Case: A 7-year-old female revealed short bowed femurs and humeri with old fractures and bowed tibias and fibulas. Her height was 97cm and weight was 11kg. Her younger sister had the same phenotype as same as her mother. The Trio WES test showed that they all inherited from their mother's COL1A2 gene mutation (c.928G>A; p.G328S) and diagnosed Osteogenesis Imperfecta, type IV. Unfortunately, the 7-year-old girl also presents coarse face, short neck, limi...

Purpose: This study aims to investigate the effect of GnRHa on GH-IGF-1 axis and to evaluate if −202 A/C IGFBP-3 promoter polymorphism affects the growth velocity during treatment on girls with central precocious puberty (CPP).Methods: Data was collected from 97 girls, diagnosed under 9 year of age and treated by GnRHa for at least 1 year in Kangdong Sacred Heart Hospital between 2014–2015. Their body height, weight, Δ Height standard dev...

Background: Turner syndrome (TS) is due to complete or partial deletion of an X chromosome. The most common clinical features encountered in TS patients were short stature and primary amenorrhea.Objective and hypotheses: The purpose of this study was to investigate the causes of short stature in TS.Method: 86 patients with TS were diagnosed by karyotypes from 2004 to 2013, the karyotypes distribution were as follows: 64 patients wi...

Background: It is now widely accepted that chemical pollutants in the environment can interfere with the endocrine system. The impact of endocrine disrupting chemicals on puberty disorders is concerned. bisphenol-A (BPA) has been measured in fetal plasma. There are different toxic effects with different doses of BPA.Objective and hypotheses: To observe vaginal opening day (VOD) hypothalamic kiss-1 gene and ovarian estrogen receptors (ER) gene expression ...

Background: Studies about the genetics of congenital adrenal hyperplasia caused by 21-hydroxylase deficiency congenital adrenal hyperplasia (CAH) in Chinese children are less.Objective and hypotheses: Study the genotypes of Chinese probands with salt-wasting form of congenital adrenal hyperplasia caused by 21-hydroxylase deficiency (CAH) and performed pedigree-based linkage analysis.Method: We have performed genetic-testing (Method...

Background: Nearly half of SRS epigenetic etiology is unknown. Effect of GH in SRS is not exact.Objective: To determine novel gene or imprinted gene associated with pathogenicity of Silver–Russell syndrome (SRS) through detection genome-wide methylation differences. To observe GH efficacy in SRS and the relationship between GH and epigenetic changes.Method: To detect genome-wide methylation site through the Illumina 450K methy...

Objective: To recognize Schimke immune-osseous dysplasia from a case of spinal epiphyseal dysplasia.Method: Summarize the characteristics of one case of Schimke immune-ossesous dysplasia, and increase awareness of this disease.Result: The patient, male, with non-consanguineous parents, was born on May 8, 2012. He was hospitalized in our hospital in January 2020 due to his short stature for more tha...

Purpose: Identify CYP21A2 gene variants in pediatric patients with congenital adrenal hyperplasia due to 21-hydroxylase deficiency from Henan, China, and to analyze genotype-phenotype correlations. We also analyze the relationship between the clinically effective dosage of hydrocortisone and CYP21A2 genotype.Materials/Methods:A total of 214 21-OHD children were recruited in Henan children's hospital from 2008 to 202...

Objective: The onset of obesity complicated with metabolic syndrome in children and adolescents is hidden, the mechanism is unknown, and early warning indicators are lacking clinically. This study conducted multi-omics research on children and adolescents with simple obesity and obesity complicated with metabolic syndrome to provide early clinical diagnosis and drug treatment targets for its occurrence and development mechanism.M...

Objectives: To describe safety and effectiveness of high (≥90-180 µg/kg) and low (<90-30 µg/kg) dose leuprorelin in treating central precocious puberty (CPP).Methods: In this observational, retrospective study, effectiveness was evaluated based on regression or no progression of Tanner staging as the primary outcomes. LH, FSH, estradiol or testosterone suppression, and decrease in bone age to chronolo...
