Study of Gut Microbiota in Primary Immune Deficiency, Possibly Associated With Inflammatory Bowel Disease

The investigators will include patients (adults or children), with Primary Immune Deficiency (CGD, XIAP or TTC7A deficiencies), and they will collect feces samples from them. In parallel, as control groups, patients with no inflammatory bowel disease and no primary immune deficiency will be included, and also patients suffering from Crohn's disease without known primary immune deficiency. The laboratory collaborators will then realize analyzes on the microbiota collected for all patients. The study team will then analyze the microbiota composition of the different types of patients, and try to identify some factors, associated with the appearance of an inflammatory disease on these patients.
