Labcorp Genetics (formerly Invitae), Labcorp RCV000802271 SCV000942095 uncertain significance Ehlers-Danlos syndrome, spondylocheirodysplastic type 2019-01-07 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 output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The valine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. 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 SLC39A13-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces isoleucine with valine at codon 324 of the SLC39A13 protein (p.Ile324Val). The isoleucine residue is highly conserved and there is a small physicochemical difference between isoleucine and valine.
