Abstract:
Inborn errors of immunity (IEI) are a heterogeneous group of genetic disorders affecting immune function, often presenting with diverse gastroenterological symptoms that pose diagnostic challenges. The latest classification developed by the International Union of Immunological Societies Experts Committee includes 582 IEI disease entities. Unfortunately, 70-80% of cases are still not recognized and do not enter the patient registers. Most cases are also diagnosed too late. This review explores the epidemiology, classification, symptoms, diagnostics, and treatment of gastrointestinal involvement in IEI.

Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
