Rožnjačna distrofija Bowmanovog sloja tip I (Reis-Bücklerova rožnjačna distrofija.
Pod svjetlosnim mikroskopom, u rožnjači vide se obojeni depoziti karakterističnog proteina TGFBI na površini rožnjačne strome (Massonova trihromska boja)

Funkcija

Ovaj gen kodira protein RGD – koji se veže za kolagenske tipove I, II i IV. RGD motiv se nalazi u mnogim proteinima vanćelijskog matriksa moduliraju ćelijsku adheziju i služi kao sekvenca prepoznavanja liganda za nekoliko integrina. Ovaj protein ima ulogu u interakciji ćelija-kolagen i može biti uključen u stvaranje endohondrijskih kostiju u stvaranju hrskavice. Protein inducira transformirajući faktor rasta-beta i djeluje tako da inhibira ćelijsku adheziju.^[5]

Klinički značaj

Mutacije ovog gena uzrokuju nekoliko oblika rožnjačne distrofije.^[8][9]
