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.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.014174402).

BP6

Variant 17-28738685-A-C is Benign according to our data. Variant chr17-28738685-A-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 539144.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00175 (267/152290) while in subpopulation AFR AF = 0.00616 (256/41560). AF 95% confidence interval is 0.00554. There are 1 homozygotes in GnomAd4. There are 126 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 2 AR,AD gene
