Labcorp Genetics (formerly Invitae), Labcorp RCV001228193 SCV001400579 uncertain significance Nephronophthisis 2022-07-27 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 409 of the NPHP1 protein (p.Arg409His). This variant is present in population databases (rs766289967, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with NPHP1-related conditions. ClinVar contains an entry for this variant (Variation ID: 593284). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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.

PreventionGenetics, part of Exact Sciences RCV004735773 SCV005360188 uncertain significance NPHP1-related disorder 2024-09-10 no assertion criteria provided clinical testing The NPHP1 c.1226G>A variant is predicted to result in the amino acid substitution p.Arg409His. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.010% of alleles in individuals of East Asian descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
