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 c.2730_2733delCAAA likely pathogenic variant in the NEK1 gene has been published in association with short-rib polydactyly syndrome type II also known as Majewski Syndrome (Zhang et al., 2017). It is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The c.2730_2733delCAAA variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016). In summary, this variant is likely pathogenic; however, the possibility that it is benign cannot be excluded. -
