The present invention provides an antisense
oligonucleotide pharmaceutical composition for preventing or treating Avellino corneal dystrophy, which induces the suppression of R124H
mutant TGFBI
protein expression, its use, or a method for treating the same. In particular, the present invention selectively acts on R124H TGFBI mRNA, which is a precursor to the production of R124H
mutant TGFBI
protein, the causative
protein of Avellino corneal dystrophy, thereby minimizing the effect on normal WT TGFBI expression and inducing the inhibition of R124H TGFBI expression, thereby enabling highly effective prevention or treatment of Avellino corneal dystrophy.
