Genes affected

KAT2B (HGNC:8638): (lysine acetyltransferase 2B) CBP and p300 are large nuclear proteins that bind to many sequence-specific factors involved in cell growth and/or differentiation, including c-jun and the adenoviral oncoprotein E1A. The protein encoded by this gene associates with p300/CBP. It has in vitro and in vivo binding activity with CBP and p300, and competes with E1A for binding sites in p300/CBP. It has histone acetyl transferase activity with core histones and nucleosome core particles, indicating that this protein plays a direct role in transcriptional regulation.

The c.211G>A (p.G71S) alteration is located in exon 1 (coding exon 1) of the KAT2B gene. This alteration results from a G to A substitution at nucleotide position 211, causing the glycine (G) at amino acid position 71 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
