Labcorp Genetics (formerly Invitae), Labcorp RCV002628131 SCV003509660 uncertain significance Nephronophthisis 2021-12-14 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). 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 asparagine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with NPHP4-related conditions. This sequence change replaces lysine, which is basic and polar, with asparagine, which is neutral and polar, at codon 83 of the NPHP4 protein (p.Lys83Asn).
