SNCA and Parkinson disease: To validate the implication for SNCA‐AS1 in PD, we assessed its expression in PD‐related datasets (Dumitriu et al., 2016; Nido et al., 2020; Schulze et al., 2018) and we found that in all analyzed conditions (PD brain frontal cortex, PD iPSCs, and PD mature neurons) SNCA‐AS1 was upregulated (Figure 5d).
