Genetic Testing For Autism What Do You Think Causes Autism?

What do you think causes autism? - genetic testing for autism

What do you think causes autism? I have many different opinions on whether it belongs to the environment caused by vaccines or genetics. What do you think is the cause? also why so many autistic children today? I'm 23 and I've never seen so many people my age it is. and there is a genetic test of a person to see if they are more likely a child with autism?
