Labcorp Genetics (formerly Invitae), Labcorp RCV001244539 SCV001417766 uncertain significance Nephronophthisis 14 2024-01-15 criteria provided, single submitter clinical testing This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 134 of the ZNF423 protein (p.Thr134Met). This variant is present in population databases (rs777988344, gnomAD 0.07%). 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: 969240). 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.
Ambry Genetics RCV004034791 SCV004984228 uncertain significance not specified 2022-04-08 criteria provided, single submitter clinical testing The c.401C>T (p.T134M) 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 401, causing the threonine (T) at amino acid position 134 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
