The genetic testing that's available right now is for only a few conditions, and these are phenocopies of thalidomide, such as how arms intergrow, and a few others. These are limb reduction deformities, and you can use those definitely to say, “Yes, this is not thalidomide.” If a patient has a family history of abnormalities, then it's probably genetic; it's not thalidomide. If they don't have that and they have a collection of problems, then, yes, you have to consider there's a possibility.
