Variant summary
Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PVS1PM2PP5_Moderate
The NM_178170.3(NEK8):c.743del(p.Pro248HisfsTer56) variant causes a frameshift change. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Pathogenic (★). Synonymous variant affecting the same amino acid position (i.e. P248P) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

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 submitter | clinical testing | Invitae | Feb 06, 2017 | This sequence change deletes 1 nucleotide from exon 5 of the NEK8 mRNA (c.743delC), causing a frameshift at codon 248. This creates a premature translational stop signal (p.Pro248Hisfs*56) and is expected to result in an absent or disrupted protein product. While this particular variant has not been reported in the literature, loss-of-function variants in NEK8 are known to be pathogenic (PMID: 23418306). For these reasons, this variant has been classified as Pathogenic. - |
