  • rs1057910(C;C) genotypes may clear drugs like celecoxib (trade name Celebrex) twice as slowly as rs1057910(A;A) genotypes; the rs1057910(A;C) genotypes are in-between clearance rates. Lower clearance rates will lead to higher internal concentrations of the drug. It is not clear whether this could lead to increased efficacy and/or increased side effects. [PMID 12893985]
  • rs1057910(C;C) genotypes are poor metabolizers of glipizide, a second generation sulfonylurea drug structurally similar to tolbutamide and also used as an oral hypoglycemic agent. [PMID 10208645]
