HTRA1 and age-related macular degeneration: Further analysis showed no significant differences in HTRA1 and ARMS2 expressions in AMD retinas that were heterozygous for rs10490924, del443ins54, and rs11200638 (ARMS2, fold change average=0.943, p=0.771; HTRA1, fold change average=0.953, p=0.769), and heterozygous rs2736911 (ARMS2, fold change average=1.133, p=0.383; HTRA1, fold change average=1.084, p=0.685) compared to normal retinas with the common alleles (Figure 1B,C).
