@Alvin2, I agree with you, although there are some information from the rather limited tests of SNP´s or CYP´s that might be useful. I think whatever the cause of ME/CFS will be proved to be, we still have individual genetic variations with impact on our health.
As an example, the subgroup that Wilfred De Vega and his research group found out about a genetic sensitivity to glucocorticoids among a significant group of PWME is quite interesting and important I think.
@Valentijn, thanks. Would you recommend any other site? I recall that some other program has been recommended on the forum, but maybe noone is reliable.
Edit: Thanks
