Purpose: To investigate the association between the CFH and ARMS2 gene polymorphisms and age-related macular degeneration (AMD) in a Brazilian cohort.
Methods: We examined 163 individuals with AMD and 154 controls recruited at the Department of Ophthalmology of the Universidade Federal de Minas Gerais, at the Instituto da Visão, and at the Centro Especializado em Olhos, in Brazil, between 2007 and 2012. Genotyping for CFH rs1061170 and ARMS2 rs10490924 single-nucleotide polymorphisms was performed.
Purpose: To investigate the association between VEGF gene polymorphism and age-related macular degeneration (AMD) in a Brazilian cohort.
Methods: We examined 160 affected individuals and 140 sex- and age-matched controls recruited at the Vision Institute and the Retina Department, São Geraldo Hospital, Minas Gerais Federal University, Brazil, between 2007 and 2011. Genotyping for the VEGF rs1413711 single nucleotide polymorphism (SNP) (+674C>T) was performed.
Age-related macular degeneration (AMD) is the most frequent cause of irreversible blindness in the elderly in developed countries. Although the etiology of AMD remains largely unknown, numerous studies have suggested that both genes and environmental risk factors significantly influence the risk of developing AMD. Recently, single nucleotide polymorphisms, DNA sequence variations found within the complement factor H (CFH) gene, have been found to be strongly associated with the development of AMD.
