Abstract
Purpose: To determine if the frequency of the MMP-2 (-1306 C/T) genotype has an influence on the development of early age-related macular degeneration (AMD).
Methodology: The study enrolled 387 patients with early AMD and a random sample of 682 healthy persons (control group). The genotyping of MMP-2 (-1306 C/T) was carried out using the real-time polymerase chain reaction method.
Results: The analysis of the MMP-2 (-1306 C/T) gene polymorphism did not reveal any differences in the genotype distribution between the patients with AMD and the control subjects. When the study population was divided into age groups, the C/C genotype was more prevalent in the AMD patients aged <65 years than those aged ≥65 years (65.19% versus 53.88%, p = 0.0294), and the C/T genotype was more frequent in the AMD patients aged ≥65 years when compared with the AMD patients aged <65 years (40.78% versus 26.52%, p = 0.0037). Moreover, in the female group younger than 65 years, the frequency of the C/C genotype was greater in the AMD group than the control group (75% versus 58.91%, p = 0.0232).
Conclusions: This study showed a significantly greater prevalence of the C/C and C/T genotypes in the patients with AMD younger than 65 years and those aged ≥65 years, respectively. Moreover, the AMD women aged <65 years were the carriers of the C/C genotype significantly more frequently than their control counterparts.
