Brief Summary:

This study has been set up in order to characterize phenotypes and genotypes of patients with early onset enteropathies.

In that goal, Investigators will collect biological samples (mainly blood) of patients suffering from early onset enteropathies and their healthy relatives.

Condition or disease Intervention/treatment
Inflammatory Bowel Disease Other: Biological sampling

Detailed Description:
This study specifically aims at the genetic analysis of early onset enteropathies with the goal in mind to delineate human pathways necessary to maintain intestinal homeostasis despite the considerable density of microbes colonizing the distal part of the human intestine.

Study Type : Observational
Estimated Enrollment : 346 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Host-Microbiota Interactions Across the Gut Immune System: Characterization of Phenotype and Genotype of Early Onset Enteropathies
Study Start Date : June 2014
Estimated Primary Completion Date : June 2029
Estimated Study Completion Date : June 2029

Group/Cohort Intervention/treatment
Sick patients
Biological sampling of blood for all patients. Biological sampling of saliva, biopsies (skin and endoscopic), feces, for some patients
Other: Biological sampling
Biological sampling including blood, feces, biopsies...
Healthy relatives
Biological sampling of blood for all healthy relatives
Other: Biological sampling
Biological sampling including blood, feces, biopsies...

Primary Outcome Measures :
  1. Increasing the current rate (20%) of genetic characterization of early onset entheropathies [ Time Frame: 15 years ]

    Currently, around 20% of early onset entheropathies are genetically characterized. Investigators want to increase this rate via this research protocol.

    Our long term objective is to characterize phenotypes and genotypes of patients with early onset enteropathies.

Biospecimen Retention:   Samples With DNA

Collection of:

  • blood samples
  • feces
  • biopsies (intestine / skin)
  • saliva
  • urina

Study Population
Inclusion of patients with chronic severe entheropathy and of their healthy relatives

Main Inclusion Criteria:

  • Severe chronic enteropathy
  • Patients developing their first symptoms within the first 6 years of life and, in priority within the first two years of life, or patients with a disease of later onset, in case of a familial history suggestive of inherited mutations notably in families comprising several affected members
  • OR : Be a patient's relative, even if presenting with enteropathy of later onset.

Main Exclusion Criteria:

  • Subject having participated to any therapeutical clinical study in the 30 days preceding the inclusion in this study,
