SLC23A2 and open-angle glaucoma: We observed that in POAG cases (not in controls), the rs737723 polymorphism in SEC14L2/TAP was associated at the nominal level (p<0.05) with lower plasma vitamin E concentrations (10.0±0.35 μg/mL in CC versus 10.9±0.17 μg/ml in CG or GG subjects for the rs737723; p=0.045) only in the subgroup of POAG cases with the GG genotype for the rs1279683 polymorphism in the SLC23A2 gene.
