Sirtuin 1 (SIRT1) is a longevity gene that protects cells against oxidative and genotoxic stress. This study aimed to investigate the associations of SIRT1 gene single nucleotide polymorphisms (SNPs), rs7895833, rs7069102, and rs2273773, with various laboratory data in 1279 Japanese health checkup examinees. The genotyping was performed using a polymerase chain reaction (PCR) with confronting 2-pair primers (CTPP) assay. ⋯ The T allele of rs2273773 in men carried a high risk for hyperglycemia. In conclusion, these SIRT1 gene polymorphisms are associated with high body fat and blood pressure in Japanese, especially in men. The allele frequencies of rs7895833 and rs7069102, which are different from Caucasians, might explain why Japanese show less marked obesity compared with Caucasians.
