SMARCA4 and Parkinson disease: Using bioinformatics analysis of large‐scale human transcriptomic data and Drosophila disease models, Sun et al. identified novel Parkinson's disease (PD) genes and revealed a potential common pathogenic signaling pathway consisting of the chromatin‐remodeling factor SMARCA4 and the ERK‐ETS signaling axis in normal aging and age‐related disorders such as PD.
