Labcorp Genetics (formerly Invitae), Labcorp RCV001308907 SCV001498382 uncertain significance Cone-rod dystrophy 6; Leber congenital amaurosis 1 2020-03-19 criteria provided, single submitter clinical testing 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. 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. This variant has not been reported in the literature in individuals with GUCY2D-related conditions. This sequence change replaces threonine with serine at codon 203 of the GUCY2D protein (p.Thr203Ser). The threonine residue is moderately conserved and there is a small physicochemical difference between threonine and serine. This variant is not present in population databases (ExAC no frequency).
