This intersection of disease risk and DA neuron expression effect appears to be specific to DA neurons for TBC1D5 (Figure S26), CCAR2 (Figure 7B), and ARIH2 (Figure S27), whereas PRCP and CCDC58 (Figures S28 and S29) and CAMLG (Figure S30) showed signals that intersected PD risk signals in multiple cell types. This evidence concerns the gene PRCP and Parkinson disease.
