Methods The study sample consisted of two independent cohorts of Chinese children and adolescents. Anthropometric indices, lipids, blood pressure, fasting glucose, insulin and percentage of fat mass were determined. PCR with restriction fragment length polymorphism analysis was performed for genotyping the rs7566605 variant. Results In each of the two independent cohorts, no significant association was observed between rs7566605 and obesity under additive, dominant or recessive model. We also did not detect any difference in the genotype frequency between all the obese children and controls. Furthermore, we did not find evidence of an association between body composition indices and metabolic phenotypes in all children. However, the triglyceride level of CC homozygotes was significantly higher than that of GG＋GC genotypes in obese children （P=0.022）. Additionally, we observed a non-significant trend of severe obesity in a post-hoc test. Conclusion INSIG2 rs7566605 variant is not associated Chinese childhood obesity in two independent cohorts. Further study is needed to verify the effect of rs7566605 on triglyceride in obese children.展开更多

Methods: Fifty-three healthy subjects, 105 subjects with simple obesity, 63 type 2 diabetic patients without obesity, and 114 type 2 diabetic patients with obesity were studied with the technique of PCR-RFLP in codon 64 of the exon region of β 3-AR gene representing the variation Trp/Arg. Results: Compared with the subjects of Trp homozygous group, the individuals with Arg allele were more elevated in WHR,MBP,SBP,DBP,FBS,PBS,FINS,PINS,FCP,PCP and lower in ISI. Frequency of Arg allele was higher in HINS subgroup without T2DM. Conclusion: The results indicate that the Trp/Arg variation might lead to insulin resistance, obesity and T2DM.β 3-AR gene is supposed to be the candidate gene of insulin resistance, obesity and T2DM in Chinese Han population.展开更多

Herein, wereport another case that differs from previous cases in phenotype.CASE SUMMARYThe proband developed diabetes at the age of 27 years, despite having a normalbody mass index (BMI). She exhibited partial impairment of islet function, testedpositive for islet antibodies, and required high doses of insulin. Her sister alsocarried the c.4G>A (p.Ala2Thr) mutation, and their mother was stronglysuspected to carry the mutated gene. Her sister developed diabetes around 40years of age and required high doses of insulin, while the mother was diagnosedin her 20s and was managed with oral hypoglycemic agents;neither of them wereobese.CONCLUSION p.Ala2Thr mutation carriers often experience relatively later onset and normalBMI. Treatment regimens vary between individuals.展开更多
