Autism Spectrum Disorder Etiology and Circumcision

Current Understanding of ASD Etiology

The American Academy of Child and Adolescent Psychiatry understands that ASD has a complex, multifactorial etiology with strong genetic components and potential environmental factors 1, 2
Genetic factors, including multiple genes, are identified as risk factors for ASD, with a high recurrence risk in siblings (2-10%) and higher concordance in monozygotic twins (70-90%) compared to dizygotic twins (3%) 1, 2, 3
Advanced maternal or paternal age, extremely premature birth (less than 26 weeks gestational age), and family history of learning/language problems and social disability are also identified as risk factors for ASD 2, 3

The American Academy of Pediatrics' early identification guidelines for ASD do not include circumcision as a risk factor, based on evidence from studies such as those published in Pediatrics 4, 6, 7
Clinical genetics evaluation guidelines from the American College of Medical Genetics do not list circumcision among factors to consider when identifying the etiology of ASD, as stated in Genetics in Medicine 5, 8

The American Academy of Child and Adolescent Psychiatry's practice parameters do not mention circumcision as a risk factor for ASD, and standard evaluation for children with ASD should focus on established genetic and environmental factors rather than history of circumcision 1, 2, 5
