Human growth is highly dependent on the GH-IGF-I axis. GH binding to GH receptor activates janus kinase 2 (JAK2)-signal transducer and activator of transcription 5b (STAT5b) pathway which stimulates transcription of IGF1, IGFBP3, and IGFALS. Although STAT5b deficiency was established as an autosomal recessive disorder, heterozygous dominant-negative STAT5B variants were reported in patients with less severe growth deficit and milder immune dysfunction. Our aim was to develop a...

Introduction: Short Stature (SS), defined as height below -2 SD, is a common reason for referral to pediatric endocrinologists. Genetic factors determine ~80% of adult height. Lately, next-generation sequencing (NGS) has led to the discovery of an increasing number of novel monogenic causes for SS.Objective: The aim of this work was to identify the genetic etiology of SS of unknown origin (SSUO) in children.<p class=...
