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]

ZC2HC1C Gene-Disease associations (from GenCC):

• neurodevelopmental disorder

  Inheritance: AR Classification: LIMITED Submitted by: Ambry Genetics

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.32).
