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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 04, 2022The c.444A>T (p.K148N) alteration is located in exon 5 (coding exon 4) of the ZNF81 gene. This alteration results from a A to T substitution at nucleotide position 444, causing the lysine (K) at amino acid position 148 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
