Restriction fragment length polymorphism (RFLP) is a new and precise method for the detection of the disease on the molecular level. The genetic background of Non-insulin dependant diabetes mellitus (NIDDM) has been strongly suggested, but its occurrences are obvious for other expession factors. We first investigated insulin gene polymorphism in twenty-nine Korea NIDDM patients and 11 non-diabetic controls. We found 91 percent and 86 percent of the genotype 1/1 in diabetics and controls respectively. Also genotype 1/3 was found 9 percent and 14 percent each in both groups. Genotype 3/3 revealed 0 percent in two groups. Four acromegalics who had secondary DM showed only genotype 1/1. These findings showed that class 3 allele(2.4 kb) was a weak genetic marker of NIDDM, and had a faint correlation.
限制性片段长度多态性(RFLP)是一种在分子水平上检测疾病的新的精确方法。非胰岛素依赖型糖尿病(NIDDM)的遗传背景已得到有力提示,但其发生明显受其他表达因素影响。我们首先对29例韩国NIDDM患者和11名非糖尿病对照者的胰岛素基因多态性进行了研究。我们发现糖尿病患者和对照者中基因型1/1分别占91%和86%。此外,两组中基因型1/3均占9%和14%。基因型3/3在两组中均为0%。4例患有继发性糖尿病的肢端肥大症患者仅表现为基因型1/1。这些结果表明,3类等位基因(2.4 kb)是NIDDM的一个弱遗传标记,且相关性较弱。
