Purpose: This study aimed to profile children diagnosed with hypercalcemia of different etiologies at a single center.Method: We retrospectively reviewed 13 children diagnosed with hypercalcemia of different etiologies.Results: We describe 13 pediatric cases, aged 4 months to 12 years old (median age: 8 months), diagnosed from 2018 to 2021. Six males and seven females were included...

Context: Diagnosis of non-chromosomal type disorders of sex development (DSD) has long been challenging. There is still no research on overview of a large Chinese DSD cohort.Objective: To determine the etiologic diagnosis through unbiased large-scale panel sequencing and whole-exome sequencing (WES) within a large Chinese DSD cohort.Design: Patients were recruited according to the ...

Background: To construct the growth curves of body length and weight for Chinese patients from birth to 3 years with salt-wasting 21-hydroxylase deficiency (SW 21-OHD), changes in body mass index (BMI) will also be described, so as to explore the growth pattern of these special patients and guide the monitoring of early growth.Methods: The body length and weight data of SW 21-OHD patients aged 0-3 years who visited in 4 ...

Introduction: Obesity has been on the rise in children, adolescents and young adults during the Corona virus disesase-2019 (COVID-19) outbreak. Obesity is known as the main risk factor for a number of diseases including type 2 diabetes mellitus (T2DM) and more than 90 percent of T2DM patients are overweight or obese. Along with the rise in obesity during the COVID-19 pandemic, we investigated the impact of COVD-19 pandemic on type 2 diabetes in children and ad...

Quantitative analysis of endogenous and exogenous steroid hormones is an important step for our understanding of the causes of endocrine disorders in pediatric. In this study, we developed a method to simultaneously quantify endogenous and exogenous steroids in pediatric urine and plasma. Ultra-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to simultaneously quantify steroid hormones in children plasma and urine. Under the optimum conditions, th...

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...

Background: The Phosphoglucomutase 1 (PGM1) enzyme plays a central role in glucose homeostasis by catalyzing the inter-conversion of glucose 1-phosphate and glucose 6-phosphate. Recently, PGM1 deficiency was recognized to cause the congenital disorders of glycosylation (CDGs). PGM1 deficiency is a rare, autosomal recessive inherited disease which can cause the extreme variability of clinical symptoms multi-organ dysfunction, including ketotic hypoglycemia, dilated cardiomyopat...

Background: Noonan syndrome (NS) is generally considered an autosomal dominant, multisystemic disorder caused by dysregulation of the RAS/mitogen activated protein kinase (MAPK) pathway. The latest research confirmed the existence of a form of Noonan syndrome that is inherited in an autosomal recessive pattern and identify biallelic mutations in LZTR1. In this study, we diagnosed 55 Chinese NS Children via targeted sequencing or whole exome sequencing (TS/WES).<p ...

Purpose: Growth hormone (GH) treatment has become common practice in Turner syndrome (TS) to improve final adult height. However, there are only a few studies on the analysis of good responders to GH treatment in TS. The aim of this study is to predict the responsiveness to growth hormone therapy in Turner syndrome.Methods: Among 197 TS patients registered in LG Growth study, 92 patients were excluded because of systemic illness or hypothyroidism. The cl...

Background: Maturity-onset diabetes of the young, type 2 (MODY2), caused by mutations in the glucokinase (GCK) gene is rare in a Chinese population.Objective and hypotheses: We report three Chinese families with MODY2 and sequenced the GCK gene to find novo mutation.Method: Three unrelated Chinese families with MODY2 and pedigrees were investigated. In Family 1, the proband was a 7-year-old girl with impaired fasting glucose (IFG) ...
