Permanent Neonatal Diabetes Mellitus Due to a G32S Heterozygous Mutation in the Insulin Gene

Xu Xiao-qin , Huang Ke , Hong Fang

Background: Permanent neonatal diabetes mellitus (PNDM) is a rare form of monogenic diabetes with onset less than 6 months of age. Together, activating mutations in KCNJ11 and ABCC8 genes, that encode the Kir6.2 andsulfonylurea receptor 1 (SUR1) subunits, respectively, account for nearly 50% of PNDM cases.Case report: We present a case reported a child diagnosed with PNDM resulting from a new mutation in the insulin (INS) gene, leading to severe hypergly...

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...

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...
