It seems there's a new study out. Some of the authors might not be very popular anymore among some parts of our community... Nevertheless, i think it might be interesting. But it shouldn't distract from HGRV, in my opinion.
But who knows, maybe it will all be part of the explanation, genetic predisposition, HGRV and coinfections and other factors like toxins, lifestyle, vaccinations, etc. Just speculating, of course.
Delete, if there's already a thread.

Abstract (provisional)
Background
Chronic Fatigue Syndrome (CFS) came to attention in the 1980s, but initial investigations did not find organic causes. Now decades later, the etiology of CFS has yet to be understood, and the role of genetic predisposition in CFS remains controversial. Recent reports of CFS association with the retrovirus xenotropic murine leukemic virus-related virus (XMRV) or other murine leukemia related retroviruses (MLV) might also suggest underlying genetic implications within the host immune system.
Methods
We present analyses of familial clustering of CFS in a computerized genealogical resource linking multiple generations of genealogy data with medical diagnosis data of a large Utah health care system. We compare pair-wise relatedness among cases to expected relatedness in the Utah population, and we estimate risk for CFS for first, second, and third degree relatives of CFS cases.
Results
We observed significant excess relatedness of CFS cases compared to that expected in this population. Significant excess relatedness was observed for both close (p<0.001) and distant relationships (p = 0.010). We also observed significant excess CFS relative risk among first (2.70, 95% CI: 1.56-4.66), second (2.34, 95% CI: 1.31-4.19), and third degree relatives (1.93, 95% CI: 1.21-3.07).
Conclusions
These analyses provide strong support for a heritable contribution to predisposition to Chronic Fatigue Syndrome. A population of high-risk CFS pedigrees has been identified, the study of which may provide additional understanding.
