LONDON (Reuters) - As many as 30,000 different gene variations may underlie schizophrenia and bipolar disease, meaning any kind of quick test to predict either disease is a long way off, scientists said on Wednesday. Three studies by a multinational group of researchers analyzed the DNA of 10,000 people with schizophrenia, and 20,000 without, and found 30,000 ...

Two huge international studies show that people who lack certain chunks of DNA run a dramatically higher risk of getting schizophrenia, a finding that could help open new doors to understanding and diagnosing the disease. These deletions are rare, each found in less than 1 ...

Scientists have pinpointed genetic variations that make people more likely to get hooked on cigarettes and more prone to develop lung cancer — a finding that could someday lead to screening tests and customized treatments for smokers trying to kick the habit. The discovery by three separate teams of ...
