Autism Spectrum Disorder (ASD) is a common neurodevelopmental disorder affecting approximately one in every 100 children when mild cases are included. The risk of autism is higher in individuals with a family history of autism compared to the general population. Research indicates that the prevalence of autism in siblings of a child with ASD is approximately 3%. Consanguineous marriages are also considered a risk factor for autism. While a significant percentage of autism cases have genetic components, autism cannot be defined as a directly hereditary disease solely dependent on a single genetic factor; it is generally believed to result from a complex interaction of environmental and genetic factors.
