Thank you.
My question is for Mr. Vargesson. Mr. Vargesson, you've talked a bit about genetics and the fact that it can actually go a long way to disprove other causes, and that looking at other offspring or siblings can also be used in order to see the impact that thalidomide may have had on a victim. Given these statements, can you conclude that extensive testing and observation can all but disprove other causes in the case of thalidomide victims, let's say, someone with multiple issues, a genetic test, and normal children, for example?
