We examined the association of six SNP loci, rs6813195 near TMEM154, rs9505118 in SSR1, rs17106184 in FAF1, rs3130501 in POU5F1, rs702634 in ARL15, and rs4275659 near MPHOSPH9, identified by transethnic GWAS meta-analysis with susceptibility to type 2 diabetes in a Japanese population. This evidence concerns the gene POU5F1 and type 2 diabetes mellitus.
