    What are the genetic changes related to lattice corneal dystrophy type I ?
    ### Response:
    Lattice corneal dystrophy type I is caused by mutations in the TGFBI gene. This gene provides instructions for making a protein that is found in many tissues throughout the body, including the cornea. The TGFBI protein is part of the extracellular matrix, an intricate network that forms in the spaces between cells and provides structural support to tissues.
