The children often show a wide range of cognitive, emotional and behavioral abnormalities. Autism always begins before the age of three, the male to female ratio is about 4 :1, it often accompanied by significant mental retardation. In recent years, the incidence rate of childhood autism showed an increasing trend. The latest epidemiological survey of the prevalence of autism in the United States is about 9.1 ‰. The widely accepted Common Disease-Common Variant hypothesis predicts that the risk alleles in ASDs and other complex disorders will be common in the general population. Since the early onset of the disease, it is difficult for early identification, and there is no cure or method can completely cu
