Center

Rare diseases of calcium and phosphate metabolism

The Norman site of the reference center for rare diseases of calcium and phosphate metabolism , labeled since 2007 and became dual-site since 2017 (CHU of Rouen and Caen) brings together care activities (clinical, radiological and biological) and research activities.

Nationally, this center is coordinated by Professor Agnès Linglart (pediatric endocrinologist) at Bicêtre Hospital. It is made up of four clinical sites (Paris, Lyon, Rouen and Toulouse ), a dental expertise site (Paris Bretonneau) and two molecular and genetic diagnosis sites (Bicêtre-Paris Sud and Caen) . It is part of the OSCAR rare diseases sector (Bone, calcium and cartilage) .

In Normandy, the 2 centers are multi-disciplinary and treat children and adults with abnormalities in the regulation of serum calcium ( hyper or hypocalcemia, hyper or hypoparathyroidism, etc.) and/or phosphatemia (hypophosphatemic rickets , tumoral calcinosis, etc.) . They benefit from the expertise of endocrinologists, nephrologists, rheumatologists, geneticists, orthopedic surgeons, neurosurgeons, dentists, periodontists, etc.
