Understanding and Diagnosing Allergic Disease in Twins
- Conditions
- Allergies
- Interventions
- Other: No Intervention
- Registration Number
- NCT01613885
- Lead Sponsor
- Stanford University
- Brief Summary
The purpose of this study is to gain better understanding of how the immune system works in twins with and without allergic disease. Healthy volunteers are not specifically targeted. Healthy non-allergic study participants may be found through the course of evaluation for the presence of allergies.
- Detailed Description
The purpose of this study is to study the genetic control and gain better understanding of how the immune system works in twins with and without allergic disease. Although healthy volunteers are not specifically targeted, they might be identified when non-allergic study participants are found through the course of evaluation for the presence of allergies.
