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]

Collection Method:clinical testing

The NEK1 c.379C>T variant is predicted to result in premature protein termination (p.Arg127*). This variant was reported in the homozygous state in an individual(s) with short rib-polydactyly syndrome, Majewski type (Thiel et al 2011. PubMed ID: 21211617; El Hokayem J et al 2012. PubMed ID: 22499340). However, the parents and siblings of the probands, who were heterozygous for this variant, were not reported to have any features of amyotrophic lateral sclerosis (ALS, Thiel et al 2011. PubMed ID: 21211617). This variant is reported in 0.0061% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/4-170511894-G-A). Nonsense variants in NEK1 are expected to be pathogenic and there have been protein-truncating variants upstream and downstream of this variant reported in individuals with ALS (HGMD, ClinVar). This variant is interpreted as likely pathogenic and may display incomplete penetrance. -
