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