Different constitutions have specific metabolic features and different susceptibility to certain diseases. However, whether a genetic basis accounts for such constitution classification is yet to be determined. Here we performed a genetic study to assess the association between genetic variations of metabolic genes including PPARD, PPARG and APM1 and the constitutions. A total of 233 individuals of the Han population in China were classified into four groups, Normality, Yang-deficiency, Yin-deficiency and Phlegm-wetness with whom 23 single nucleotide polymorphisms （SNPs） in the three genes were genotyped using polymerase chain reaction-restriction fragment length polymorphism （PCR-RFLP） method. Biased distribution of PPARD rs2267669 and rs2076167, APM1 rs7627128 and rs1063539 in Yang-deficiency, PPARG Prol2Ala in Yin-deficiency and PPARD rs2076167, APMI rs266729 and rs7627128 in Phlegm-wetness were observed. The frequencies of Haplotypel3 （Hapl3） of PPARG in Yin-deficiency, Hap25 of APM1 in Yang-deficiency and Hap2 of PPARD and Hapl4 of PPARG in Phlegm-wetness, were significantly different from those in Normality, suggesting those might be group-associated haplotypes. These results suggested that single SNP and haplotypes ofPPARD, PPARG and APM1 may underlie the genetic basis of the constitutions classified in TCM.展开更多
