Abstract

Background: Age-related macular degeneration (AMD) is the leading cause of blindness in the elderly individuals. The etiology of AMD includes environmental and genetic factors.

Methods: We aimed to determine the association between CETP (rs5882; rs708272; rs3764261; rs1800775; rs2303790), AGER (rs1800624; rs1800625), and CYP4F2 (rs1558139) gene polymorphisms and development of atrophic AMD. About 52 patients with atrophic AMD and 800 healthy control subjects were evaluated. The genotyping of single-nucleotide polymorphisms in CETP, AGER, and CYP4F2 was carried out using the real-time-PCR method.

Results: Genetic risk models in the analysis of CETP rs5882 revealed statistically significant variables with increased risk of atrophic AMD in the codominant (p < .001), dominant (p < .001), recessive (p < .001), and additive (p < .001) models with the highest 25.4-fold increased risk of atrophic AMD in the codominant model (p < .001). The AGER rs1800625 was associated with a highly increased risk of atrophic AMD in the codominant (p < .001), recessive (p < .001), and additive (p < .001) genetic models.

Conclusion: We identified two polymorphisms with a higher risk of atrophic AMD (CETP rs5882 and AGER rs1800625).

Keywords: AGER; CETP; CYP4F2; age-related macular degeneration; gene polymorphism.
