Researchers find gene linked to asthma: "'What makes our find so special is that we found an individual immunological gene that seems to be directly connected to the risk of developing asthma,' the head of the research team, Torben Kruse, said.

Kruse said the discovery is likely to lead to earlier detection and better treatment. But he said the causes of asthma are complicated and include environmental factors. "
