Notably, by an integrated analysis of the genotypes and the serum levels of APOA5, BUD13 and triglyceride, we observed that BUD13 was another potential mediator, besides APOA5, of the association between rs651821 and serum triglyceride. rs671 (ALDH2), an east Asian-specific common variant, was found to be associated with MetS (P<sub>combined</sub> = 9.7 × 10<sup>-22</sup> ) in Han Chinese.
Even after adjustment for MetS status, reduced abundances of Actinobacteria and <i>Bifidobacterium</i> were significantly linked to the minor allele at the <i>APOA5</i> SNP rs651821.
