I would go for genetic testing, but certainly physical examination. I don't see how you can reject someone without a physical examination.
The one key factor, though, is going to be what are the conditions that have been reported in some of the thalidomide victims, such as ventricular septal defect in the heart, the so-called hole in the heart. That is very common in society in general, but it does occur in these people exposed to thalidomide, so what are you going to say? If you compensated everyone who had a VSD, you'd have a huge number of people coming to you. That, I think, is the difficulty.
