Abstract

Type 2 diabetes mellitus (T2DM) is the most prevailing worldwide health challenge of the 21st century and the 5th leading cause of death worldwide. About 90% of diabetic patients are diagnosed as having T2DM. LPAR1 gene codes LPA protein that is involved in the regulation of many biological processes. In this study, we have investigated the association of single nucleotide polymorphism (SNP) of LPAR1 gene variants rs494605 and rs558347 with T2DM in our local population. This association was analyzed by amplification of the target gene through Tetra ARMS PCR. The study involved 200 participants with equal ration of cases and controls. Both genetic variants of LPAR1 rs494605 and rs558347 have allelic origin T/C. The allelic frequency of LPAR1 was calculated through the Hardy Weinberg Equilibrium. re found that in LPAR1 rs494605 mutant allele, C was 47% in cases compared to controls (39%) and in LPAR1 rs558347, heterozygosity allele (TC) was 46% compared to mutant allele C (13%), while wild T allele was 17% in cases. Many demographic and lifestyle risk factors were significantly associated with LPAR1 gene variants. The heterogeneity of genetic variants with T2DM also showed a strong correlation with obesity, hormonal imbalance, and depression with p-value of 0.001, and 95% confidence interval. Smoking and alcohol consumption are major risk factors of T2DM. Variations in LPAR1 can be used as a biomarker and diagnostic tool for T2DM.
