To investigate the association between the g.4235T>C (rs2337395) polymorphism of the UNG gene and the c.-31A>G (rs3087404) polymorphism of the SMUG1 gene and the risk of age-related macular degeneration (AMD), as well as modulation of this association by some environmental and lifestyle factors.
We observed that the g.4235T>C (rs2337395) and c.-32A>G (rs3087404) polymorphisms in two genes encoding such glycosylases, UNG and SMUG1, respectively, could be associated with the occurrence of AMD.
