Genetic Association between Interleukin IL-18-137G/C and IL-18-607 C/A polymorphisms and Type 1 Diabetes in Egyptian population
Interleukin-18 also known as interferon-gamma inducing factor, Interleukin 18 is a cytokine that plays an important role in the T helper cell 1 response, by its ability to induce IFN- c production in T cells and natural killer cells. A functional variant of IL-18 gene has been reported as associated with type 1 diabetes (T1D). In the present study were analyzed two promoter single nucleotide polymorphisms (SNPs), at -607 (rs#1946518) and -137 (rs#187238) position, in 60 patient with type 1diabetes and 60 healthy individuals, both from Egyptian population. Allele and genotype frequencies of IL18 SNPs were compared in patients and controls .The genotype CC in -137 show significance according to the patient and their control (P<0.004) while the SNP – 607 don’t showed any significance between patient and control (P=0.641), respectively. Our finding suggested an association between IL18 promoter SNP -137 and susceptibility toT1DM in Egyptian population.
