Gene clues show which children will grow out of asthma

Roughly half of children with asthma will emerge from it by the time they become young adults -- but until now, no-one knows how to determine who will be the lucky ones.

A gene scorecard may one day help predict which youngsters are likely to grow out of childhood asthma and which will have the disease in adulthood, a study said on Thursday.

Asthma is one of the commonest disorders among children in developed countries and is spreading fast in emerging economies.
