EGF-containing fibulin extracellular matrix protein 1 (EFEMP1), or fibulin-3, is an extracellular matrix glycoprotein encoded by the EFEMP1 gene. The role of EFEMP1 in the human eye is incompletely understood, but there are well-reported associations between mutations in the gene and a variety of ophthalmic diseases, such as myopia, juvenile open-angle glaucoma (JOAG), primary open-angle glaucoma (POAG) and familial drusen formation in Malattia Leventinese (ML)/Doyne honeycomb retinal dystrophy (DHRD). Variants which interact with EFEMP1 have also been identified in genome-wide association studies (GWAS) for age-related macular degeneration (AMD). Many of these conditions form a large component of ophthalmology case-load and have incompletely characterized pathogenesis. In this review, we will describe the role of EFEMP1 in ophthalmic disease. We discuss the role of EFEMP1 in Mendelian eye disease, its polygenic contributions to common ophthalmic conditions, and the potential to target EFEMP1 for therapeutic purposes.
