Another AD‐risk gene is CD2AP which encodes for a protein involved in endocytosis and endosome's morphology (through interaction with Rab4) (Cormont et al., 2003; Gauthier et al., 2007), as well as in growth factor‐induced endocytosis (Kobayashi et al., 2004) and APP lysosomal trafficking (Furusawa et al., 2019). The gene discussed is APP; the disease is Alzheimer disease.
