A DEFENCE against manic depression may be written in our genes, scientists say. Edward Ginns and his colleagues at the National Institute of Mental Health near Washington DC looked at the genes of people from families with a genetic predisposition to manic depression. Those who did not develop the disease, despite their high risk, had similarities in one region on chromosome 4. This may contain a gene that protects against the disorder (Proceedings of the National Academy of Sciences, vol 95, p 15 531). This is the first evidence of a beneficial gene linked to a behavioural disorder. “We were really excited,” says Ginns. Understanding how the gene offers protection could lead to new drugs for depression that mimic its effect,
