Background: Achondroplasia (ACH) is a rare genetic condition caused by a gain-of-function variant in the fibroblast growth factor receptor 3 (FGFR3) gene. It results in severe disproportionate short stature and medical complications requiring multidisciplinary care. Vosoritide, a C-type natriuretic peptide analogue, is currently the only approved targeted treatment for children with ACH from birth to epiphyseal closure. Understanding real-world ACH management ...

Objective: To explore the diagnostic value of morning urinary gonadotropins for assessing central precocious puberty (CPP) in girls with varying BMI and the potential use of first morning voided urinary luteinizing hormone (FMV ULH) in monitoring CPP treatment.Methods: A total of 335 precocious puberty girls were selected. Data of serum luteinizing hormone (LH), follicle stimulating hormone (FSH), gonadotropin-releasing ...

Background: Steroidogenic factor-1 (SF1) is a nuclear receptor transcription factor that plays a crucial role in regulating the adrenal, gonadal, splenic development, steroidogenesis and reproduction.Objective: To describe a Chinese 46,XY female with sex reversal, primary adrenal insufficiency and congenital splenic dysplasia harboring a novel de novo heterozygous deletion in NR5A1 gene.<p class="ab...

Results: Total of 47 obese patients (20 females, 39 pubertals, mean age of 14.3 years).±3.2 years) were included in the study. Severe obesity present in 85% of patients, early-onset obesity in 51%, consanguinity among parents in 17%, and at least one parent with obesity in 63.8% were present. 55.3% of the patients had a family history of diabetes, 63% had acanthosis nigricans and 77% had striae. Anthropometric and laboratory ch...

Background: What initiates pubertal process in humans and other mammals has remained elusive.Objective and hypotheses: We hypothesize that gene(s), whose products trigger the GnRH pulse generator to restart ticking at the usual time of puberty, can be identified via autozygosity mapping together with whole exome sequencing in patients with idiopathic hypogonadotrophic hypogonadism (IHH).Method: We studied a cohort IHH cases. Functi...

Objective: To study the clinical features and gene mutations of neonatal diabetes mellitus (NDM) in Chinese patients.Methods: Patients with clinically diagnosed NDM were subjected to genetic screening by targeted gene capture of the genes associated with glucose metabolism, and followed up.Results: Of the 23 cases of NDM studied, 16 (69.6%) were permanent neonatal diabetes mellitus (PNDM), 6 (26.1%) were transient neonatal diabetes...

Background: X-linked adrenal hypoplasia congenita (AHC) is a rare disorder characterized by primary adrenal insufficiency (PAI) and hypogonadotropic hypogonadism (HH), with limited clinical and genetic characterization.Methods: The clinical, biochemical, genetic, therapeutic, and follow-up data of 42 patients diagnosed with X-linked AHC were retrospectively analysed.Results: Hyperp...

Introduction: Regenerating endogenous pancreatic β-cells is a potentially curative yet currently elusive strategy for diabetes therapy. Mimicking the microenvironment of the developing pancreas and leveraging vascular signals, critical to pancreatic endocrinogenesis, may promote β-cell regeneration. We aimed to investigate whether recovery from experimental hypovascularization of the endocrine pancreas could trigger mouse ß-cell proliferation.<...

Introduction: The transferrin receptor (TFRC) is abundant on the surface of ß-cells compared to neighboring α- and ∂-cells, suggesting an important role of iron in ß-cell biology. The precise impact of iron on ß-cell development, function, and survival remains elusive. Here, we investigated the role of iron metabolism in mouse and human ß-cells through chemical and genetic modulation of iron supply.<str...

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 ...
