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]

The NEK1 c.1618C>T variant is predicted to result in premature protein termination (p.Arg540*). This variant was reported along with a second premature termination variant in a patient with short-rib thoracic dysplasia type II (Table S2, Zhang et al. 2017. PubMed ID: 29068549). This variant is reported in 0.0065% of alleles in individuals of African descent in gnomAD, including 11 heterozygous individuals in the gnomAD v4.1.0 dataset (https://gnomad.broadinstitute.org/variant/4-169537856-G-A?dataset=gnomad_r4). Nonsense variants in NEK1 are expected to be pathogenic. This variant is interpreted as pathogenic. -
