Patients With RETT Syndrome

It was proposed to the French Association of Rett Syndrome (AFSR) to perform an extensive biological assessment in a series of 100 girls with Rett's syndrome and carriers of a mutation in the MECP2 gene in order to confirm or confirm to reverse the abnormalities identified previously and possibly, to highlight new biomarkers of the pathology. The analysis will focus on classical hematological criteria, iron markers, endocrine assays, lipid quantification and markers of inflammation. At the end of the project, each family will receive the complete biological assessment carried out on their daughter which will represent a direct benefit of the implication in this clinical research project.
