Genes affected
NEK8 (HGNC:13387): (NIMA related kinase 8) This gene encodes a member of the serine/threionine protein kinase family related to NIMA (never in mitosis, gene A) of Aspergillus nidulans. The encoded protein may play a role in cell cycle progression from G2 to M phase. Mutations in the related mouse gene are associated with a disease phenotype that closely parallels the juvenile autosomal recessive form of polycystic kidney disease in humans.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 27, 2024The c.22C>G (p.R8G) alteration is located in exon 1 (coding exon 1) of the NEK8 gene. This alteration results from a C to G substitution at nucleotide position 22, causing the arginine (R) at amino acid position 8 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Nephronophthisis 9 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 27, 2023This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 8 of the NEK8 protein (p.Arg8Gly). This variant is present in population databases (rs199621354, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with NEK8-related conditions. ClinVar contains an entry for this variant (Variation ID: 943025). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
