A research team based at the University of Regensburg, Germany have developed a genetic risk score (GRS) for age related macular degeneration based on thirteen (13) risk variants from eight (8) gene loci. The research presents a useful risk model for AMD based on a large and well-characterized AMD case control group comprising 986 cases and 796 controls. The model provides a five-category classification system permitting the discrimination of individuals at high and low genetic risk.
