Furthermore, individual target analyses only identified CACNA1H (OR: 1.431; 95% CI: 1.215–1.686; Adjusted p = 5.37E-04; per 10-mmHg lower) by “eQTL-based method” as a significant target that may drive the causal effect of CCB on PD risk (Supplementary Table S11). Here, CACNA1H is linked to Parkinson disease.
