Abstract

Background

Type 2 diabetes mellitus (T2DM) is the most common type of diabetes. It is caused by inefficient insulin use, as well as the progressive loss of pancreatic β cells function. T2DM is the most common type of diabetes in the world. It is the major cause of death in adults and children, mainly of heart disease. The non-synonymous polymorphism rs1990760 is located in the HNF-3b binding site within exon 15 of the IFIH1 coding region. At codon 946, it encodes a change from alanine to threonine (Ala 946 Thr).

Methods

On 100 patients and 100 controls, a case-control study was conducted. After extraction of genomic DNA, the SNP rs 1,990,760 analysis was performed using Taq-man real time PCR (RT-PCR). Fasting blood sugar, insulin level, HOMA-IR and lipid profile were determined. Anthropometric parameters such as height, weight and BMI were calculated. T2DM risk was determined as an odds ratio.

Results

TT, CT genotype carriers were less likely to develop T2DM [OR = 0.38, CI 95% = 0.17–0.82, P = 0.01] and [OR = 0.40, CI 95% = 0.16–5.99, P = 0.04] respectively.

High density lipoprotein (HDL) is shown significant differences in codominant model among genotypes in the patient's group.

Conclusion

Interferon-induced helicase (IFIH1) gene polymorphism rs1990760 is involved in reduced risk of T2DM. In addition this SNP may play a role in the development of cardiovascular diseases by affecting HDL levels.

干扰素诱导解旋酶(IFIH1)基因多态性rs1990760与伊拉克人群2型糖尿病的关系
2型糖尿病(T2DM)是最常见的糖尿病类型。它是由胰岛素使用效率低下以及胰腺β细胞功能的逐渐丧失引起的。2型糖尿病是世界上最常见的糖尿病类型。它是成人和儿童死亡的主要原因,主要是心脏病。非同义多态性rs1990760位于IFIH1编码区外显子15内的HNF-3b结合位点。在密码子946处,它编码从丙氨酸到苏氨酸的变化(Ala 946 Thr)。方法对100例患者和100例对照者进行病例-对照研究。提取基因组DNA后,采用Taq-man real time PCR (RT-PCR)对SNP rs 1,990,760进行分析。测定空腹血糖、胰岛素水平、HOMA-IR和血脂。计算身高、体重、BMI等人体测量参数。T2DM风险以比值比确定。结果stt、CT基因型携带者发生T2DM的可能性较低[OR = 0.38, CI 95% = 0.17 ~ 0.82, P = 0.01]和[OR = 0.40, CI 95% = 0.16 ~ 5.99, P = 0.04]。高密度脂蛋白(HDL)在患者组基因型共显性模型中表现出显著差异。结论干扰素诱导解旋酶(IFIH1)基因多态性rs1990760与T2DM发病风险的降低有关。此外,这种SNP可能通过影响HDL水平在心血管疾病的发展中发挥作用。
