Genes affected

NEK1 (HGNC:7744): (NIMA related kinase 1) The protein encoded by this gene is a serine/threonine kinase involved in cell cycle regulation. The encoded protein is found in a centrosomal complex with FEZ1, a neuronal protein that plays a role in axonal development. Defects in this gene are a cause of polycystic kidney disease (PKD). Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2010]

This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 1019 of the NEK1 protein (p.Ser1019Leu). This variant is present in population databases (rs377607698, gnomAD 0.008%). This missense change has been observed in individual(s) with NEK1-related conditions (PMID: 28089114). This variant is also known as c.C3140T; p.S1047L. ClinVar contains an entry for this variant (Variation ID: 266054). 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 expected to disrupt NEK1 protein function with a positive 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. -
