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 Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.2796484).

The c.2854G>A (p.E952K) alteration is located in exon 22 (coding exon 22) of the NEK9 gene. This alteration results from a G to A substitution at nucleotide position 2854, causing the glutamic acid (E) at amino acid position 952 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
