The same technique revealed a different homozygous mutation in the TRAPPC11 gene (Ala372_Ser429del; <a href="#0002">614138.0002</a>) in affected members of 2 Hutterite families with a slightly different phenotype. The G980R mutation occurred in the gryzun domain, whereas the deletion occurred in the foie gras domain. The Syrian patients had childhood onset of progressive proximal muscle weakness resulting in impaired ambulation. The shoulder girdle muscles were less severely affected than the hip girdle muscles. Other features included hip dysplasia, scoliosis, and increased serum creatine kinase. Affected individuals from the Hutterite families had early-onset psychomotor delay and evidence of a hyperkinetic movement disorder characterized mainly by choreiform movements of the trunk, limbs, and head, although athetoid movements, tremor, and dystonic posturing were also noted. All had truncal ataxia resulting in gait instability, mild muscle weakness, and increased serum creatine kinase. Patient cells from both groups showed increased fragmentation of the Golgi apparatus and decreased amounts of the mutant proteins. Studies in yeast suggested that the mutant missense protein lost the ability to interact properly with other TRAPP proteins. Patient cells also showed altered protein transport along the secretory pathway, with a delayed exit from the Golgi and a defect in the formation and/or movement of late endosomes/lysosomes. The findings suggested that altered membrane trafficking is the underlying molecular mechanism of this disease spectrum. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=23830518" 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>In an 8-year-old Han Chinese girl with a variant of LGMD2S (LGMDR18), <a href="#6" class="mim-tip-reference" title="Liang, W.-C., Zhu, W., Mitsuhashi, S., Noguchi, S., Sacher, M., Ogawa, M., Shih, H.-H., Jong, Y.-J., Nishino, I. &lt;strong&gt;Congenital muscular dystrophy with fatty liver and infantile-onset cataract caused by TRAPPC11 mutations: broadening of the phenotype.&lt;/strong&gt; Skeletal Muscle 5: 29, 2015.

The mutation was found by a combination of autozygosity mapping and whole-exome sequencing and was confirmed by Sanger sequencing. It segregated with the disorder in both families and was not found in the dbSNP, 1000 Genomes Project, or ExAC databases. Haplotype analysis suggested a founder effect. Analysis of patient cells showed that the mutation resulted in an aberrant out-of-frame transcript (Val588Glyfs16Ter) with only about 20% of the normal transcript compared to controls, and Western blot analysis showed a dramatic decrease in levels of the full-length protein. Patient cells showed hypoglycosylation of LAMP1 (<a href="/entry/153330">153330</a>). In vitro studies of patient fibroblasts showed that delayed exit through the Golgi apparatus of a marker protein, indicating a defect in secretory trafficking. In addition to muscular dystrophy, the patients had global developmental delay, intellectual disability with poor speech, alacrima, and achalasia. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=27707803" 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>Gene Function</strong>

<span class="mim-text-font">
<p>Scrivens et al. (2011) found that depletion of TRAPPC11 in HeLa cells via interfering RNA resulted in partial disassembly of the TRAPP complex. There was also Golgi fragmentation into dispersed punctae and arrested anterograde trafficking, suggesting that TRAPPC11 is involved in an early trafficking event between the endoplasmic reticulum (ER) and Golgi. </p><p>Using small interfering RNA in HeLa cells, DeRossi et al. (2016) found that knockdown of TRAPPC11, but not other TRAPP subunits, resulted in accumulation of nonglycosylated TRAP-alpha (SSR1; 600868). </p>

