Labcorp Genetics (formerly Invitae), Labcorp RCV001061640 SCV001226389 uncertain significance Developmental and epileptic encephalopathy, 12 2020-01-02 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 PLCB1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces leucine with valine at codon 944 of the PLCB1 protein (p.Leu944Val). The leucine residue is moderately conserved and there is a small physicochemical difference between leucine and valine.
