As a side note there is the following study CFS/me which might be of interest
"We aim to find genetic causes of why people become ill with myalgic encephalomyelitis (ME) / Chronic Fatigue Syndrome (CFS) with our ground-breaking research. Take part from your home"
Sorry, but they will not find it. At best ME/CFS has a polygenic cause but unless they are also testing for nutrient deficiencies this will come to nothing.
The cure can only come from personalized medicine, looking at the individual, not looking for a common cause.
But surely this is a treasure trove of data? Sure the research is aiming to find some sort of common ground, but it still would be possible to use the raw data later on
