Genome-wide association studies of refractive error and myopia, lessons learned, and implications for the future

Abstract

The investigation of the genetic basis of refractive error and myopia entered a new stage with the introduction of genome-wide association studies (GWAS). Multiple GWAS on many ethnic groups have been published over the years, providing new insight into the genetic architecture and pathophysiology of refractive error. This is a review of the GWAS published to date, the main lessons learned, and future possible directions of genetic studies of myopia and refractive error. © 2014 The Association for Research in Vision and Ophthalmology, Inc.
