Summaries for ATL1 Gene

Entrez Gene Summary for ATL1 Gene

  • The protein encoded by this gene is a GTPase and a Golgi body transmembrane protein. The encoded protein can form a homotetramer and has been shown to interact with spastin and with mitogen-activated protein kinase kinase kinase kinase 4. This protein may be involved in axonal maintenance as evidenced by the fact that defects in this gene are a cause of spastic paraplegia type 3. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

GeneCards Summary for ATL1 Gene

ATL1 (Atlastin GTPase 1) is a Protein Coding gene. Diseases associated with ATL1 include neuropathy, hereditary sensory, type id and spastic paraplegia 3a, autosomal dominant. Among its related pathways are Cytoskeletal Signaling and Interferon Signaling. GO annotations related to this gene include identical protein binding and GTPase activity. An important paralog of this gene is ATL2.

Disorders for ATL1 Gene

  • Spastic paraplegia 3, autosomal dominant (SPG3) [MIM:182600]: A form of spastic paraplegia, a neurodegenerative disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. Rate of progression and the severity of symptoms are quite variable. Initial symptoms may include difficulty with balance, weakness and stiffness in the legs, muscle spasms, and dragging the toes when walking. In some forms of the disorder, bladder symptoms (such as incontinence) may appear, or the weakness and stiffness may spread to other parts of the body. {ECO:0000269 PubMed:11685207, ECO:0000269 PubMed:12112092, ECO:0000269 PubMed:12939451, ECO:0000269 PubMed:14695538, ECO:0000269 PubMed:15184642, ECO:0000269 PubMed:16533974, ECO:0000269 PubMed:17427918, ECO:0000269 PubMed:20718791, ECO:0000269 PubMed:20932283, ECO:0000269 PubMed:21336785, ECO:0000269 PubMed:23483706, ECO:0000269 PubMed:24473461}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Neuropathy, hereditary sensory, 1D (HSN1D) [MIM:613708]: A disease characterized by adult-onset distal axonal sensory neuropathy leading to mutilating ulcerations as well as hyporeflexia. Some patients may show features suggesting upper neuron involvement. {ECO:0000269 PubMed:21194679}. Note=The disease is caused by mutations affecting the gene represented in this entry.
