One may also ask, who investigated the genetic basis of autism through twin studies?
The first twin study to report evidence for familiality in autism, by Folstein and Rutter in 1977, investigated the concordance of autism in a small sample of 11 monozygotic twins (MZ) and 10 dizgyotic twins (DZ) (Folstein and Rutter, 1977).
How do you determine the severity of autism?

Autism has been linked to birth defect agents acting during the first eight weeks from conception, though these cases are rare.Who is at high risk for autism?
Children who have a sibling with ASD are at a higher risk of also having ASD. ASD tends to occur more often in people who have certain genetic or chromosomal conditions, such as fragile X syndrome or tuberous sclerosis .What is the number one cause of autism?
There is no known single cause for autism spectrum disorder, but it is generally accepted that it is caused by abnormalities in brain structure or function. Brain scans show differences in the shape and structure of the brain in children with autism compared to in neurotypical children.What is linked to autism?
Genetics. Several different genes appear to be involved in autism spectrum disorder. For some children, autism spectrum disorder can be associated with a genetic disorder, such as Rett syndrome or fragile X syndrome. For other children, genetic changes (mutations) may increase the risk of autism spectrum disorder.How can you detect autism?
Diagnosing autism spectrum disorder (ASD) can be difficult, since there is no medical test, like a blood test, to diagnose the disorders. Doctors look at the child's behavior and development to make a diagnosis. ASD can sometimes be detected at 18 months or younger.How common is autism?

Can you be tested for autism gene?
No. A genetic test cannot diagnose or detect autism. That's because myriad genes along with environmental factors may underlie the condition. Roughly 100 genes have clear ties to autism, but no single gene leads to autism every time it is mutated.Can a child outgrow autism?
Summary: Research in the past several years has shown that children can outgrow a diagnosis of autism spectrum disorder (ASD), once considered a lifelong condition. In a new study, researchers have found that the vast majority of such children still have difficulties that require therapeutic and educational support.Does autism get better?
