This network is also related to important Alzheimer's disease susceptibility genes as the interactions culled from NCBI gene show that GGA1 binds to the sortilin-related receptor, SORL1, and the APP cleaving beta-secretase BACE2, while GGA2 binds to the beta-secretases BACE1 and BACE2,  SORL1 and the prolyl-isomerase PIN1. Here, APP is linked to early-onset autosomal dominant Alzheimer disease.
