Labcorp Genetics (formerly Invitae), Labcorp RCV001237170 SCV001409921 uncertain significance Nephronophthisis 2022-06-03 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 1285 of the NPHP4 protein (p.Gly1285Ala). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with NPHP4-related conditions. ClinVar contains an entry for this variant (Variation ID: 963174). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The alanine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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.
