Background: Mutations in SHOX or its regulatory regions have been detected in ~70% of Léri-Weill dyschondrosteosis (LWD) and ~2.5% of idiopathic short stature (ISS) cases, suggesting the implication of other genes or loci. Recent studies have identified NPR2 defects in ISS patients.Objective and hypotheses: To investigate if NPR2 mutations can account for a proportion of the cases referred for LWD and ISS in whom no SHOX/PAR1 mutation was detected.<...

Background: Disproportional short stature (DSS) is the most frequent clinical presentation of skeletal dysplasias, which are a heterogeneous group of more than 450 disorders of bone. Skeletal survey is important to establish the diagnosis and to guide the genetic test, but has several limitations, especially in mild and atypical cases.Objective and hypotheses: To identify the genetic aetiology of DSS by exome sequencing.Method: Who...

Introduction: The majority of children with short stature are classified as ISS by the absence of findings that could elucidate the cause of their growth impairment. Several monogenic defects have already been identified in children with ISS, but the candidate gene approach is not feasible when there are no specific findings to guide a specific genetic test.Objective: To evaluate the diagnostic yield of a targeted gene p...

Objective: Most children with short stature remain without an etiologic diagnosis after extensive clinical and laboratory evaluation and are classified as idiopathic short stature (ISS). This study aimed to determine the diagnostic yield of a multigene gene analysis in children classified as ISS.Design and Methods: We selected 102 children with ISS and performed the genetic analysis as part of the initial investigation. ...
