Funkcija

uredi

Ovaj gen je član nadporodice kadherina. Članovi porodice kodiraju proteine integralne membrane koji posreduju kalcij-ovisnoj adheziji. Proteinski proizvod ovog gena sastoji se od signalog peptida, 11 vanćelijskih domena koji vezuju kalcij, transmembranskog domena i jedinstvenog citoplazmatskog domena. Ima bitnu ulogu u održavanju normalnih funkcija mrežnjače l i pužnice.[7] Smatra se da je u interakciji s CDH23, kako bi formirao vrh-linkovane filamente.[9]

Klinički znčaj

uredi

Mutacije u ovom genu povezane su s gubitkom sluha, što je u skladu s njegovom lokacijom u Usherovom sindromu tip 1F (USH1F), kritičnoj regiji na hromosomu 10.[7] Utvrđeno je da su varijacije unutar njega povezane s normalnim razlikama u izgledu ljudskog lica.[10]
