Objective: To explore the clinical characteristics of diagnosis and treatment in patients with congenital tufting enteropathy.Method: A rare case of congenital tufting enteropathy was diagnosed at West China Second University Hospital, Sichuan University in July 2016, the clinical data of congenital tufting enteropathy was analyzed retrospectively, and the related literature were reviewed. Original papers on congenital tufting enteropathy published until...

Background: The differential diagnosis of partial precocious puberty (PPP) and central precocious puberty (CPP) is vital to the prompt intervention and administration, but their specific biomarkers are still unavailable. The potential harmful effects of environmental factors on children's growth and development attract great concern and require urgent investigation.Objective: The metabolic differences and connection...

Background: Fibroblast growth factor receptor 3 (FGFR3) is a negative regulator of skeletal development. Gain-of-function point mutations in FGFR3 are responsible for hypochondroplasia (HCH), one of the most common forms of dwarfism in humans. Autophagy is an evolutionarily conserved catabolic process, which is indispensable for cell homeostasis maintenance and stress responses. Dysregulation at the level of autophagic activity consequently disturbs the chondr...

Objectives: Congenital hypothyroidism (CH) is the most common neonatal endocrine disorder in infancy. The aim of this study was to screen for reported gene mutations among CH patients in our hospital and to illustrate a genetic mutation spectrum of CH in China.Methods: We designed a gene panel consisting of more than 20 relevant genes including TSHR and DUOX2. Blood samples were collected from 60 CH patients and their parents in Children’s Hospital ...

Keywords: growth hormone, small for gestational age, genetic defects; Silver-Russell syndrome; growth hormone deficiencyObjectives: To evaluate the influencing factors of GH treatment in Chinese short stature children born SGA.Methods: This was a single-center, retrospective, cross-sectional survey in China. Of 101 patients were identified born SGA and 66 short stature children bor...

Mandibulofacial dysostosis with microcephaly (MFDM) is characteristic of multiple skeletal anomalies comprising craniofacial anomalies/dysplasia, microcephaly, dysplastic ears, choanal atresia and short stature. Loss of function mutations of EFTUD2 were previously reported in MFDM, however, the mechanism underlying EFTUD2-associated skeletal dysplasia remains unclear. Here, we identified a novel frameshift mutation of EFTUD2 in a MFDM Chinese patient...

Keywords: Sleep-Related Breathing Disorders, recombinant human Growth Hormone treatment, Prader–Willi syndrome, Toddlers.Background: Recombinant human growth hormone (rhGH) therapy is beneficial for children with Prader–Willi syndrome (PWS) in improving short stature and metabolism, but the effect of early rhGH treatment on respiratory and sleep parameters for the PWS children under three years old remains el...

Objective: 21-hydroxylase deficiency (21-OHD) is the most common cause of congenital adrenal hyperplasia due to CYP21A2 gene mutation. The aim of study is to expand CYP21A2 mutational spectrum in the Chinese population and to provide novel genetic information in terms of ethnic diversity.Methods: 95 Chinese suspected 21-OHD patients with phenotypes varying from salt-wasting (SW) to nonclassic symptoms w...

Background: Androgen insensitivity syndrome (AIS) is a common 46XY disorders of sex development (DSD), which is mainly caused by mutations in the androgen receptor (AR) gene. The clinical manifestations vary among patients, depending on residual androgen receptor activity.Methods: Five patients with different degrees of masculinization of external genitalia were selected as the research objects. As well as the detailed m...

Cornelia de Lange syndrome (CdLS) is a multisystem organ developmental disorder characterized by growth and cognitive deficits and premature aging, caused by mutations in genes coding for the cohesin complex. CdLS cells presented with gene expression dysregulation, genomic instability, decreased energy production and oxidative stress. Variants in the cohesin loading factor Nipped-B-like (NIPBL) gene can be identified in approximately 70% of cases and the ...
