We compiled a list of mouse homologs of genes implicated by previous PD GWAS (Nalls et al., 2014, 2019; Chang et al., 2017) and genes with PARK designations and then performed a correlation analysis of the cell-type-specific distribution of these genes concerning Snca. Genes with positive correlations with p-values <0.05 are shown in Figure 3A. This evidence concerns the gene SNCA and Parkinson disease.
