Is it true that U.S. Doctors Link Gene to Childhood Asthma?
BOSTON (Reuters) – A defective gene appears to contribute to most cases of childhood asthma, a finding that could lead to a better understanding of allergies, U.S. researchers reported on Wednesday. The gene may control some of the signaling in the immune system, the researchers reported in the New England Journal of Medicine. The defective version causes that system to go awry, producing an overreaction.
