ABSTRACT
Genetic differences between Asians and Caucasians may be involved in the rapid increase in lifestyle-related diseases in the Asia-Pacific region that has coincided with Westernisation of diets in the region. In the present study, we assessed correlation between 10 single nucleotide polymorphisms (SNPs) and chronic disease risk factors in age-matched and population-based groups in four Asian-Pacific locations: Okinawa, Palau and Thailand (two areas). The following allelic SNP profiles significantly differed (p<0.01) among the four populations, in both men and women: uncoupling protein 2 (UCP2), uncoupling protein 3 promoter (UCP3p), leptin receptor (LEPR) exon 6, and angiotensinogen (AGTa-20c). Multiple regression analyses showed significant associations between SNPs and clinical data. For men, these associations were between beta3 adrenergic receptor (beta3AR) and diastolic blood pressure (DBP) (p<0.01), UCP3p and total cholesterol (p<0.01), UCP2 and age (p<0.05), and AGTa-20c and age (p<0.01). For women, these associations were between LEPR exon 14 and body mass index (BMI) (p<0.05), UCP2 and systolic blood pressure (p<0.05), UCP3p and DBP (p<0.05), UCP2 and DBP (p<0.01), apolipoprotein E (ApoE)nd total cholesterol (p<0.01), beta3AR and triglyceride (p<0.05), AGTa-20c and triglyceride (p<0.05), and UCP2 and age (p<0.05). These results illustrate the interrelationships among SNPs and risk factors in the Asia-Pacific including China and Japan.
