Background: The KCNKMAI gene encodes the alpha-subunit of the large conductance, voltage, and calcium-sensitive potassium channel (BK channels) that plays a critical role in neuronal excitability Heterozygous mutations in KCNMA1 were first illustrated in a large family with generalized epilepsy and paroxysmal nonkinesigenic dyskinesia. Recent research has established homozygous KCNAM1 mutations accountable for the phenotype of cerebellar atrophy, developmental delay, and seizures.
