Funkcija
urediOvaj gen je član porodice koneksinskih gena. Kodirani protein je komponenta uskih spojeva, koji se sastoje od niza međućelijskih kanala koji obezbjeđuju put za difuziju materijala male molekulske težine od ćelije do ćelije. Mutacije ovog gena mogu uzrokovati nesindromsku gluhoću ili kožni poremećaj zvani erythrokeratodermia variabilis. Alternativna prerada rezultira višestrukim varijantama transkripta koje kodiraju isti protein.[7]
