SPTAN1 GeneProduct ensembl:ENSG00000197694 Pathogenic SPTAN1 (human gene encoding spectrin) variants cause early infantile epileptic encephalopathy type 5, an infantile epileptic encephalopathy with diffuse hypomyelination, brain atrophy and developmental retardation. Subsequent studies of these human variants, as well as studies using mice with conditional knockout of spectrin all show disruptions in AIS structure and neuronal excitability so, SPTAN1 maintains AIS integrity and supports Na-channel organization and neuronal excitability in normal states.
