Genes affected

ZNF420 (HGNC:20649): (zinc finger protein 420) The protein encoded by this gene is a KRAB-type zinc finger protein that negatively-regulates p53-mediated apoptosis. Under stress conditions, the encoded protein is phosphorylated by ATM and dissociates from p53, which activates p53 and initiates apoptosis. [provided by RefSeq, Jul 2016]

ZNF585A (HGNC:26305): (zinc finger protein 585A) Predicted to enable DNA-binding transcription activator 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. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Nov 12, 2021

The c.821C>T (p.T274I) alteration is located in exon 5 (coding exon 3) of the ZNF420 gene. This alteration results from a C to T substitution at nucleotide position 821, causing the threonine (T) at amino acid position 274 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
