Genetic protection against asthma? Some people have it, according to a new study. According to a story at Forbes, having the gene can cut a person's chance of developing asthma in half compared with those who don't have the gene.
Some doctors think the discovery is interesting, but they don't see it as a breakthrough in what continues to be a mysterious ailment.
But this is only one thread in a very complicated disease, and other experts warn against reading too much into the results. "There are many different causes of the inflammation that is central to asthma," said Dr. Jonathan Field, director of the pediatric allergy immunology clinic at New York University/Bellevue Hospital. "This is another tool in our armamentarium for diagnosis and treatment, but it has to be tempered with further study and clinical evidence."
