ARHGEF9 gene

Cdc42 guanine nucleotide exchange factor 9

The information on this page was automatically extracted from online scientific databases.

From NCBI Gene:

The protein encoded by this gene is a Rho-like GTPase that switches between the active (GTP-bound) state and inactive (GDP-bound) state to regulate CDC42 and other genes. Defects in this gene are a cause of startle disease with epilepsy (STHEE), also known as hyperekplexia with epilepsy. Three transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Mar 2010]

From UniProt:

Acts as guanine nucleotide exchange factor (GEF) for CDC42. Promotes formation of GPHN clusters.

  • Early infantile epileptic encephalopathy 8

From UniProt:

Epileptic encephalopathy, early infantile, 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.
