Ferritin is a widely used iron storage indicator. At the same time, it is also viewed as an indicator of inflammation. Chronic low-grade inflammation in obese individual, especially in the one with metabolic disorders, related to comorbidities and poor prognosis. Both hyperglycemia and iron overload can induce inflammation and result in vascular endothelial dysfunction. To study the role of ferritin in obese children and its impact on artery and liver, the present study invest...

Objective: To investigate the clinical and molecular characteristics of a girl with aldosterone synthase deficiency type II (ASDII). We also identified the consequences of a novel splice site mutation in the CYP11B2 gene.Materials and Methods: A4-month-old girl presented with vomiting, diarrhea, and failure to thrive. Her 17α-OHP, cortisol, renin, and aldosterone were all in the normal range, and the ACTH stimulatio...

Insulinoma is a rare neuroendocrine tumor, usually benign, but can be life-threatening in causing hypoglycemic accidents. It presents in individuals aged between 8 and 82 years and can occur sporadically or constitute a part of multiple endocrine neoplasia type 1 (MEN-1).The nonspecific-symptoms and small size of these tumors led to difficulties of diagnosis and localization.Here we describe the case of a 11-year-old boy, who came to our attention for a ...

Turner syndrome (TS) patients are at risk for a constellation of neurocognitive and psychosocial diseases. TS is associated with an increased risk for difficulties with visual–spatial reasoning, visual–spatial memory, attention, executive functioning, motor, and math skills. Additionally, increased rates of social difficulties, anxiety, and depression are observed.Here we report the case of a 16-years-old Caucasian girl who came to our attentio...

Objective: To determine the mutation in the SRY gene in a 46,XY complete gonadal dysgenesis patient with bilateral gonadoblastoma and coexisting dysgerminoma. Evaluate the functional consequence of mutated SRY gene in the tumor risk of 46,XY DSD.Methods and Materials: The proband was a 13-year-old girl who was admitted for examination due to undeveloped secondary sexual characteristics. She had no breas...

Increasing evidence suggests that the aetiology of disorders of sex development cannot be solely explained by genetic alterations. It is highly likely that environmental factors hitting susceptible genetic backgrounds are partly causative. Zebrafish sex is highly plastic during development, making this species an ideal model for investigation of endocrine disruption and gonadal development and function. However, the hormonal regulation of these processes in zebrafish is poorly...

Glucocorticoids regulate a wide range of biological processes including metabolism. Patients with adrenal insufficiency show impaired glucocorticoid biosynthesis either caused by adrenal defects (primary adrenal insufficiency) or by defects in the pituitary gland or hypothalamus (secondary or tertiary adrenal insufficiency). The systemic consequences of differentially disrupted steroid hormone biosynthesis remain unclear. Increasing evidence suggested steroid hormone precursor...

Objective To study a large Chinese family with Type A Insulin Resistance Syndrome (TAIRS) and the members’ clinical phenotypes. Explore their genotype-phenotype relationship between environmental factors and hereditary features. Methods 19 members of the family were investigated for their past history, dietary habits and living habits. PCR and Sanger sequencing were applied to detect mutations of the INSR gene among 6 core members from the Pedigree. Besides, fasting blood...

Objective: To identify genetic mutations of a pedigree affected by severe short stature in Chinese populations for the first time.Methods: Auxological and endocrinological profiles were measured. Targeted next-generation sequencing (NGS) analyses comprising 277 shorted stature-associated candidate genes and 19 related copy number variation (CNV) regions were used to identify gene mutations in the proband. Three web-based software programs (SIFT, PolyPhen...

Objectives: Premature ovarian insufficiency (POI) is mostly considered X chromosome abnormalities in child. Few of POI cases are associated with autosomal abnormalities. This study was to identify new genes involved POI in three girls.Methods: Three girls who came to the hospital because of no menstruation were investigated. They were 14, 15, and 14 years old. They did not find any breast tissue in their physical examination. Clinical data, sex hormones,...
