Summaries for GNAO1 Gene

Entrez Gene Summary for GNAO1 Gene

  • The protein encoded by this gene represents the alpha subunit of the Go heterotrimeric G-protein signal-transducing complex. Defects in this gene are a cause of early-onset epileptic encephalopathy. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2015]

GeneCards Summary for GNAO1 Gene

GNAO1 (G Protein Subunit Alpha O1) is a Protein Coding gene. Diseases associated with GNAO1 include Neurodevelopmental Disorder With Involuntary Movements and Epileptic Encephalopathy, Early Infantile, 17. Among its related pathways are G-protein signaling G-Protein alpha-i signaling cascades and Apoptotic Pathways in Synovial Fibroblasts. Gene Ontology (GO) annotations related to this gene include GTP binding and obsolete signal transducer activity. An important paralog of this gene is GNAI1.

UniProtKB/Swiss-Prot for GNAO1 Gene

  • Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. The G(o) protein function is not clear. Stimulated by RGS14.

Tocris Summary for GNAO1 Gene

  • Heterotrimeric G proteins are membrane bound GTPases that are linked to 7-TM receptors. Each G protein contains an alpha-, beta- and gamma-subunit and is bound to GDP in the 'off' state. Ligand binding causes a receptor conformational change, detaching the G protein and switching it 'on'.

  • Epileptic encephalopathy, early infantile, 17 (EIEE17) [MIM:615473]: A severe neurologic disorder characterized by onset of intractable seizures in the first weeks or months of life and usually associated with EEG abnormalities. Affected infants have very poor psychomotor development and may have brain abnormalities, such as cerebral atrophy or thin corpus callosum. Some patients may show involuntary movements. {ECO:0000269 PubMed:23993195, ECO:0000269 PubMed:25966631, ECO:0000269 PubMed:26485252, ECO:0000269 PubMed:27476654, ECO:0000269 PubMed:27864847}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Neurodevelopmental disorder with involuntary movements (NEDIM) [MIM:617493]: A neurodevelopmental disorder manifesting with a wide range of clinical symptoms. Clinical features range from severe motor and cognitive impairment with marked choreoathetosis, self-injurious behavior and epileptic encephalopathy, to a milder phenotype featuring moderate developmental delay associated with complex stereotypies, mainly facial dyskinesia, and mild epilepsy. Hyperkinetic movements are often exacerbated by specific triggers, such as illness, emotion and high ambient temperature. Some patients have brain abnormalities, such as cerebral atrophy or thin corpus callosum. {ECO:0000269 PubMed:25966631, ECO:0000269 PubMed:26060304, ECO:0000269 PubMed:27068059, ECO:0000269 PubMed:27625011, ECO:0000269 PubMed:28357411}.
