In the AMD cybrids, there were significant decreases in the protein levels for the CFH (Isoform 1; 21%, P = 0.03); CFHL1 (Isoform 2; 33%, P = 0.001); CD55 (76%, P = 0.04); CD59 (79%, P = 0.048); CD46 (78%, P = 0.04) and CFI (36%, P = 0.003), compared to Older-Normal cybrids that had been normalized to 100%. This evidence concerns the gene CFH and age-related macular degeneration.
