Multi-Center African-American Inflammatory Bowel Disease Study (MAAIS)
Source: ClinicalTrials.gov · Last updated 16 Jan 2026
Brief summary (registry, in English)
The investigators are doing the research to discover genes that cause Inflammatory Bowel Disease (IBD) specifically in the African American population. African Americans with or without Crohn's disease or ulcerative colitis are eligible to join. If you agree to join the study, the investigators will ask for information about your health. The investigators will also ask you to give us a blood sample so that they may discover the genes that cause IBD. The blood sample may be collected at Johns Hopkins or any local facility convenient to you.
