Human SPG11 shares 85% identity with the homologous protein in dog, 76% with mouse, and 73% with rat. The spatacsin protein includes 4 putative transmembrane domains, suggesting that the protein may be a receptor or transporter, as well as a leucine zipper and coiled-coil domain. It was assigned to the aromatic compound dioxygenase superfamily because of 22% identity with the consensus sequence between residues 2104 and 2381. The SPG11 gene is expressed ubiquitously in the nervous system but most prominently in the cerebellum, cerebral cortex, hippocampus, and pineal gland. Overexpression of a GFP fusion protein in COS-7 cells demonstrated a diffuse and reticular cytosolic and perinuclear distribution, sometimes also present in nuclei. At least 3 alternative transcripts were detected in all structures of adult brain. mRNA in situ hybridization in rat brain detected no expression in newborn rat, but found expression throughout the brain in adult rat. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=17322883" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p><p><a href="#10" class="mim-tip-reference" title="Perez-Branguli, F., Mishra, H.

Knockdown of Spg11 in mouse cortical neurons resulted in a reduction of neurite length and complexity associated with a decrease in acetylated stabilized tubulin. Studies in mouse brain showed that Spg11 colocalized with the vesicle marker VAMP2 (<a href="/entry/185881">185881</a>) and the presynaptic marker SNAP25 (<a href="/entry/600322">600322</a>), consistent with a role in synaptic vesicles. Knockdown of Spg11 in mouse neurons causes a decrease in synaptic vesicles in neurites and disrupted anterograde axonal transport. SPG11 patient-derived neurons showed similar defects in anterograde axonal transport as well as large numbers of inclusions, membrane-encircled structures, and vacuoles within neurites, suggesting alterations in the transport of membranous organelles.

Both patients were wheelchair-bound due to lower limb spasticity, had amyotrophy of the hands, sphincter disturbances, thin corpus callosum, and late-onset progressive central retinal degeneration. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=19194956" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p>

<strong>Cloning and Expression</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>By sequencing clones obtained from a size-fractionated fetal brain cDNA library, Nagase et al. (2001) cloned KIAA1840. The deduced protein contains 1,437 amino acids. RT-PCR ELISA detected moderate expression in all tissues and specific brain regions examined, with highest expression in liver, followed by brain and ovary. </p><p>Stevanin et al. (2007) demonstrated that the full-length 8-kb SPG11 transcript encodes a predicted protein of 2,443 amino acids, which they termed spatacsin, after 'spasticity with thin or atrophied corpus callosum syndrome protein.' Human SPG11 shares 85% identity with the homologous protein in dog, 76% with mouse, and 73% with rat. The spatacsin protein includes 4 putative transmembrane domains, suggesting that the protein may be a receptor or transporter, as well as a leucine zipper and coiled-coil domain. It was assigned to the aromatic compound dioxygenase superfamily because of 22% identity with the consensus sequence between residues 2104 and 2381. The SPG11 gene is expressed ubiquitously in the nervous system but most prominently in the cerebellum, cerebral cortex, hippocampus, and pineal gland. Overexpression of a GFP fusion protein in COS-7 cells demonstrated a diffuse and reticular cytosolic and perinuclear distribution, sometimes also present in nuclei. At least 3 alternative transcripts were detected in all structures of adult brain. mRNA in situ hybridization in rat brain detected no expression in newborn rat, but found expression throughout the brain in adult rat. </p><p>Perez-Branguli et al. (2014) found expression of the SPG11 gene in human and mouse cortical projection neurons throughout embryonic development and in the adult brain. Spg11 was expressed in axonal and dendritic processes as well as in a punctate cytosolic pattern in mouse cortical neurons and human neurons. </p>

<p>By immunoprecipitation analysis of HeLa cells, Slabicki et al.

Knockdown of KIAA0415, C20ORF29, or SPG15 in HeLa cells reduced homologous recombination in a test substrate, whereas knockdown of SPG11 or DKFZp761E198 had no effect. </p>

