OBJECTIVE
Zinc transporter 8 (ZnT8) is a multi-transmembrane protein situated in the insulin secretory granule of the islets of β-cells and is identified as a novel auto-antigen in type 1 diabetes (T1D). The gene coding for ZnT8, solute carrier family 30 member 8 () is located on chromosome 8q24.11. This study aimed to identify the association of rs13266634 C/T gene polymorphism with T1D in a sample of T1D children in Tamil Nadu, India.
METHODS
The family based study was conducted in 121 T1D patients and 214 of their family members as controls. The gene rs13266634 C/T polymorphism was evaluated by polymerase chain reaction-restriction fragment length polymorphism.
RESULTS
No significant differences were observed in either allele (odds ratio: 0.92; confidence interval: 0.33-2.58; p=0.88) and genotype (CC: p=0.74; CT: p=0.82; TT: p=0.80) frequencies of rs13266634 C/T between T1D patients and controls. Transmission disequilibrium test has identified over-transmission of mutant T allele from parents to affected children (T: U=9:7) without statistical significance. Metaanalysis on the overall effects of rs13266634 C allele frequency was not different (p=0.10 and P=0.99) in T1D patients as compared to the controls.
CONCLUSION
The present study along with the meta-analysis does not show any substantial association of the rs13266634 C/T polymorphism with T1D development in this population.
目的
锌转运体8（ZnT8）是一种位于β细胞胰岛胰岛素分泌颗粒中的多跨膜蛋白，被确定为1型糖尿病（T1D）中的一种新型自身抗原。编码ZnT8的基因，溶质载体家族30成员8（）位于8号染色体q24.11上。本研究旨在确定印度泰米尔纳德邦T1D儿童样本中rs13266634 C/T基因多态性与T1D的关联。
方法
基于家系的研究纳入了121例T1D患者及其214名家庭成员作为对照。通过聚合酶链反应-限制性片段长度多态性评估基因rs13266634 C/T多态性。
结果
在T1D患者和对照之间，rs13266634 C/T的等位基因（优势比：0.92；置信区间：0.33 - 2.58；p = 0.88）和基因型（CC：p = 0.74；CT：p = 0.82；TT：p = 0.80）频率均未观察到显著差异。传递不平衡检验确定突变T等位基因从父母向患病子女的过度传递（T：U = 9：7），但无统计学意义。与对照相比，T1D患者中rs13266634 C等位基因频率的总体效应的荟萃分析无差异（p = 0.10和P = 0.99）。
结论
本研究以及荟萃分析均未显示该人群中rs13266634 C/T多态性与T1D发生有任何实质性关联。
