Abstract: 

Researchers have known for years that when one identical twin has autism, the other is also likely to be diagnosed with it - evidence that autism likely has a genetic component. Recent studies support that theory. Researchers at Kennedy Krieger Institute studied 277 pairs of twins and found that when one identical twin had the disorder, the other developed it 88 percent of the time; for fraternal twins, that figure was 31 percent.
