[Genome-wide association in type 2 diabetes and its clinical application]

Diabetes mellitus is a complex and chronical disease, which represents one of the biggest health issues the world, with alarming numbers and constantly increasing it demands the creation of new diagnostic, therapeutic and preventive techniques. The complete Genome Wide Association (GWA) in type 2 diabetes (T2D) is a useful research tool for the characterization of genetic markers and physiopathogenic pathways, with potential clinical utility either as a T2D risk prediction or its complications. In Mexico is necessary to make a comprehensive dissection of the genetic background of T2D by the complex genetic mosaic of our population and increase the knowledge of the molecular and pathophysiological mechanisms that lead to this condition. There are several genetic studies for the Mexican population, linked to the 1000 genomes project, which have led to define some specific genetic markers for our population which are not described in European populations, until the moment, 78 loci have been associated with T2D. Recently in the global meta-analysis, with the participation of Mexico, we demonstrated at least 7 new variants associated with T2D.
