The goal of this observational study is to investigate the genetic and epigenetic mechanisms that may contribute to the development of Autism Spectrum Disorder (ASD) in individuals of different age groups. The study aims to explore how genetic variants and environmental factors interact to influence the risk of ASD. The main questions it aims to answer are: * Which genetic variants are most strongly associated with the development of ASD? * How do environmental factors, such as prenatal exposure, influence these genetic risks? * Can the combination of genetic and epigenetic data improve early detection or intervention strategies for ASD? Participants will: * Provide biological samples for genetic and epigenetic analysis. * Complete detailed questionnaires regarding environmental exposures and family history. * Participate in clinical assessments to evaluate the severity of ASD symptoms. Researchers will compare genetic and environmental data between individuals with ASD and those without the disorder to understand how these factors may contribute to the risk of ASD. This multi-center study will take place across several universities and hospitals in Türkiye, focusing on the potential interplay between inherited genetic factors and environmental influences.
