Here's How to Prevent Atopic Dermatitis That's Taking Over

The Genetic Role in Atopic Dermatitis

Research indicates that atopic diseases, including AD, have a genetic component. Several genes have been associated with the probability of getting AD. Variants of the gene called FLG have been found to be particularly linked, possibly because they influence the skin’s barrier function.

Besides, relatives of people with AD are disproportionately likely to develop the condition. If one parent has AD, asthma, or hay fever, there's about a 50 percent chance their child will have at least one of these diseases. With two affected parents, this risk increases.
