Core Tip

Core tip: Genetic investigation is of fundamental importance describing inflammatory bowel disease (IBD) as a complex disease, as well as in identifying the monogenic disorders that may present with IBD-like features. Using third-generation technology should be leveraged to accelerate the screening and allow the identification of the most rare monogenic defects. Furthermore, the study of genetic variants in monogenic and in sporadic IBD could help unraveling the complex interplay between defective and compensatory immune responses, opening the way to the identification of new targets for therapy.
