In the MIRO1 and SNCA datasets, the GFAP and S100b glial markers from imaging data shared pathways with the cytoskeleton filament-associated STMN1 and GFAP genes, suggesting that glial cell development or maturity might be affected in these forms of PD (Supplementary Fig. 3a, b). The gene discussed is S100B; the disease is Parkinson disease.
