Funkcija
urediOvaj gen kodira protein koji je uključen u biosintezu glikozilfosfatidilinozitolskog (GPI) sidra. GPI sidro je glikolipid koji se nalazi na mnogim krvnim ćelijama i služi za sidrenje proteina na njihovoj površini. Ovaj protein se eksprimira se u endoplazmatskom retikulumu i prenosi fosfoetanolamin (EtNP) u prvu manozu sidra GPI.
Klinički značaj
urediMutacije u PIGN uzrokuju prirođenu dijafragmatsku kilu.[7]
