Clinical trials: Steroidogenesis
Friedreich's Ataxia, Steroidogenesis
FRIEDREICH ATAXIA- STEROIDOGENESIS
Friedreich's ataxia (FA) is a rare autosomal recessive disorder caused by GAA repeat expansion in the FXN gene, leading to impaired iron-sulfur (Fe-S) cluster biosynthesis and mitochondrial dysfunction.

Gitelman Syndrome, Potassium Depletion
Monocentric STUDY, Randomised Double Blinded (Healthy Subjects, or Transversal (Patients With Gitelman Syndrome)
Progesterone is needed to permit adaptation of the kidney to limit potassium loss in the urines. The investigators wonder whether progesterone or other adrenal hormon play the same role.

Disorders of Sex Development, Congenital Adrenal Hyperplasia
Gene Polymorphisms Influencing Steroid Synthesis and Action
The extend of steroid biosynthesis and action is mainly dependent on underlying genetic polymorphisms and gene mutations. These sequence variations in multiple genes involved in steroid biosynthesis and action cause different…
