How do genetics influence food allergies?

Collect and analyze DNA information from blood samples, along with health records and survey responses to determine whether there is a genetic component to the following aspects of food allergies:

1. Predisposition to the development of allergies (who, at what age, to what degree of severity)

2. Triggers of allergic reactions

3. Validity of allergy testing

4. Response to treatment

5. Predisposition to outgrow allergies
