N-acetylaspartate deficiency (NACED) is a very rare disorder characterized by the absence of brain N-acetylaspartate (NAA) with truncal ataxia, marked developmental delay, seizures, and secondary microcephaly. NAA is a brain-specific molecule, that is essentially present in neurons. The mutation in NAT8L has been reported in the patient with NACED. It has been suggested that NAT8L, a neuron-specific protein, is responsible for NAA synthesis.
