A recent study by our group reported that the knockout of the core‐clock genes BMAL1 and NR1D1 resulted in altered expression of SNCA (upregulation and downregulation, respectively), encoding for α‐synuclein considered as one of the hallmark proteins for the PD pathology (Yalçin et al., 2021). The gene discussed is BMAL1; the disease is Parkinson disease.
