Background: The calcium-sensing receptor (CASR) is Class C G protein-coupled receptor (GPCR). CASR is responsible of calcium set point and it is expressed in several tissues: parathyroid, C-Cells, and kidney cells. CASR activating mutations are responsible of autosomal dominant hypocalcaemia 1 (ADH1; OMIM # 601198) and more than 100 different mutations have been described. ADH1 is not always associated with hypercalciuria. Nagase et al. described for ...

Background: Prader–Willi syndrome (PWS) is a rare genetic disorder caused by a loss of function of specific genes on chromosome 15. It is characterized by infantile lethargy and hypotonia causing poor feeding and failure to thrive, childhood obesity, short stature, and hypogonadism, that causes incomplete, delayed, and sometimes disordered pubertal development.1 Precocious puberty is very rare in PWS. We report a girl with PWS and idiopathic p...
