LONDON (Reuters) - Scientists have identified a genetic change that raises a child’s risk of developing asthma, a discovery that may lead to better treatments for one of the most common chronic childhood ailments.The finding adds to further evidence of the role genetics -- rather than environmental factors such as allergies -- play in how children develop asthma, said William Cookson, a researcher at London’s Imperial College’s National Heart and Lung Institute, who coordinated the multinational study.
