Genes affected

ZC3H12B (HGNC:17407): (zinc finger CCCH-type containing 12B) The protein encoded by this gene belongs to a family of CCCH-type zinc finger proteins that are involved in the proinflammatory activation of macrophages. The exact function of this family member is unknown, but it is thought to function as a ribonuclease. [provided by RefSeq, May 2010]

LAS1L (HGNC:25726): (LAS1 like ribosome biogenesis factor) Enables RNA binding activity. Predicted to be involved in maturation of 5.8S rRNA and maturation of LSU-rRNA. Located in membrane. Part of MLL1 complex. Implicated in Wilson-Turner syndrome. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.16683227).

The c.1606A>C (p.K536Q) alteration is located in exon 5 (coding exon 5) of the ZC3H12B gene. This alteration results from a A to C substitution at nucleotide position 1606, causing the lysine (K) at amino acid position 536 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
