Autism Spectrum Disorder is one of the most complex developmental disorders with a strong genetic impact. In recent years, researchers have increasingly linked effects of central cholinergic system dysfunction to autism-related cognitive and behavioral abnormalities at the molecular pathological level. Results from autopsy studies, clinical cases and animal experiments revealed that aberrant muscarinic acetylcholine receptors have a strong relationship with autism. In behavioral studies using mouse models, the variations of CHRM3 gene, which encodes the muscarinic acetylcholine receptor subtype III receptor, can cause autistic phenotypes such as cognitive impairment and stereotypic behavior. Accordingly, in-depth functional understanding of CHRM3 gene may have important implications to further explain the characteristics and mechanisms of autistic behavior and may potentially provide new ideas and methods for the development of educational programs for autistic children.

Key words: autism spectrum disorder, CHRM3 gene, clinical features, animal models
