Abstract

Fibulin-3 (F3) is a secreted, disulfide-rich glycoprotein which is expressed in a variety of tissues within the body, including the retina. An Arg345Trp (R345W) mutation in F3 was identified as the cause of a rare retinal dystrophy, Malattia Leventinese/Doyne Honeycomb Retinal Dystrophy (ML/DHRD). ML/ DHRD shares many phenotypic similarities with age-related macular degeneration (AMD). The most prominent feature of ML/DHRD is the development of radial or honeycomb patterns of drusen which can develop as early as adolescence. Two independent mouse models of ML/DHRD show evidence of complement activation as well as retinal pigment epithelium (RPE) atrophy, strengthening the phenotypic connection with AMD. Because of its similarities with AMD, ML/DHRD is receiving increasing interest as a potential surrogate disease to study the underpinnings of AMD. This mini-review summarizes the current knowledge of F3 and points toward potential therapeutic strategies which directly or indirectly target cellular dysfunction associated with R345W F3.
