New ‘asthma gene’ could lead to new therapies

A gene that is strongly associated with a risk of developing childhood onset asthma was identified by an international team of scientists, whose findings are published today in the journal Nature.

In a genetic study of more than 2,000 children, scientists from the University of Michigan and colleagues from London, France and Germany found genetic markers that dramatically increase a child’s risk for asthma. These markers are located on chromosome 17, and children with this marker had higher levels of a new gene called ORMDL3 in their blood, which occurs in higher amounts in children with asthma. The presence of the disease-associated version of ORMDL3 increases the risk of asthma by 60-70 percent, the study suggests.
