To our knowledge, alterations in brain glucose metabolism have not been investigated in people with KCNA1 epilepsy, which might be explained by the fact that loss of KCNA1 function in humans can manifest in many phenotypes of which ataxia is dominant and cerebellar hypometabolism has been reported in one patient (Kim et al., 2008). The gene discussed is KCNA1; the disease is cerebellar ataxia.
