[Edit]
It doesn't *cause* birth defects, but it improves your chance of having a child with birth defects. If you're not related, you have a 3-7% chance of giving birth to a child with defects. If the parents are siblings the probability rises up thrice, to something like 51%. And if those siblings have a family history of genetic diseases, it's highly likely that a child would suffer from any or all of these genetic diseases.
