KAT6B (Lysine Acetyltransferase 6B): KAT6B is a gene that codes for a histone acetyltransferase involved in chromatin remodeling and gene regulation. It plays crucial roles in development, cell cycle regulation, and DNA repair. Mutations in KAT6B are associated with rare genetic disorders characterised by skeletal abnormalities and developmental delays, including Genitopatellar and Ohdo syndromes.