<p>By whole-exome sequencing combined with linkage analysis of a Syrian family with limb-girdle muscular dystrophy-18 (LGMDR18; 615356), previously designated LGMD2S, Bogershausen et al. (2013) identified a homozygous mutation in the TRAPPC11 gene (G980R; 614138.0001). The same technique revealed a different homozygous mutation in the TRAPPC11 gene (Ala372_Ser429del; 614138.0002) in affected members of 2 Hutterite families with a slightly different phenotype. The G980R mutation occurred in the gryzun domain, whereas the deletion occurred in the foie gras domain. The Syrian patients had childhood onset of progressive proximal muscle weakness resulting in impaired ambulation. The shoulder girdle muscles were less severely affected than the hip girdle muscles. Other features included hip dysplasia, scoliosis, and increased serum creatine kinase. Affected individuals from the Hutterite families had early-onset psychomotor delay and evidence of a hyperkinetic movement disorder characterized mainly by choreiform movements of the trunk, limbs, and head, although athetoid movements, tremor, and dystonic posturing were also noted. All had truncal ataxia resulting in gait instability, mild muscle weakness, and increased serum creatine kinase. Patient cells from both groups showed increased fragmentation of the Golgi apparatus and decreased amounts of the mutant proteins. Studies in yeast suggested that the mutant missense protein lost the ability to interact properly with other TRAPP proteins. Patient cells also showed altered protein transport along the secretory pathway, with a delayed exit from the Golgi and a defect in the formation and/or movement of late endosomes/lysosomes. The findings suggested that altered membrane trafficking is the underlying molecular mechanism of this disease spectrum. </p><p>In an 8-year-old Han Chinese girl with a variant of LGMD2S (LGMDR18), Liang et al. (2015) identified compound heterozygous mutations in the TRAPPC11 gene (614138.0001 and 614138.0003). The mutations, which were found by targeted next-generation sequencing and confirmed by Sanger sequencing, segregated with the disorder in the family. In addition to muscular dystrophy, the patient had delayed psychomotor development with borderline cognitive function, infantile-onset cataracts, and hepatic steatosis. Liang et al. (2015) noted that the 'foie gras' (foigr) mutant zebrafish shows lipid accumulation in hepatocytes (see ANIMAL MODEL). </p><p>In 4 patients from 2 unrelated consanguineous Turkish families with a variant of LGMD2S (LGMDR18), Koehler et al. (2017) identified a homozygous splice site mutation in the TRAPPC11 gene (614138.0004). The mutation was found by a combination of autozygosity mapping and whole-exome sequencing and was confirmed by Sanger sequencing. It segregated with the disorder in both families. Haplotype analysis suggested a founder effect. </p><p>In a patient with LGMDR18, Corona-Rivera et al. (2024) identified compound heterozygous mutations in the TRAPPC11 gene (Y251H, 614138.0005; A353G, 614138.0006). Analysis of patient fibroblasts demonstrated a slight disruption of Golgi morphology. In patient fibroblasts, expression of ICAM1 (147840) and LAMP2 (309060) were decreased, and expression of LAMP1 (153330) was increased, compared to controls. </p>

<strong>Animal Model</strong>

</div>
<span class="mim-text-font">
<p>DeRossi et al. (2016) stated that 'foie gras' (foigr) mutant zebrafish exhibit lipid accumulation in hepatocytes and have a viral DNA insertion in the trappc11 gene that results in a C-terminally truncated protein. They found that trappc11 mutant larvae also had a defect in motility. Using Western blot analysis, DeRossi et al. (2016) detected mutant trappc11 at an apparent molecular mass of 56 kD and wildtype trappc11 at 129 kD. Foigr hepatocytes had a significant defect in synthesis of lipid-linked oligosaccharides, blocking protein N-glycosylation and causing protein misfolding, with chronic activation of the unfolded protein response (UPR) in ER. The block in N-glycosylation caused compensatory upregulation of nearly all genes involved in N-glycosylation and chronically stressed UPR-activated genes involved in sterol metabolism. Trappc11 mutant hepatocytes also developed abnormal ER morphology, fragmentation of the Golgi complex, and retention of secretory cargo. DeRossi et al. (2016) proposed that TRAPPC11 may function as a scaffold for enzymes of protein N-glycosylation or as a cofactor for an enzyme in lipid-linked oligosaccharide synthesis. </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.
