Figure 1. Ethidium bromide-stained 2% agarose gels and direct sequencing, showing the PCR-restriction fragment length polymorphism and corresponding sequence chromatogram. A: Restriction analysis for complement factor H (CFH) Y402H polymorphism resulted in digestible fragment (T/T), undigestible fragment (C/C), and heterozygote (T/C). B: Direct sequencing of the PCR products confirmed the restriction patterns for CFH Y402H. C: Restriction analysis for LOC387715rs10490924 resulted in digestible fragment (G/G), undigestible fragment (T/T), and heterozygote (T/G). D: Sequencing confirmed the restriction patterns for LOC387715rs10490924. E: Restriction analysis for HTRA1rs11200638 resulted in digestible fragment (G/G), undigestible fragment (A/A), and heterozygote (G/A). F: Sequencing confirmed the restriction patterns for HTRA1rs11200638.
