A Girl with Beckwith–Wiedemann Syndrome and Pseudohypoparathyroidism Type 1B, a Unique Example of Multiple Imprinting Defects

Bakker Boudewijn , Sonneveld Laura , Woltering Claire , Kant Sarina

Background: Although multiple imprinting defects have been found by genetic analysis in a subset of patients with Beckwith–Wiedemann Syndrome (BWS), very few patients have been described with both genetic and clinical signs and symptoms of multiple diseases caused by imprinting defects.Methods: Methylation analysis of the KCNQ1OT1 gene was performed by Southern blot, methylation analysis of the GNAS region was done by MLPA.<p class="abs...

Background: It is well known that endocrine comorbidities occur frequently in children with cancer, especially in those with a brain tumor. In those children, increased intracranial pressure or hydrocephalus may lead to central precocious puberty. Furthermore, chemotherapy, especially alkylating agents, increases the risk for gonadal insufficiency. In this case series we describe 3 young girls with a brain tumor, who develop premature gonadotrophic activation,...

Introduction: Childhood craniopharyngioma (cCP) has excellent survival, but quality of life may be severely hampered by hypothalamic dysfunction. We aimed to evaluate treatment and hypothalamic outcomes of a Dutch cCP cohort, and evaluate the effect of centralization of care.Methods: A retrospective cohort study was performed, including cCP patients diagnosed between 2004-2021. Treatment characteristics and hypothalamic ...

Background: The NPR2 gene plays a critical role in the human growth plate. Pathogenic NPR2 variants can result in varying degrees of short stature. The majority of subjects have no specific clinical findings and are likely classified as idiopathic short stature.Objective: To describe the phenotypic spectrum, analyze genotype-phenotype correlations and assess the response and safety of growth hormone (GH...

Introduction: Health related Quality of Life (QoL) outcome is used as an argument when continuation or stopping growth hormone (GH) treatment is considered in patients with idiopathic isolated growth hormone deficiency (IIGHD) who tested GH sufficient in mid-puberty (inclusion moment for this study).Aim: To assess potential differences in QoL between patients with IIGHD who discontinued treatment and those who continued ...
