GRIA2 and Alzheimer disease: A comprehensive study on RNA editing in the tissues of post-mortem Alzheimer’s disease (AD) patients reported a reduction in RNA editing activity at various A-to-I sites in the hippocampus, temporal lobe, and frontal lobe [72], and neuronal death in AD has been suggested to be associated with disturbance of RNA editing at the GluA2 Q/R site [73,74].
