ASD has a high prevalence of 1 in every 68 children, with boys 4.5X more likely to have the disorder. Currently, scientists do not know the exact cause of autism. However, it is agreed upon that the underlying cause is highly likely to be influenced by genetic heritability.3,4,16 ASD research is important for several reasons. The most apparent reason is the dramatic increase in the occurrence in the last 20 years. Other reasons are economic costs of children with ASD, burdensome responsibilities, and emotional hardships on parents, family members, and communities. Factors contributing to the increase could very likely be caused by our better understanding of the disorder and diagnosis due to human genome sequencing technology and other scientific research.

The genetic architecture of ASD is comprised of a variety of rare mutations. These mutations include monogenic conditions involving autistic symptoms. Furthermore, single nucleotide variants and de novo copy number variants add to disease susceptibility.
