Electronic address:

Background: The literature on laminopathy with ventricular phenotype is extensive. However, the pathogenicity of LMNA variations in atrial lesions still lacks research.

Objective: The purpose of this study was to characterize the atrial phenotypes and possible mechanisms in a large Chinese family with heart-hand syndrome carrying a LMNA missense variant in rod 2B domain (c.

Clinical Characteristics of Short-Stature Patients With an NPR2 Mutation and the Therapeutic Response to rhGH.

J Clin Endocrinol Metab

January 2021

Key Laboratory of Endocrinology of National Health Commission, State Key Laboratory of Complex Severe and Rare Diseases, Department of Endocrinology, Peking Union Medical College Hospital, Chinese Academy of Medical Science and Peking Union Medical College, Beijing 100730, China.

Context: The natriuretic peptide receptor 2 gene (NPR2) is a causative gene of idiopathic short stature (ISS) with an incidence rate of 2% to 6%. The clinical characteristics of patients with NPR2 heterozygous mutations are atypical, and data on the efficacy of recombinant human growth hormone (rhGH) treatment in patients with NPR2 mutations are limited.

Objectives: This work reports 6 cases with NPR2 mutation and explores the characteristics of patients with an NPR2 mutation and their therapeutic response to rhGH.

Holt-Oram syndrome (HOS) is a rare autosomal dominant disorder characterized by upper limb defects and congenital heart defects (CHD), which are often simple septal and conduction defects, less frequently complex CHDs. We report on a 9 year-old boy with clinical and radiologic features of HOS consisting of bilateral asymmetric hypoplastic thumbs, generalized brachydactyly, limited supination due to radioulnar synostosis, and sloping shoulders, and intermediate atrioventricular canal defect (AVCD) with aortic coarctation. A de novo, previously described mutation, (Arg279ter) was identified in the TBX5 gene.
