Introduction: Patients carrying homozygous IGF1 loss-of-function mutations are extremely rare and show severe pre- and postnatal growth failure, microcephaly, developmental delay, retrognathia and sensorineural deafness. Heterozygous variants in IGF1 appear to be more common in short stature, but only few cases have been reported in detail. Therefore, clinical features and growth response to recombinant human growth hormone (rhGH) therapy are...

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: Among children with short stature, some show persistent IGF-I levels <-2.0 SDS despite a normal growth hormone (GH) response in a stimulation test. This may be caused by conditions that could benefit from recombinant human GH (rhGH) therapy (e.g. GH neurosecretory dysfunction, bioinactive GH, partial GH insensitivity). Therefore, the IGF-I generation test (IGFIGT) was implemented in 2006 using a national, standardized protocol. Children with a...

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 ...
