Among them are de novo mutations of the lysine-acetyltransferase 6A gene (KAT6A; also known as MYST3 and MOZ; MIM *601408) that cause KAT6A syndrome (Arboleda-Tham Syndrome, autosomal dominant mental retardation 32; MIM # 616268) [6]. Here, KAT6A is linked to autosomal dominant intellectual disability-craniofacial anomalies-cardiac defects syndrome.
