Corneal dysmorphologies (CDs) are a group of acquired but predominantly genetically inherited eye disorders that cause progressive vision loss and can be associated with systemic abnormalities. This study aimed to identify candidate CD genes in humans by looking at knockout mice with targeted deletions of orthologous genes that exhibited statistically significant corneal abnormalities. Analysis of data from 8,707 knockout mouse lines identified 213 candidate CD genes; 176 (83%) genes have not been implicated previously in CD. Bioinformatic analyses implicated candidate genes in several signaling pathways (e.g., integrin signaling pathway, cytoskeletal regulation by Rho GTPase, FAS signaling pathway), which are potential therapeutic targets.
