Abstract: Researchers have known that genes contribute to autism since the 1970s, when a team found that identical twins often share the condition.Since then, scientists have been racking up potential genetic culprits in autism, a process that DNA-decoding technologies have accelerated in the past decade.As this work has progressed, scientists have unearthed a variety of types of genetic changes that can underlie autism.The more scientists dig into DNA, the more intricate its contribution to autism seems to be. How do researchers know genes contribute to autism?Since the first autism twin study in 1977, several teams have compared autism rates in twins and shown that autism is highly heritable.When one identical twin has autism, there is about an 80 percent chance that the other twin has it too.The corresponding rate for fraternal twins is around 40 percent.
