CYP4V2 (Cytochrome P450 Family 4 Subfamily V Member 2) is an enzyme that participates in fatty acid and lipid metabolism, including the production of fatty acid epoxides involved in blood pressure regulation and inflammation control. Variants in CYP4V2 are linked to Bietti’s crystalline dystrophy, a rare retinal disorder that can cause progressive vision loss, underscoring its importance in both lipid processing and eye health.
