Transforming growth factor-β induced gene corneal dystrophies (TGFBI; OMIM 601692) are a heterogeneous group of dystrophies, including epithelial basement membrane corneal dystrophy (EBMD; OMIM 121820), Bowman’s layer dystrophies: Thiel-Behnke corneal dystrophy (TBCD; OMIM 602082), Reis-Bűcklers – granular corneal dystrophy type III (GCD3; OMIM 608470), and the stromal dystrophies: lattice corneal dystrophy type I (LCDI; OMIM 122200) and variants (LCDvariants), granular corneal dystrophy type I (GCDI, OMIM 121900) and II (granular-lattice, Avellino – GCD2; OMIM 607541). Here, TGFBI is linked to Thiel-Behnke corneal dystrophy.
