Do patients with inflammatory bowel disease want genetic testing?
GROUND: Inflammatory bowel disease (IBD) is a complex genetic disorder characterized by nonmendelian inheritance, incomplete penetrance, and disease susceptibility but not disease certainty. Genotype and phenotype associations are described, but the level of interest of patients with IBD in genetic testing for themselves or at-risk family members remains unknown. Thus, the goal of this study was to assess the interest of patients with IBD in genetic testing and their willingness to accept the uncertainty inherent in complex genetics. MATERIALS AND METHODS: Consecutive outpatients with IBD were recruited to complete a 57-item self-administered survey. The survey included a layperson explanation of the limits of IBD genetics. A 5-point Likert scale was used to determine willingness to undergo genetic testing to determine diagnosis, prognosis, and treatment; to help their family; and to advance medical knowledge. The IBD Questionnaire, a validated measure of the health status attitudes of
