Notably, among published PD and AD risk genes (Supplementary Data 2), we found four PD risk genes (SH3GL2, LRRK2, SATB1, BST1)29,30, and an Alzheimer’s disease risk gene (CR1)31, which were highly expressed in these vulnerable DaNs subclusters (Supplementary Fig. 8d). The gene discussed is BST1; the disease is early-onset autosomal dominant Alzheimer disease.
