Genes affected

ZNF789 (HGNC:27801): (zinc finger protein 789) Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Located in nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ZNF394 (HGNC:18832): (zinc finger protein 394) The protein encoded by this gene is a zinc finger protein that inhibits the transcription of mitogen-activated protein kinase signaling pathways. The encoded protein may be involved in cardiac function. [provided by RefSeq, Sep 2016]

The c.911A>C (p.Q304P) alteration is located in exon 5 (coding exon 4) of the ZNF789 gene. This alteration results from a A to C substitution at nucleotide position 911, causing the glutamine (Q) at amino acid position 304 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
