Drago, A., 2016		Freq(Significant SNPs/total SNPs%)=0.13. Encodes for a subunit of Phosphatidylinositol 3-kinase enzyme which is necessary for the insulin-stimulated increase in glucose uptake and glycogen synthesis in insulin-sensitive tissues. Plays an important role in signaling in response to FGFR1, FGFR2, FGFR3, FGFR4, KITLG/SCF, KIT, PDGFRA and PDGFRB. Likewise, plays a role in ITGB2 signaling.	Positive	Comment on Study
