    Abstract:
    BACKGROUND AND OBJECTIVE: The polymorphism of the resistin gene (RETN/RSTN) has been associated with metabolic alterations. In this study the association between the 3'UTR +62G>A polymorphism and metabolic syndrome components was evaluated. SUBJECTS AND METHODS: The population (n=218) was distributed in 3 groups: the control group with no metabolic alterations (n=77), nSMA group with isolated metabolic alterations (n=94) and MS group with metabolic syndrome (n=47). The 3'UTR +62G>A polymorphism was analyzed by PCR-RFLP. RESULTS: Central obesity was the most frequent alteration in both nSMA (56.4%) and MS (91.5%) groups followed by low c-HDL levels in the nSMA group (42.6%) and arterial hypertension in the MS group (85%). The frequency of the +62G/A genotype was 20.2% in the population. The G/A genotype was more frequently found in the MS (38.3%) and nSMA (17%) groups than in the control group (13%). The allelic distribution between the control group (+62G=0.94, +62A=0.06) and MS group (+62G=0.81, +62A=0.19) was significantly different (P=.0001). Significant associations between the G/A genotype and high values of abdominal circumference (P=.047), basal glycemia (P=.02) and systolic arterial pressure (P=.003) were found. CONCLUSION: The findings suggest the association between the G/A genotype and high values of systolic arterial pressure, basal glycemia and abdominal circumference. This association was independent of the metabolic syndrome context.
