The tubulopathy network of the Georges Pompidou hospital (HEGP) centralizes the most important national database on inherited tubulopathies with international recognition. Through constant interactions between the genetics department (R Poussou Vargas), the center of clinical investigation (A Blanchard), the department of clinical physiology (S Baron) and the scientific PIs based at the CRC, we currently investigate the phenotype/genotype correlations of several tubulopathies (Dent, Bartter, Gitelman, HELIX) and plan to launch clinical and therapeutic trials.
