RCV001979282 | SCV002251480 | uncertain significance | Nephronophthisis | 2022-04-07 | 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 736 of the NPHP4 protein (p.Arg736Cys). This variant is present in population databases (rs372959036, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with NPHP4-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). 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 | RCV002564449 | SCV003536679 | uncertain significance | Inborn genetic diseases | 2022-02-10 | criteria provided, single submitter | clinical testing | The c.2206C>T (p.R736C) alteration is located in exon 17 (coding exon 16) of the NPHP4 gene. This alteration results from a C to T substitution at nucleotide position 2206, causing the arginine (R) at amino acid position 736 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
