    Susceptibility
  • to type 2 diabetes
  • to attention deficit hyperactivity disorder (Gizer 2009)
  • to decreased glucose-stimulated insulin response
    • Variant & Polymorphism SNP
  • a single-nucleotide polymorphism in the human ADRA2A gene for which risk allele carriers exhibited overexpression of alpha(2A)AR, reduced insulin secretion, and increased type 2 diabetes risk (Rosengren 2010)
  • variants at the DGKB/AGMO, ADRA2A, GLIS3 and C2CD4B loci were associated with decreased glucose-stimulated insulin response
