Hypoacetylaspartia, also known as N-acetylaspartate (NAA) deficiency is an extremely rare autosomal recessive inborn error of metabolism (IEM) caused by a mutation in the NAT8L gene. This gene encodes the N-acetylaspartate synthase protein, which catalyzes the formation of N-acetyl-L-aspartate from L-aspartate and acetyl-CoA, with CoA and a hydrogen ion being byproducts. This reaction occurs as part of the aspartate metabolism pathway. This disorder is characterized by a deficiency of NAA in the brain, as shown by magnetic resonance spectroscopy (MRS). Symptoms of the disorder include microcephaly, developmental delays, ataxia and seizures, which have been shown to worsen the ataxia. So, only one patient has been diagnosed with Hypoacetylaspartia.
