SOD2 and retinopathy of prematurity: Our findings regarding the association of the rs3877899A allele with ELGA are also in line with previous clinical studies in the Italian population, which demonstrated the association of SNPs in antioxidant enzymes with low GA and/or BW (for superoxide dismutase 2) as well as complications of prematurity, including ROP (for superoxide dismutase 1, 3, and catalase) [7,31].
