Entrez Gene Summary for REEP1 Gene

  • This gene encodes a mitochondrial protein that functions to enhance the cell surface expression of odorant receptors. Mutations in this gene cause spastic paraplegia autosomal dominant type 31, a neurodegenerative disorder. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2009]

Disorders for REEP1 Gene

(2) OMIM Diseases for REEP1 Gene (609139)


  • Spastic paraplegia 31, autosomal dominant (SPG31) [MIM:610250]: 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:16826527, ECO:0000269 PubMed:18644145, ECO:0000269 PubMed:20718791, ECO:0000269 PubMed:21618648, ECO:0000269 PubMed:24478229}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Neuronopathy, distal hereditary motor, 5B (HMN5B) [MIM:614751]: A disorder characterized by distal muscular atrophy mainly affecting the upper extremities, in contrast to other distal motor neuronopathies. These constitute a heterogeneous group of neuromuscular diseases caused by selective degeneration of motor neurons in the anterior horn of the spinal cord, without sensory deficit in the posterior horn. The overall clinical picture consists of a classical distal muscular atrophy syndrome in the legs without clinical sensory loss. The disease starts with weakness and wasting of distal muscles of the anterior tibial and peroneal compartments of the legs. Later on, weakness and atrophy may expand to the proximal muscles of the lower limbs and/or to the distal upper limbs. HMN5B is characterized by onset in the first or second decade of distal muscle weakness and atrophy, primarily affecting the intrinsic hand muscles, but also affecting the lower legs, resulting in abnormal gait and pes cavus. {ECO:0000269 PubMed:22703882}. Note=The disease is caused by mutations affecting the gene represented in this entry.
