No. [Technical difficulty—Editor] as I've said before, the competing probabilities in any causality statement that you make. What you can do is to do a genetic test so that you know that this gene causes this kind of problem, and then look at the family history and see whether this has occurred before in the family. Then you're on as a solid ground as you can be to say that the genetic thing was the cause, not the drug.
