I have not seen any studies on whether twins are more likely to have an autism spectrum disorder than single-birth children. It is possible that no one has done research on this.
If one identical twin has an autism spectrum disorder, there is approximately a 90% chance that the other identical twin will. They might not have the same autism spectrum disorder or they might have the same disorder at different levels of severity. Many studies show the chance that they both have it if one twin does as somewhere between 82% and 97%.
If the twins are fraternal (non-identical) twins and one has an autism spectrum disorder, the other has about the same chance of having an autism spectrum disorder as non-twin siblings do, which is greater than the chance of having an autism spectrum disorder in a family that does not have any history of it.
