ppodhajski - If in fact you understand the genetic causation of ME, and can explain it from any promethease report, that would be a huge discovery.
I think the test would be this: If I gave you 10 promethease files, 5 of whom have ME, 5 of whom are healthy controls, can you successfully classify them based on the genetics alone?
If so, then I will be very impressed. I think it's more likely though that you are able to spot some supposed risk factors in any given promethease file that would also be present in many healthy controls.
Even if you could list an algorithm for genetically ruling out ME in patients, that would be incredibly useful.
Any test should be something you can describe clearly in writing and should be repeatable by others, so you should be able to explain what you are looking for in the promethease files.
I have some very strong suspicions about roles of some genes in the pathogenesis of ME, but I don't think that it's a completely homogeneous disease or that it can be predicted with certainty from a single 23andme dataset, or even a complete genome sequence. No one has yet described any genomic test that either rules out or rules in all ME patients.
Furthermore, there have been several twin studies in ME. In many cases, one twin gets ME, and the other does not. Thus, genetics is clearly not the only relevant factor. I do think there is a predisposition, at least in some cases, but that is true of many illnesses. e.g. There is a form of colorectal cancer that is largely caused by the APC gene (not 100%, cancer always requires a random event, whether in the most or least predisposed to it). Most colorectal cancer, however, is not connected to the APC gene. So some people are born with a high risk for it, and others with a low one - but neither is a guarantee of outcome.
