Priorities from my perspective would be follow up studies as required to establish some important finding. What great research projects so far only need an independent follow up study to "put them on the books"? I have a very poor memory, but isn't there a need for another 2 day exercise test, or one like the Lights did? It seems to me there are a number of important findings that just need the all important larger, independently run study to make them official.
Let's think like scientists--if we could be excellent scientists reviewing the whole field of literature so far, what are the glaring gaps in knowledge? And I am not talking about THE CAUSE. If only they would give that pursuit up and put money and attention on the abnormalities in our system, biomarkers, and treatments. And when I say treatment, I do not mean THE TREATMENT, as if there is one master treatment which might solve all our problems, but better treatments for the various organ systems affected.
However, the aspects which come to mind which do seem particularly important have to do with the mitochondrial function, the methylation problem, and then the low immune and endocrine systems. Maybe I should say immune system abnormalities because there seems to be both inflammation where it doesn't belong and a lack of immune functioning where it is needed.
There are going to be limited funds and projects supported so the ones chosen had better be as useful as possible. What matters most now, what is achievable now, what are the next steps?
