Question

Quizplus · Accepted Answer

Although there is ongoing research, currently there is no clear causal relationship between a specific genetic abnormality and the occurrence of autism. While environmental factors may contribute, genetics is thought to play a major role. The claim that immunizations or early childhood infections cause autism has been thoroughly debunked by scientific evidence. The notion that the cause will be found in a specific area of the X chromosome is outdated and not supported by current research. The idea that family configuration is the primary cause is not supported by scientific evidence.
