Abstract

Purpose: To investigate tumor necrosis factor (TNF)-α gene polymorphisms in advanced dry-type age-related macular degeneration (AMD) in a population from Northeastern Iran. Methods: In this case-control study, 50 patients with geographic macular atrophy and 73 gender-matched controls were enrolled. Genomic deoxyribonucleic acid (DNA) was extracted from the peripheral blood. Polymerase chain reaction was performed to analyze 2 candidate single nucleotide polymorphisms in the TNF-α gene, namely -1031 thymine (T)/cytosine (C) and -308 guanine (G)/adenine (A). Results: The distribution of the - 1031 T/C genotype was TT, 62; TC, 36; CC, 2 in the patients and TT, 60; TC, 36; CC, 4 in the controls (P = 0.94). Genotype analysis of TNF-α -308 also revealed no significant difference in distribution between patients (G, 78; GA, 22; AA, 0) and controls (GG, 74; GA, 23; AA, 3) (P = 0.51). None of the haplotypes nor alleles of studied TNF-α polymorphisms were significantly associated with advanced dry-type AMD. Conclusion: The findings of this study show that polymorphisms in the TNF-α gene, do not play an important role in dry-type AMD in the studied population. © 2015 Journal of Ophthalmic and Vision Research.
