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

What is the official name of the OPTN gene?

The official name of this gene is “optineurin.”

OPTN is the gene's official symbol. The OPTN gene is also known by other names, listed below.

What is the normal function of the OPTN gene?

From NCBI GeneThis link leads to a site outside Genetics Home Reference.:

This gene encodes the coiled-coil containing protein optineurin. Optineurin may play a role in normal-tension glaucoma and adult-onset primary open angle glaucoma. Optineurin interacts with adenovirus E3-14.7K protein and may utilize tumor necrosis factor-alpha or Fas-ligand pathways to mediate apoptosis, inflammation or vasoconstriction. Optineurin may also function in cellular morphogenesis and membrane trafficking, vesicle trafficking, and transcription activation through its interactions with the RAB8, huntingtin, and transcription factor IIIA proteins. Alternative splicing results in multiple transcript variants encoding the same protein. [provided by RefSeq, Jul 2008]

From UniProtThis link leads to a site outside Genetics Home Reference.:

Plays an important role in the maintenance of the Golgi complex, in membrane trafficking, in exocytosis, through its interaction with myosin VI and Rab8. Links myosin VI to the Golgi complex and plays an important role in Golgi ribbon formation. Negatively regulates the induction of IFNB in response to RNA virus infection. Plays a neuroprotective role in the eye and optic nerve. Probably part of the TNF-alpha signaling pathway that can shift the equilibrium toward induction of cell death. May act by regulating membrane trafficking and cellular morphogenesis via a complex that contains Rab8 and hungtingtin (HD). May constitute a cellular target for adenovirus E3 14.7, an inhibitor of TNF-alpha functions, thereby affecting cell death.

How are changes in the OPTN gene related to health conditions?

Genetics Home Reference provides information about amyotrophic lateral sclerosis, which is associated with changes in the OPTN gene.
UniProtThis link leads to a site outside Genetics Home Reference. provides the following information about the OPTN gene's known or predicted involvement in human disease.

Glaucoma 1, open angle, E (GLC1E): A form of primary open angle glaucoma (POAG). POAG is characterized by a specific pattern of optic nerve and visual field defects. The angle of the anterior chamber of the eye is open, and usually the intraocular pressure is increased. However, glaucoma can occur at any intraocular pressure. The disease is generally asymptomatic until the late stages, by which time significant and irreversible optic nerve damage has already taken place.[1]This link leads to a site outside Genetics Home Reference. The disease is caused by mutations affecting the gene represented in this entry.

Glaucoma, normal pressure (NPG): A primary glaucoma characterized by intraocular pression consistently within the statistically normal population range.[2]This link leads to a site outside Genetics Home Reference. Disease susceptibility is associated with variations affecting the gene represented in this entry.

Amyotrophic lateral sclerosis 12 (ALS12): A neurodegenerative disorder affecting upper motor neurons in the brain and lower motor neurons in the brain stem and spinal cord, resulting in fatal paralysis. Sensory abnormalities are absent. The pathologic hallmarks of the disease include pallor of the corticospinal tract due to loss of motor neurons, presence of ubiquitin-positive inclusions within surviving motor neurons, and deposition of pathologic aggregates. The etiology of amyotrophic lateral sclerosis is likely to be multifactorial, involving both genetic and environmental factors. The disease is inherited in 5-10% of the cases.[3]This link leads to a site outside Genetics Home Reference. The disease is caused by mutations affecting the gene represented in this entry.