<p><strong><em>Spastic Paraplegia 11, Autosomal Recessive</em></strong></p><p>
In 11 families with autosomal recessive hereditary spastic paraplegia with thin corpus callosum (SPG11; 604360), Stevanin et al. (2007) found 10 different mutations in the spatacsin gene (see, e.g., 610844.0001-610844.0004; 610844.0011-610844.0013). The mutations were either nonsense or insertions or deletions leading to a frameshift, suggesting a loss-of-function mechanism. </p><p>Del Bo et al. (2007) identified a homozygous mutation in the SPG11 gene (733delAT; 610844.0004) in 27-year-old Italian opposite-sex dizygotic twins with autosomal recessive SPG11. </p><p>In 9 unrelated families with SPG11, Hehr et al. (2007) identified 11 different mutations, including 10 novel mutations, in the SPG11 gene (see, e.g., 610844.0005-610844.0006) in the homozygous or compound heterozygous state. Four of the families were consanguineous, including 3 Turkish families initially reported by Olmez et al. (2006). Mutations were distributed throughout the entire spatacsin gene without obvious clustering. </p><p>Bauer et al. (2009) used high-resolution comparative genomic hybridization (HRCGH) to identify deletions in the SPG11 gene in 3 patients with SPG11 in whom only 1 mutant SPG11 allele had been identified by gene sequencing. HRCGH analysis suggested heterozygous genomic deletion in all 3 patients; however, quantitative PCR confirmed an 8.23-kb deletion in only 1 patient. The 8.23-kb deletion resulted in loss of exons 31 to 34 and was also found in the proband's affected sister and their unaffected father. The clinical features in the brother and sister did not differ from those of patients with point mutations. </p><p>Perez-Branguli et al. (2014) found that neuronal cultures derived from pluripotent stem cells of 2 SPG11 patients showed profound reductions in the neuritic complexity and severely impaired axonal process outgrowth compared to controls. Knockdown of Spg11 in mouse cortical neurons resulted in a reduction of neurite length and complexity associated with a decrease in acetylated stabilized tubulin. Studies in mouse brain showed that Spg11 colocalized with the vesicle marker VAMP2 (185881) and the presynaptic marker SNAP25 (600322), consistent with a role in synaptic vesicles. Knockdown of Spg11 in mouse neurons causes a decrease in synaptic vesicles in neurites and disrupted anterograde axonal transport. SPG11 patient-derived neurons showed similar defects in anterograde axonal transport as well as large numbers of inclusions, membrane-encircled structures, and vacuoles within neurites, suggesting alterations in the transport of membranous organelles. The findings suggested that axonal dysfunction underlies the disorder. </p><p><strong><em>Juvenile Amyotrophic Lateral Sclerosis 5</em></strong></p><p>
In affected members of 10 unrelated families with a protracted course of autosomal recessive juvenile-onset amyotrophic lateral sclerosis-5 (ALS5; 602099), Orlacchio et al. (2010) identified homozygous or compound heterozygous mutations in the SPG11 gene (see, e.g., 610844.0003-610844.0004, 610844.0010-610844.0013). All of the families were consanguineous and of different ethnic backgrounds, including Italian, Japanese, Turkish, Brazilian, and Canadian. Most of the mutations resulted in a truncated protein, and all but 1 of the 12 different mutations identified had previously been reported in patients with spastic paraplegia-11. However, the patients reported by Orlacchio et al. (2010) had a slightly different phenotype, namely the absence of cognitive impairment, thin corpus callosum, and ocular abnormalities. In addition, most ALS5 patients had bulbar symptoms. Postmortem examination of 1 patient showed typical pathologic features of ALS, including small pyramids, loss of anterior horn large motor neurons and loss of large myelinated fibers in the anterolateral columns. Remaining neurons showed central chromatolysis, pigmentary degeneration, and round hyaline inclusions; Bunina bodies were not observed. Functional studies of the variants and studies of patient cells were not performed. The 10 families with ALS5 were ascertained from a cohort of 25 families who underwent SPG11 gene sequencing, thus accounting for 40% of families. Orlacchio et al. (2010) did not speculate on why the same mutations led to a slightly different phenotype more consistent with ALS than SPG, but noted that the common finding of axonal involvement in both ALS and SPG suggested a common pathologic pathway in both disorders. The findings expanded the phenotype associated with SPG11 gene mutations to included autosomal recessive juvenile ALS with long-term survival. </p><p><strong><em>Charcot-Marie-Tooth Disease Type 2X</em></strong></p><p>
In affected members of 12 unrelated families with autosomal recessive axonal Charcot-Marie-Tooth disease type 2X (CMT2X; 616668), Montecchiani et al. (2016) identified 15 different biallelic mutations in the SPG11 gene (see, e.g., 610844.0001-610844.0003; 610844.0014-610844.0015). Thirteen mutations had previously been reported as causative of SPG11 or ALS5; 2 mutations were novel. Montecchiani et al. (2016) noted that identical mutations can cause different phenotypes, indicating that genotype/phenotype correlations for SPG11 mutations are often unpredictable. All mutations except 1 were predicted to result in a truncated protein with loss of function; functional studies of the variants were not performed. The mutations, which were found by a combination of linkage analysis and candidate gene sequencing, segregated with the disorder in the families. The families showed different ethnic origins, including Italy, Brazil, Canada, England, Iran, and Japan. </p>

To ensure long-term funding for the OMIM project, we have diversified
our revenue stream. We are determined to keep this website freely
accessible. Unfortunately, it is not free to produce. Expert curators
review the literature and organize it to facilitate your work. Over 90%
of the OMIM's operating expenses go to salary support for MD and PhD
science writers and biocurators. Please join your colleagues by making a
donation now and again in the future. Donations are an important
component of our efforts to ensure long-term funding to provide you the
information that you need at your fingertips.
