FTO and type 2 diabetes mellitus: Following the development of GPU-based GMDR-GPU program, we analyzed WTCCC dataset for T2D phenotype and our obtained results not only confirmed some earlier findings (such as the well-documented associations of TCF7L2, TSPAN8, and FTO variants with T2D) but also identified three more susceptibility genes (i.e., L3MBTL3, CELF4, and RUNX1) that have not been associated with T2D before.
