Scientists have identified thousands of genes which appear to play a role in chronic fatigue syndrome (CFS). A team from Glasgow University found a particular pattern of genetic activity among 50 people with the condition. They hope their work, which is still in its early stages, could lead to a diagnostic test and new treatments. CFS - or myalgic encephalomyelitis (ME) - used to be dismissed as “yuppie flu” and has been widely recognised as a disease only in recent years.
