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.

Nephronophthisis 9 Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 04, 2023This sequence change creates a premature translational stop signal (p.Arg127*) in the NEK8 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in NEK8 are known to be pathogenic (PMID: 23418306, 26967905). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This premature translational stop signal has been observed in individual(s) with NEK8-related conditions (PMID: 26967905). ClinVar contains an entry for this variant (Variation ID: 490183). For these reasons, this variant has been classified as Pathogenic. -
