Background: Wolfram syndrome features diabetes insipidus, diabetes mellitus, optic nerve atrophy, and deafness (DIDMOAD). Especially the neurological degeneration usually leads to a very poor prognosis. We present two cases of Wolfram syndrome, an autosomal dominant and an autosomal recessive type, caused by heterozygous mutations in the WFS1 gene.Case report: Case 1: a 13-year-old girl with a history of progressive sensorineuronal hearing loss ...

Pseudohypoparathyroidism: Clinical Heterogeneity Illustrated by Three Different Cases

Lemay Annelies , den Brinker Marieke , Dotremont Hilde , Ceulemans Berten , France Annick

Background: Pseudohypoparathyroidism represents a group of clinical and molecular heterogeneous disorders, characterized by functional hypoparathyroidism, caused by end-organ resistance to the action of PTH. Pseudohypoparathyroidism manifests as hypocalcemia, hyperphosphatemia and elevated plasma levels of PTH. A combination of features, also known as Albright osteodystrophy including disproportionate short stature, obesity, dysmorphia, may co-exist.Case...

Background/ Aim: Over the past 6 years, the IGF1/ IGFBP3 generation test (IGFGT) has been used in Belgium in a standardized form to identify children with severe primary IGF1 deficiency (SPIGFD). In this study, the discordance of the IGF1 and IGFBP3 responses during an IGFGT and the prevalence of SPIGFD were analyzed in a cohort of children with short stature (height SDS < - 2) and presenting with low (below lower reference limit) serum IGF1 level and norma...

Background/Aims: Cryptorchidism or undescended testis is a prevalent congenital urogenital condition affecting male newborns with an incidence rate ranging from 1.0 to 4.6%. Mouse models have implicated INSL3 and its receptor RXFP2 (formerly known as GREAT or LGR8) in the development of the condition. RXFP2 acts as a G protein-coupled receptor that triggers the generation of cAMP by binding INSL3. But despite the established role in testicular descent, so far ...
