BST1 rs4698412 was considered as a candidate SNP for risk of PD supported by several GWAS7, 14 and a meta‐analysis,13 but some other studies also indicated that there was no relationship between BST1 rs4698412 and PD.34, 38 We hypothesized that the discrepancy might be attributed to heterogeneity of individuals from different populations or experimental methods among studies. Here, BST1 is linked to Parkinson disease.
