Abstract

DESCRIPTION (provided by applicant): We will build upon the established and recently identified genetic loci and environmental and ocular determinants, to incorporate newly discovered loci for age-related macular degeneration (AMD) identified in this proposal for gene-gene, gene-environment, and predictive modeling analyses. We also propose to assess the full spectrum of rare, potentially functional variants, as well as common variants in candidate genes/regions by targeted sequencing. The discovery of causal variants in associated genes will improve the understanding of the underlying mechanisms of AMD development and progression. Knowledge of causal variants will lead to more accurate definitions and classification systems for AMD. We will expand our unique databases to accomplish the scientific aims of the study and to facilitate expanded collaborative efforts with other investigators. We will also conduct functional studies to define the mechanisms associated with the genetic variants. As a result of this effort, we anticipate that additional new pathogenic genetic pathways will be identified for this increasing cause of blindness. These potential discoveries will lead to novel therapeutic and preventive measures for preserving vision, and will reduce the burden of marked visual loss due to the advanced forms of AMD.
