Genes affected

ZNF746 (HGNC:21948): (zinc finger protein 746) Enables DNA-binding transcription repressor activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and ubiquitin protein ligase binding activity. Involved in negative regulation of transcription by RNA polymerase II; positive regulation of neuron death; and positive regulation of transcription by RNA polymerase II. Located in cytosol and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

The c.1433C>A (p.A478E) alteration is located in exon 7 (coding exon 7) of the ZNF746 gene. This alteration results from a C to A substitution at nucleotide position 1433, causing the alanine (A) at amino acid position 478 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
