RCV001931941 | SCV002122847 | uncertain significance | Nephronophthisis 14 | 2022-10-03 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 380 of the ZNF423 protein (p.Arg380Cys). This variant is present in population databases (no rsID available, gnomAD 0.003%). 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: 1361750). 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. 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. |

| Ambry Genetics | RCV004039779 | SCV003614161 | uncertain significance | not specified | 2022-04-07 | criteria provided, single submitter | clinical testing | The c.1138C>T (p.R380C) alteration is located in exon 5 (coding exon 4) of the ZNF423 gene. This alteration results from a C to T substitution at nucleotide position 1138, causing the arginine (R) at amino acid position 380 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
