Autism spectrum disorder (ASD) is a social interaction and communication impairment, associated with repetitive behaviors and interests. ASD has a high worldwide prevalence of about 1-1.5%. ASD is usually accompanied with heterogeneous phenotypic comorbidities, such as epilepsy and intellectual disability (ID). Twin studies suggest a high genetic contribution to ASD etiology, and several well-known rare genetic disorders are associated with ASD with high susceptibility contribution risk at about 0.5-1% of ASD cases. Moreover, several environmental factors and chromosomal abnormalities may increase the risk; the estimated known ASD-related genetic etiology is identifiable in about 25% of all ASD cases. Nevertheless, in about 75% of ASD cases the genetic etiologies remain elusive. The occurrence of ASD in the Middle East is not clear and there is a need to fill the gap in its clinical and genetic characterization in the Arab populations.
