NCT06213103

Brief Summary

The study aims at characterizing the immune dysfunctions in patients with mitochondrial diseases. This has prognostic and diagnostic interest as well as potential for the discovery of new therapeutic strategies to alleviate disease burden.

Outcome Measures

Primary Outcomes (2)

  • Immunological parameters

    Distribution of several quantitative immunological parameters at inclusion. The following parameters will be considered : Immunoglobulins in g/l (IgG subclasses, IgA, IgM)

  • Person affiliated with or receiving a social security plan;
  • Patient with molecularly proven primary mitochondrial disease
  • Free, informed, written consent signed by parental authority holders for minor patients and the investigator prior to any examination required by the research and oral and/or written assent by the participant (depending on age).
  • Free, informed consent signed by the patient's representative for adult patients under guardianship and the investigator prior to any examination required by the research.
  • Free, informed consent signed by the patient of legal age and the investigator prior to any examination required by the research
  • Person who has been informed of the purpose of the study and person matched in age (+/- 5 years) and sex to a patient with primary mitochondrial disease at the time of sampling
