Genes affected

ZNF81 (HGNC:13156): (zinc finger protein 81) This gene encodes a protein that likely functions as a transcription factor. The protein contains an N-terminal KRAB domain and several C2H2-type zinc finger motifs. Mutations in this gene cause an X-linked form of intellectual disability (MRX45). Microduplication of a region of chromosome X including this gene has also been associated with other forms of intellectual disability. [provided by RefSeq, Jul 2017]

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
• BP7: Synonymous conserved (PhyloP=-0.392 with no splicing effect.
