To investigate the effect of single nucleotide polymorphisms (SNPs) and haplotypes in the genes encoding age-related maculopathy susceptibility 2 (LOC387715/ARMS2) and high-temperature requirement A-1 (HTRA1) in a case-control study in a Chinese cohort of individuals with exudative age-related macular degeneration (AMD).
Understanding oxidative stress and HTRA1 locus in abnormal angiogenesis resulting in wet AMD pathology is an important step in developing a novel therapeutic approach.
We identified a sample of patients with neovascular AMD, that in previous studies had been shown to be at elevated risk for the disease through environmental factors such as cigarette smoking and genetic variants including the complement factor H gene (CFH) on chromosome 1q25 and variants in the ARMS2/HtrA serine peptidase 1 (HTRA1) gene(s) on chromosome 10q26.
