In the largest GWAS meta-analysis of idiopathic PD (iPD) the nearby VAMP4 (vesicle-associated membrane protein 4) rs11578699, located 113,325 bp from DNM3 rs2421947, is associated with PD, raising the possibility that the effect of DNM3 may relate to linkage disequilibrium with VAMP4 (Nalls et al., 2019). Here, VAMP4 is linked to Parkinson disease.
