Girls may be more resistant to autism than boys, according to a new study that determined girls have to suffer more genetic mishaps than boys to develop the disorder.

Scientists say everyone carries a certain number of duplications or deletions to DNA. But, if you accumulate enough of them, those variants may lead to autism and other conditions.

In studies in the journal Neuron, it was determined that it takes more damage to the genome to lead to autism in girls than in boys. That may explain why boys are four times more likely to have autism than girls.
