Probable transcription factor which exert its primary action widely during early neural development and in a very limited set of neurons in the mature brain.Defects in POU3F4 are a cause of deafness X-linked type 2 (DFNX2) . A mixed type of deafness characterized by both conductive hearing loss resulting from stapes (perilymphatic gusher) fixation and progressive sensorineural deafness.
