But rs2270968 of MCCC1 (P < .001, OR = 1.10; Figure 1B) and rs7479949 of DLG2 (P < .001, OR = 0.89; Figure 1C) which were not significantly associated with PD in allele model in our cohort still turned to be significant alleles for PD following the meta‐analysis. Here, MCCC1 is linked to Parkinson disease.
