Allergies are certainly the result of both genetic and environmental factors, but there is fresh evidence to suggest that at least one major genetic aberration could be behind everything from hay fever to food allergies to asthma.
Allergies — to dust, pet hair or peanuts — are essentially the product of misdirected immune systems, which start to see innocuous objects as potential threats and launch an intensive assault that can translate into sneezing, wheezing, and even potentially fatal seizures.
Now researchers studying the genetics behind the rare tissue disorders Marfan and Loeys-Dietz syndromes have discovered that there may be a common genetic driver behind almost all allergic diseases.
