Introduction: Prader Willi Syndrome (PWS) is a genetic disorder caused by the lack of expression of paternally inherited genes in chromosome 15q11-q13 region. Central adrenal insufficiency (CAI) has been described but its prevalence is unknown.Aim: to assess central adrenal function in a group of prepuberal PWS patients suspected of CAI.Methods: PWS patients with confirmed molecula...

Introduction: ABCD syndrome is characterized by hypercalcemia, hypercalciuria, nephrocalcinosis, and renal impairment, generally under 4 years old. This is a rare cause of pediatric hypercalcemia with only 7 cases published, but it is believed to be underdiagnosed. The suspected mechanism would be associated with overexpression of transient receptor potential channels (TRP) that modulate intestinal absorption of calcium, since TRP-M2 is encoded on chromosome 2...

Introduction: Congenital disorders of glycosylation (CDG) are metabolic conditions resulting from defects in the glycosylation pathway. In addition to the primary neurological symptoms, other possible clinical findings may include distinctive coagulation abnormalities, as well as hepatic, gastrointestinal and, less frequently, hormonal disorders. The ALG1 gene defect is the third most prevalent CDG and compromises β-1,4 mannosyltransferase activity, which...
