Definition:

XMRV is a retrovirus that controversial research has linked to chronic fatigue syndrome. Researchers are also looking into possible links between XMRV and prostate cancer, as well as other conditions.

XMRV stands for:

  • Xenotropic
  • Murine leukemia virus
  • Related
  • Virus

Some researchers believe positive XMRV results in studies were caused by contamination and that XMRV doesn't occur in humans; meanwhile, the researchers behind the original XMRV/chronic fatigue syndrome study stand by their work. If XMRV does occur in people, it would be only the third retrovirus to be discovered in humans.
