TGFBI and corneal dystrophy: Corneal amyloidosis disorders, including gelsolin-related lattice corneal dystrophy type II (Finnish-type familial amyloid polyneuropathy type IV), lactoferrin-related familial subepithelial amyloidosis, transforming growth factor beta-induced gene (TGFBI)-related corneal dystrophies, and polymorphic amyloid degeneration, are characterized by phenotypic abnormal deposits accompanied by corneal opacities, epithelial abnormalities, pain, and potential loss of vision [4].
