Association of polymorphisms of complement factor I rs141853578 (G119R) with age-related macular degeneration in Iranian population

摘要

Background Age-related macular degeneration (AMD) is a complex disease, and recent studies have shown role of complement system genes in its development. Complement factor I regulates the complement pathways, and relationship between CFI polymorphisms and AMD is controversial. We evaluated the possible association of complement factor I rs141853578 (G119R) variation with advanced AMD in Iranian patients. Materials and methods We included 371 case-control samples consisting of 220 advanced AMD patients and 151 genetically unrelated healthy controls. Extracted DNA samples amplified to obtain fragment including the polymorphic complement factor I rs141853578 (G119R) region.
