Labcorp Genetics (formerly Invitae), Labcorp RCV002933087 SCV003262958 uncertain significance Nephronophthisis 14 2023-12-06 criteria provided, single submitter clinical testing This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 983 of the ZNF423 protein (p.Lys983Arg). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ZNF423-related conditions. ClinVar contains an entry for this variant (Variation ID: 2054953). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt ZNF423 protein function with a negative predictive value of 80%. 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.
