	abstract = {BACKGROUND: Age-related macular degeneration (AMD) is a degenerative ocular disease, which may lead to loss of central vision. In Caucasian populations, a strong correlation has been established with polymorphism Y402H (rs1061170) in the complement factor H gene (CFH). The H131R polymorphism (rs1801274) in the FCGR2A gene has been associated with many inflammatory diseases, but has not been investigated in relation to AMD. The goal of our study was the development of a novel method for Y402H (g.43097C>T) genotyping, the confirmation of its association with AMD in the Greek population and the investigation of the H131R polymorphism in AMD. METHODS: DNAs were extracted from blood samples of 120 patients with the severe wet form of AMD and 103 age- and sex-matched controls, all of whom were clinically evaluated. A real-time PCR and melting curve analysis method for Y402H genotyping was developed in the LightCycler platform, after in silico design of appropriate primers and probes. Genotyping for H131R was performed using a real-time PCR method previously described by our group. RESULTS: The novel genotyping method for Y402H in the CFH gene is fast, reproducible (Efficiency=1.79, reproducibility CVCq=3.33\%, Tm C allele 53.36 degrees C and T allele 61.91 degrees C, DeltaTm=8.55) and accurate as results were confirmed with the gold standard DNA Sequencing method. CONCLUSIONS: The present study confirmed the association between CFH Y402H SNP and wet AMD in the Greek population (OR=1.77, p=0.002). FCGR2A H131R polymorphism was investigated for the first time in this present study for possible correlation with wet AMD and a statistically significant association was detected (OR=1.74, p=0.006), that awaits further confirmation in a larger set of samples},
