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 creates a premature translational stop signal (p.Trp409*) in the NEK1 gene. RNA analysis indicates that this premature translational stop signal induces altered splicing and likely results in a shortened protein product. This variant is present in population databases (no rsID available, gnomAD 0.004%). This premature translational stop signal has been observed in individual(s) with clinical features of a skeletal ciliopathy (PMID: 27530628, 29068549). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 446672). Studies have shown that this premature translational stop signal results in skipping of exon 15, but is expected to preserve the integrity of the reading-frame (PMID: 27530628). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -
