PPARA and age-related macular degeneration: Of particular interest were genes related to lipid oxidation (PPARA, SUMF2, HMGCS3), low-density lipoprotein metabolism (LDLRAD3) and cholesterol excretion (SLC51A), and a second Solute Carrier Family (SLC) gene, monocarboxylic acid transporter SLC16A8, previously implicated in age-related macular degeneration.
