If your child is 18 years of age or younger and has been experiencing chronic diarrhea or abdominal pain for at least 4 weeks, he/she may qualify to participate in this study at a site near you.

If your child is eligible, there is the potential for up to three doctor’s office visits that could include: having the inside of his/her cheeks swabbed to look for common genetic mutations found in CSID patients, taking a breath test, providing a medical history review, and completing a few questionnaires.
