Study on the association of transferrin receptor gene polymorphism with age related macular degeneration / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#AIM: To develop the correlation of patients in age-related macular degeneration and TFR2 gene polymorphism in the Han people of northeast China.<p>METHODS: Totally 200 patients with ARMD(dry-ARMD 100 individuals and wet-ARMD 100 individuals)and 100 healthy control people were chosen as the experiment team and control team. Peripheral venous blood were collected and anticoagulated dealed with EDTA. Then we extraced genome DNA and amplificate rs2075674, which was the polymorphic locus of TFR2 gene according to the primer sequences provided by references, for polymerase chain reaction(PCR). The group representativeness of samples is identified according to hardy Weinberg equilibrium principle. <p>RESULTS: We found that the difference between ARMD group and control group in the polymorphism of TFR2 gene rs2075674 is statistically significant(χ²=6.494, <i>P</i>=0.011). There was significant difference between the wet ARMD group and control group(χ²=11.054, <i>P</i>=0.001). There had no significant differences when it comes to the dry ARMD group and the control group(χ²=1.418, <i>P</i>=0.234).<p>CONCLUSION: The above findings indicate that polymorphism of TFR2 gene increases the risk of ARMD in the Han population of Northeast China. It is concluded that rs2075674 is significantly correlated with wet-ARMD.
