TGFBI and granular corneal dystrophy type II: Depending upon deposition features and locations in the corneal layers, disease-causing mutations identified in the TGFBI gene have been involved in various phenotypes, including Thiel–Behnke corneal dystrophy (TBCD, OMIM 602082), Reis–Bucklers corneal dystrophy (RBCD, OMIM 608470), Groenouw type I granular cornea dystrophy (CDGG1, also known as GCD1, OMIM 121900), Avellino corneal dystrophy (ACD, OMIM 607541), lattice corneal dystrophy types I and IIIA (LCD1, OMIM 122200 and LCD3A, OMIM 608471), and epithelial basement membrane corneal dystrophy (EBMD, OMIM 121820) [2, 4, 17].
