Hi, thanks for the link. Me a learner 2 - reader beware! Neil McGregor seems to have identified ----- potentially significant variations in the genes of people with ME/CFS. From what I can see the link you provide relates to the publication below and, as far as I know, it's about --- potentially significant variations in the genes of people with ME/CFS. Don't know if they've found the same potentially significant variations. If you look at the information regarding the "NIH Funded ME/CFS Research Centers"; you see that Hanson and Lipkin are looking at gene expression, so it's still the focus of research.
