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]

PreventionGenetics, part of Exact Sciences

Significance:Likely pathogenic

Review Status:no assertion criteria provided

Collection Method:clinical testing

The NEK1 c.481C>T variant is predicted to result in premature protein termination (p.Arg161*). This variant has been reported in one individual with amyotrophic lateral sclerosis (ALS, Table S4, Black et al. 2016. PubMed ID: 28089114). Protein-truncating variants upstream and downstream of this variant have been reported to be pathogenic (HGMD, ClinVar). However, the c.481C>T variant has been reported in 20 and 80 heterozygous individuals in gnomAD v2 and v4, respectively. Protein-truncating variants in NEK1 are expected to be pathogenic. At this time, we interpret this variant as likely pathogenic. -

Apr 30, 2022

Labcorp Genetics (formerly Invitae), Labcorp

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

ClinVar contains an entry for this variant (Variation ID: 266058). This premature translational stop signal has been observed in individual(s) with NEK1-related conditions (PMID: 28089114, 29431110). This variant is present in population databases (rs202115635, gnomAD 0.1%). This sequence change creates a premature translational stop signal (p.Arg161*) in the NEK1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in NEK1 are known to be pathogenic (PMID: 22499340, 29068549). For these reasons, this variant has been classified as Pathogenic. -
