To read the full abstract: J Clin Endocrinol Metab. 2020 Mar 1;105(3):dgaa037.This study aimed to assess the frequency of natriuretic peptide receptor type B gene (NPR2 ) variants in 87 children with familial short stature (FSS) and evaluate their response to GH therapy. By applying whole-exome or custom-targeted NGS panel sequencing, NPR2 variants were found in 5 children (5.7%) belonging to 4 families. These variants were cla...

4.3. A clinical trial of high dose growth hormone in a patient with a dominant negative growth hormone receptor mutation

N Merchant , L Houchin , K Boucher , A Dauber

Brief Summary: This single-patient intervention study showed the efficacy of high-dose rhGH treatment in overcoming GH resistance in a child harboring a dominant-negative GH receptor (GHR) mutation.GH insensitivity includes a broad spectrum of defects (1). Laron syndrome is the best-known GH insensitivity syndrome, characterized by recessive mutations in GHR and good response to IGF-I treatment (2). Dominant-negative variants of GHR are extremely rare an...
