Genes affected

CEBPZ (HGNC:24218): (CCAAT enhancer binding protein zeta) This gene belongs to the CBF/Mak21 family. The encoded protein plays a role in cellular response to environmental stimuli through a transcriptional process that involves heat shock factors, conserved DNA elements (heat shock elements or HSEs) and CCAAT boxes. The protein acts as a DNA-binding transcriptional activator and regulates the heat-shock protein 70 (HSP70) promoter in a CCAAT-dependent manner. The protein is also involved in cell growth and differentiation, particularly, hematopoietic differentiation. [provided by RefSeq, Nov 2020]

The c.2458A>C (p.K820Q) alteration is located in exon 10 (coding exon 10) of the CEBPZ gene. This alteration results from a A to C substitution at nucleotide position 2458, causing the lysine (K) at amino acid position 820 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
