In 1994 I was diagnosed with celiac disease, which led me to create Celiac.com in 1995. I created this site for a single purpose: To help as many people as possible with celiac disease get diagnosed so they can begin to live happy, healthy gluten-free lives. Celiac.com was the first site on the Internet dedicated solely to celiac disease. In 1998 I created The Gluten-Free Mall, Your Special Diet Superstore!, and I am the co-author of the book Cereal Killers, and founder and publisher of Journal of Gluten Sensitivity.

The genetic markers associated with celiac disease are:

  • HLA DQalpha *0501
  • HLA DQbeta *0201

More than 90% of patients with celiac disease have these markers. Negative tests for these markers in conjunction with negative serum antibody tests suggest an absence of celiac disease. However, positive tests for the genetic markers do not necessarily mean that the patient has celiac disease. In conclusion, genetic markers can be used as a test to exclude celiac disease as a diagnosis.
