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 variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.003%). In silico tool predictions suggest damaging effect of the variant on gene or gene product (3Cnet: 0.92). Same nucleotide change resulting in same amino acid change has been previously reported to be associated with NEK1 -related disorder (ClinVar ID: VCV000446674 / PMID: 29068549). The variant has been reported to be in trans with a pathogenic variant as either compound heterozygous or homozygous in at least one similarly affected unrelated individual (PMID: 29068549 / 3billion dataset). Therefore, this variant is classified as Likely pathogenic according to the recommendation of ACMG/AMP guideline. -
