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 -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.031443715).

Collection Method: clinical testing

The c.368A>G (p.D123G) alteration is located in exon 5 (coding exon 4) of the ZNF81 gene. This alteration results from a A to G substitution at nucleotide position 368, causing the aspartic acid (D) at amino acid position 123 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
