From: Genetics of glutamate and its receptors in autism spectrum disorder

Mutations or disruptions in genes optimal for neuronal migration, synapsis, and normal functioning of glutamate receptors can cause neuronal excitability, altered brain volume, and impaired long-term LTP and LTD that lead to various autism-related deficits. MZ marginal zone, CP cortical plate, IZ intermediate zone, SVZ subventricular zone, VZ ventricular zone, LTP long term potentiation, LTD long term depression.
