The next probe (cg26074603) targets the 5′ UTR of KCNC2. This gene is a core regulator of the voltage-gated potassium channel and has been confirmed to participate in the pathogenesis of multiple diseases, including extratemporal epilepsy (Vetri et al., 2020) and spinocerebellar ataxia (Rajakulendran et al., 2013). The gene discussed is KCNC2; the disease is cerebellar ataxia.
