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]

Short-rib thoracic dysplasia 6 with or without polydactyly Uncertain:1
Nov 30, 2021
Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This missense change has been observed in individual(s) with NEK1-related conditions (PMID: 28089114). This variant is present in population databases (no rsID available, gnomAD 0.002%). This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 770 of the NEK1 protein (p.Leu770Val). This variant is also known as c.2392C>G. 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. 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 not expected to disrupt NEK1 protein function. ClinVar contains an entry for this variant (Variation ID: 266053). -
