Name

OPA3 Gene

optic atrophy 3 (autosomal recessive, with chorea and spastic paraplegia)

The mouse ortholog of this protein co-purifies with the mitochondrial inner membrane. Mutations in this gene have been shown to result in 3-methylglutaconic aciduria type III and autosomal dominant optic atrophy and cataract. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2009]

SPG27 Gene

spastic paraplegia 27 (autosomal recessive)

SPG25 Gene

spastic paraplegia 25 (autosomal recessive, with disc herniation)

SPG24 Gene

spastic paraplegia 24 (autosomal recessive)

SPG21 Gene

spastic paraplegia 21 (autosomal recessive, Mast syndrome)

The protein encoded by this gene binds to the hydrophobic C-terminal amino acids of CD4 which are involved in repression of T cell activation. The interaction with CD4 is mediated by the noncatalytic alpha/beta hydrolase fold domain of this protein. It is thus proposed that this gene product modulates the stimulatory activity of CD4. Mutations in this gene are associated with autosomal recessive spastic paraplegia 21 (SPG21), also known as mast syndrome. Alternative splicing results in multiple transcript variants.

SPG23 Gene

spastic paraplegia 23 (autosomal recessive)

SPG20 Gene

spastic paraplegia 20 (Troyer syndrome)

This gene encodes a protein containing a MIT (Microtubule Interacting and Trafficking molecule) domain, and is implicated in regulating endosomal trafficking and mitochondria function. The protein localizes to mitochondria and partially co-localizes with microtubules. Stimulation with epidermal growth factor (EGF) results in protein translocation to the plasma membrane, and the protein functions in the degradation and intracellular trafficking of EGF receptor. Multiple alternatively spliced variants, encoding the same protein, have been identified. Mutations associated with this gene cause autosomal recessive spastic paraplegia 20 (Troyer syndrome).

SPG36 Gene

spastic paraplegia 36 (autosomal dominant)

SPG45 Gene

spastic paraplegia 45 (autosomal recessive)

SPG41 Gene

spastic paraplegia 41 (autosomal dominant)

This locus was defined in a Chinese family. Nineteen individuals were genotyped and the interval was defined between D11S1324 and D11S1933. [provided by RefSeq, Feb 2010]

SPG7 Gene

spastic paraplegia 7 (pure and complicated autosomal recessive)

This gene encodes a mitochondrial metalloprotease protein that is a member of the AAA family. Members of this protein family share an ATPase domain and have roles in diverse cellular processes including membrane trafficking, intracellular motility, organelle biogenesis, protein folding, and proteolysis. Mutations in this gene cause autosomal recessive spastic paraplegia 7. Two transcript variants encoding distinct isoforms have been identified. [provided by RefSeq, Mar 2014]

SPG9 Gene

spastic paraplegia 9 (autosomal dominant)

SPG11 Gene

spastic paraplegia 11 (autosomal recessive)

The protein encoded by this gene is a potential transmembrane protein that is phosphorylated upon DNA damage. Defects in this gene are a cause of spastic paraplegia type 11 (SPG11). Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2009]

SPG16 Gene

spastic paraplegia 16 (complicated, X-linked recessive)

SPG18 Gene

spastic paraplegia 18 (autosomal dominant)

SPG19 Gene

spastic paraplegia 19 (autosomal dominant)

SPG14 Gene

spastic paraplegia 14 (autosomal recessive)

SPOAN Gene

spastic paraplegia, optic atrophy, and neuropathy

SPG34 Gene

spastic paraplegia 34 (autosomal dominant)

SPG37 Gene

spastic paraplegia 37 (autosomal dominant)

SPG38 Gene

spastic paraplegia 38 (autosomal dominant, Silver syndrome)

SPG3B Gene

spastic paraplegia 3B

SPG32 Gene

spastic paraplegia 32 (autosomal recessive)

SPG29 Gene

spastic paraplegia 29 (autosomal dominant)

SPG5B Gene

spastic paraplegia 5B (autosomal recessive)
