Länk - Autism har stark ärftlig komponent
Although the cause of autism is not yet clear, studies of twins have shown that genes play a major role. It is likely that variations in many genes, influenced by environmental factors, interact during brain development to cause vulnerability to the disease. These genes have yet to be identified. Several candidates, including CNTNAP2, have been suggested. The assertion that the CNTNAP2 gene appears to be involved is strengthened by the fact that each of the different analytical approaches the researchers used in this study led to the same conclusion.
