In addition to the well‐characterized single mutation p.G156S in the GIRK2 (Kir3.2) channel, which induces parkinsonism in mice (Liss et al., 1999; Navarro et al., 1996), several other potassium channels including KV1.3, KV2.1 and Kir6.1, have been associated with PD (Chen et al., 2023). This evidence concerns the gene KCNA3 and Parkinson disease.
