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

Mar 02, 2023

The c.1622C>T (p.A541V) 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 1622, causing the alanine (A) at amino acid position 541 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
