TACSTD2 and gelatinous drop-like corneal dystrophy: Genomic alterations of the human TROP2 were shown to cause a rare genetic disease, whereby TACSTD2 mutations induce an amyloid corneal dystrophy (Gelatinous Drop-like Corneal Dystrophy, GDLD) (35), while other organs that host Trop-2-expressing epithelia remain devoid of amyloid deposits.
