Introduction: Phosphoglucomutase 1 catalyzes the interconversion of glucose-6-phosphate and glucose-1-phosphate. Phosphoglucomutase 1 deficiency (PGM1-CDG), previously termed glycogenosis type XIV (OMIM 612934), is a rare variant of the congenital disorders of glycolysation (CDG), resulting in abnormal attachment and processing of protein linked N-glycans. We present a girl with PGM1-CDG and delayed pubertal development and review the endocrine findings of the few pat...

Introduction: Gain-of-function mutations in the STAT-3-Gene are associated with multisystemic autoimmune disease. The spectrum of disorders described in this context is highly variable and includes lymphoproliferative disease and (poly-) autoimmune endocrinopathies.Case History: A three-year-old boy was admitted with acute liver failure of unknown cause, necessitating a liver transplant. His medical history included cong...

Background: P450 oxidoreductase (POR) mutations can present with disordered sexual development (46,XX virilisation as well as 46,XY under-masculinisation), perturbed steroidogenesis and mild to severe skeletal malformations. As POR is an obligate electron donating cofactor to many P450s, and as this interaction may vary from partner to partner, the phenotypic spectrum of PORD is extremely broad. Therefore, to characterize novel POR mutations, specific testing is required.<...
