What is the official name of the ERLIN2 gene?

The official name of this gene is “ER lipid raft associated 2.”

ERLIN2 is the gene's official symbol. The ERLIN2 gene is also known by other names, listed below.

What is the normal function of the ERLIN2 gene?

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

This gene encodes a member of the SPFH domain-containing family of lipid raft-associated proteins. The encoded protein is localized to lipid rafts of the endoplasmic reticulum and plays a critical role in inositol 1,4,5-trisphosphate (IP3) signaling by mediating ER-associated degradation of activated IP3 receptors. Mutations in this gene are a cause of spastic paraplegia-18 (SPG18). Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Feb 2012]

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

Component of the ERLIN1/ERLIN2 complex which mediates the endoplasmic reticulum-associated degradation (ERAD) of inositol 1,4,5-trisphosphate receptors (IP3Rs). Also involved in ITPR1 degradation by the ERAD pathway.

How are changes in the ERLIN2 gene related to health conditions?

Genetics Home Reference provides information about juvenile primary lateral sclerosis, which is associated with changes in the ERLIN2 gene.
UniProtThis link leads to a site outside Genetics Home Reference. provides the following information about the ERLIN2 gene's known or predicted involvement in human disease.

Spastic paraplegia 18, autosomal recessive (SPG18): 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. SPG18 is a severe form with onset in early childhood. Most affected individuals have severe psychomotor retardation. Some may develop significant joint contractures.[1]This link leads to a site outside Genetics Home Reference. The disease is caused by mutations affecting the gene represented in this entry.

NCBI GeneThis link leads to a site outside Genetics Home Reference. lists the following diseases or traits (phenotypes) known or believed to be associated with changes in the ERLIN2 gene.
