Genetic factors that may cause ASD possible genetic mutations that cause autism Another possible cause of autism is genetic mutations in the genome of the affected person.
Some people with ASD have a known difference, such as a genetic condition. If the lack of microbiome diversity is a symptom, not a cause, there's not much they can do to address autism's roots.

[4],[5] Regardless, researchers and worried parents alike have speculated about causes of autism, and the issue has been widely studied. Autism spectrum disorder has both genetic and environmental origins.
