<<Disclaimer: Verify this information before applying it to your situation.>> I am a Dutch PhD-student working on the genetics of CD. At the moment I am collecting blood samples from affected Dutch brothers and sisters and their parents. I would like to ask if there are patients, who have at least one brother or sister with CD, who want to participate in this project, preferably Dutch, Belgian en German patients. Also, if there are doctors who are consulting affected siblings, please contact me.
