Summaries for NIPA1 Gene

Entrez Gene Summary for NIPA1 Gene

  • This gene encodes a magnesium transporter that associates with early endosomes and the cell surface in a variety of neuronal and epithelial cells. This protein may play a role in nervous system development and maintenance. Multiple transcript variants encoding different isoforms have been found for this gene. Mutations in this gene have been associated with autosomal dominant spastic paraplegia 6. [provided by RefSeq, Nov 2008]

GeneCards Summary for NIPA1 Gene

NIPA1 (Non Imprinted In Prader-Willi/Angelman Syndrome 1) is a Protein Coding gene. Diseases associated with NIPA1 include spastic paraplegia 6, autosomal dominant and spastic paraplegia 6. GO annotations related to this gene include magnesium ion transmembrane transporter activity. An important paralog of this gene is NIPAL3.

UniProtKB/Swiss-Prot for NIPA1 Gene

  • Acts as a Mg(2+) transporter. Can also transport other divalent cations such as Fe(2+), Sr(2+), Ba(2+), Mn(2+) and Co(2+) but to a much less extent than Mg(2+) (By similarity).

Disorders for NIPA1 Gene

(1) OMIM Diseases for NIPA1 Gene (608145)


  • Spastic paraplegia 6, autosomal dominant (SPG6) [MIM:600363]: 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:14508710, ECO:0000269 PubMed:15643603}. Note=The disease is caused by mutations affecting the gene represented in this entry.
