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]

The c.907G>A (p.G303S) alteration is located in exon 5 (coding exon 3) of the ZNF420 gene. This alteration results from a G to A substitution at nucleotide position 907, causing the glycine (G) at amino acid position 303 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
