Simeon Bennet, of Bloomberg News, reports that Australian scientists have isolated 35 genes that are linked to chronic fatigue syndrome (CFS). Researchers tested 30,000 genes from 15 mononucleosis patients. A link between mononucleosis and CFS had previously been established.

Although not absolute that the 35 isolated genes will yield the one gene they are looking for, the scientists feel confident they are close to finding the key to unlock the CFS mystery. The researchers also feel that they have enough evidence to show that CFS is separate from mood disorders or depression and is definitely not psychological.
