Genes affected

NEK9 (HGNC:18591): (NIMA related kinase 9) This gene encodes a member of the NimA (never in mitosis A) family of serine/threonine protein kinases. The encoded protein is activated in mitosis and, in turn, activates other family members during mitosis. This protein also mediates cellular processes that are essential for interphase progression.

ZC2HC1C (HGNC:20354): (zinc finger C2HC-type containing 1C) Predicted to enable metal ion binding activity. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -16 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0072137117).
• BP6: Variant 14-75091355-C-T is Benign according to our data. Variant chr14-75091355-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 717455.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0031 (472/152342) while in subpopulation AFR AF= 0.0106 (441/41572). AF 95% confidence interval is 0.00979. There are 1 homozygotes in gnomad4. There are 227 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
