Labcorp Genetics (formerly Invitae), Labcorp RCV000820676 SCV000961398 uncertain significance Nephronophthisis 2022-08-16 criteria provided, single submitter clinical testing This sequence change replaces threonine, which is neutral and polar, with serine, which is neutral and polar, at codon 517 of the NPHP1 protein (p.Thr517Ser). This variant is present in population databases (rs189982575, gnomAD 0.009%). 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: 662925). 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: "Probably Damaging"; Align-GVGD: "Class C0"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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 RCV004735821 SCV005344871 uncertain significance NPHP1-related disorder 2024-03-20 no assertion criteria provided clinical testing The NPHP1 c.1550C>G variant is predicted to result in the amino acid substitution p.Thr517Ser. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0085% of alleles in individuals of Latino descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
