[1] Attempts have been made to incorporate the known genetic and environmental causes into a comprehensive causative framework. [ 2 ]

Air pollution can negatively affect a pregnancy resulting in higher rates of preterm births, growth restriction, and heart and lung problems in the infant. [22] Compounds such as carbon monoxide, sulfur dioxide and nitrogen dioxide all have the potential to cause serious damage when inhaled by an expecting mother. [23]
The amygdala, cerebellum, and many other brain regions have been implicated in autism. [15]Unlike some brain disorders which have clear molecular hallmarks that can be observed in every affected individual, such as Alzheimer's disease or Parkinson's disease, autism does not have a unifying mechanism at the molecular, cellular, or systems level.
Consequently, any changes in folate levels or folate metabolism could significantly impact DNA methylation and contribute to what causes autism. This idea is what makes folate pathways a potential predictor of ASD because genetic polymorphisms of the folate pathway could have different effects on DNA methylation.
Autism spectrum disorder [a] (ASD), or simply autism, is a neurodevelopmental disorder "characterized by persistent deficits in social communication and social interaction across multiple contexts" and "restricted, repetitive patterns of behavior, interests, or activities".
