Lizozomalna alfa-glukozidaza je enzim koji je kod ljudi kodiran GAA genom.[1]

Kisela alfa-glukozidaza je esencijalna za degradaciju glikogena do glukoze u lizozomima. Različite forme kisele alfa-glukozidaze nastaju putem proteolitičke obrade. Tri transkriptne varijante koje kodiraju isti protein su poznate.[1]

Mutacije ovog gena uzrokuju glikogenozu tipa II (Pompeovu bolest). To je autozomno recesivno oboljenje sa širokim kliničkim spektrom.
