ADIPOQ is composed of three exons and harbors numerous single nucleotide polymorphisms (SNPs) that have been extensively studied in different populations [52,53], with several of these variants showing associations with alterations in adiponectin levels and metabolic syndrome-related phenotypes [33,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,51,54,55,56,57,58,59,60,61,62,63,64]. This evidence concerns the gene ADIPOQ and metabolic syndrome.
