Abstract
Purpose : Since the advent of genomic approaches, many chromosomal regions and polymorphisms have been associated with age-related macular degeneration (AMD). However, most of the disease variability might not be still captured by current researched genetic markers due to power issues. We have evidence that at least one component of the sarcoglycan-sarcospan protein complex (Sg-Sspn) gene is associated with increased odds of geographic atrophy (GA) AMD. Moreover, the retina of the knocked-out mouse model for the Sg-Sspn phenotypically resembles GA. Here, we aimed to explore the genome-wide association of the Sg-Sspn complex gene regions with AMD.
