Background: Homozygous natriuretic peptide receptor-2 (NPR2) mutations cause acromesomelic dysplasia, type Maroteaux, a skeletal dysplasia with extreme disproportionate short stature and recently, heterozygous NPR2 mutations have been identified also in patients with idiopathic short stature (ISS, 2–6%). SHOX mutations are found in ~2–5% of ISS cases and ~70% of Léri-Weill dyschondrosteosis (LWD) cases, characterized by disproportionat...

Background: A total of 456 skeletal dysplasias have been classified by molecular, biochemical and/or radiological criteria, into 40 groups. Despite this, the precise, final diagnosis is often difficult due to the high phenotypic and genotypic variability.Objective: To improve the molecular and clinical diagnosis of skeletal dysplasias using a custom-designed next-generation sequencing (NGS) panel.Method: A total of 56 skeletal dysp...
