Interesting article that highlights some of the latest research on one genetic component of asthma. A bit technical for the lay reader but the take home message is that inherited aspects of asthma are real and under active investigation.

Finally a link that discusses the DNA error and/or inheritance of asthma, as well as what it is not. A bit technical, but still worth reading. I think most everybody will learn something here and the link leaves you with ideas for more searches for additional information if you wish.
