SLC23A2 and open-angle glaucoma: We observed a statistically significant (p<0.0125, after correction for multiple testing) association between the rs1279683 polymorphism in the vitamin C co-transporter (SLC23A2) and POAG risk (unadjusted OR 1.70, 95% CI 1.17–2.47, p=0.005) for GG homozygotes in comparison with carriers of the A allele after correction for multiple comparisons.
