CFB and age-related macular degeneration: The current literature suggests that risk alleles of genes ARMS2, CFH, and SNPs in C2/CFB rs641153, C3 rs2230199, C2/CFB rs4151667 are linked with late AMD (Table A1 and Table A2 in the Appendix A), and that high risk is attributable to the one SNP of ARMS2 and the five SNPs of CFH (Table A2) [15,16,17,18,19] that we have considered in this study.
