ARHGEF9 Acts as guanine nucleotide exchange factor (GEF) for CDC42. Promotes formation of GPHN clusters. Defects in ARHGEF9 are the cause of pileptic encephalopathy, early infantile, type 8 (EIEE8). A disorder characterized by hyperekplexia and early infantile epileptic encephalopathy. Neurologic features include exaggerated startle response, seizures, impaired psychomotor development, and mental retardation. Seizures can be provoked by tactile stimulation or extreme emotion. 2 isoforms of the human protein are produced by alternative splicing.
