Q: Does DNA or genetics have anything to do with asthma and eczema in children? And why does it skip generations?
A: The simplest answer is that DNA has everything to do with what we’re talking about, and it doesn’t really skip generations. When we talk about allergic disease ranging from eczema to hay fever and allergies and asthma, there really is a genetic predisposition to what families will carry. The true risk is actually any history of atopic disease. We are seeing fewer generations of people who didn’t have histories of hay fever or allergies in the past develop these diseases.
