary spastic paraplegia 43 2020-03-09 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but 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 C19orf12-related conditions. This variant is present in population databases (rs752858139, ExAC 0.02%). This sequence change replaces alanine with valine at codon 120 of the C19orf12 protein (p.Ala120Val). The alanine residue is weakly conserved and there is a small physicochemical difference between alanine and valine.
