Partial Thyroxine Binding Globulin Deficiency in Test Tube Babies: Cases Report and Literatures Review

Yanlan Fang , Chunlin Wang , Li Liang

Background: Partial thyroxine-binding globulin deficiency (TBG-PD) is an endocrine defect with a prevalence of 1:4 000 in newborns. Due to the presence of a single TBG gene on the X chromosome.Objective and hypotheses: To investigate the clinical characteristics of twins with thyroxine binding globulin deficiency and to find SERPINA7 gene mutations.Method: Data related to clinical characteristics, serum biochemistry, gene mutations...

Serum Bisphenol a Concentration and Premature Thelarche in Female Infants Aged 4-Month to 2-Year-Old

Yanlan Fang , Lianhui Chen , Li Liang

Background: Bisphenol A (BPA) is one of high production-volume chemicals and used extensively in consumer products, including food containers and epoxy food-can coatings. The primary source of BPA exposure in adults is via food and beverages, while among infants breast milk and polycarbonate feeding bottles are the predominant source of BPA exposure.Objectives and hypotheses: To estimate the association between serum BPA A and premature thelarche in fema...

Level of Non-HDL Cholesterol and its Related Factors in Chinese Han Students

Yanlan Fang , Li Liang , Junfen Fu

Background: Cardiovascular disease is one of the most prominent causes of mortality world widely. A key related factor of atherosclerotic cardiovascular disease is the presence of dyslipidemia. Together with elevated blood pressure, obesity, and diabetes mellitus, dyslipidemia is a component of metabolic syndrome and associated with an increasing incidence of coronary heart disease.Objective and hypotheses: The aim of this study was to investigate the co...

Insulin Resistance Leads to Mitochondrial Dysfunction in Hepatocyte

Chen Hong , Fang Yanlan , Liang Li , Wang Chunlin

Background: Insulin resistance in obesity and type 2 diabetes is associated with abnormalities in mitochondrial oxidative phosphorylation in skeletal muscle. Whether mitochondrial function changes in hepatocytes with hereditary insulin resistance is not clear. Type A Insulin Resistance Syndrome (TAIRS) is a rare disorder characterized by severe insulin resistance, a condition in which the body's tissues and organs do not respond properly to the hormone ins...

Complex Single Nucleotide Polymorphisms in SEPINA 7 Lead to TBG Deficiency

yanlan Fang , Hong Chen , Li Liang , Chunlin Wang

Objective: Thyroxine binding globulin (TBG) is the most important thyroid hormone transporter in humans and is encoded by the SERPINA7 gene located on chromosome Xq22.2. By analyzing the genes of TBG-deficient patients, we aim to find a new molecular basis for the possible etiology of the disease.Design and Methods: 10 groups of subjects were enrolled in the pediatric department of the First Affiliated Hospital of Zhejia...

A Novel Compound Heterozygous Mutation in the CYP11B2 Gene, Including an Intron 7 Splice Site, is Responsible for Aldosterone Synthase Deficiency Type II

Zhu Jianfang , Chen Hong , Wang Chunlin , Fang Yanlan , Kong Yuanmei , Liang Li

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...

Indentification of a de Novo Mutation in the SRY Gene in a 46,XY Complete Gonadal Dysgenesis Patient with Gonadal Neoplasia and Review of Tumor Risk in 46,XY DSD Patients

He Minfei , Chen Hong , Zhu Yilin , Fang Yanlan , Zhu Jianfang , Liang Li , Wang Chunling

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...

Family Investigation and Clinical Phenotype Analysis of Type A Insulin Resistance Syndrome

Chen Yonghua , Chen Hong , Fang Yanlan , Wang Chunlin , Zhu Jianfang , Liang Li

Objective To study a large Chinese family with Type A Insulin Resistance Syndrome (TAIRS) and the membersÂ’ 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...

Premature Ovarian Insufficiency in Girls Caused by Autosomal Microdeletions: 3 Case Reports

Yuan Ke , He Minfei , Fang Yanlan , Zhu Jianfang , Liang Li , Wang Chunlin

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,...
