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). The gene discussed is KCNA3; the disease is Parkinsonism.
