I'll answer that a different way. There are phenocopies of thalidomide embryopathy, so there are genetic conditions that look very similar to thalidomide embryopathy, such as Holt-Oram syndrome, and Okihiro syndrome. We can now genetically test for those, so we can now discount that they're thalidomide. There's a possibility that, in the past, some people may have had those conditions and it had been thought to have been thalidomide. There has been a lot of research looking at the mechanisms of thalidomide, and there are a couple of genetic targets. There's a gene called cereblon, which is ubiquitin ligase, that takes away gene function in cells. That's been show to be—
