The protein has 3 repeats of about 100 amino acids and each repeat has 2 predicted transmembrane alpha-helices separated by a hydrophilic segment. Northern blot analysis detected a 4.2-kb mRNA transcript in liver and pancreas, with little expression in all other tissues.

(1999)</a> identified apparent homozygosity for a 538G-A transition in the SLC25A15 gene, resulting in a glu180-to-lys (E180K) substitution in the predicted fourth transmembrane domain. The patient's Irish American father was an E180K heterozygote, but his Japanese mother was not. These observations, together with the different origins of the 2 parents, indicated that the patient represented a genetic compound for E180K and a second mutant ORNT1 allele that failed to amplify. Further studies suggested that the second allele in this patient carried a microdeletion involving ORNT1 inherited from the mother. The mutant E180K transporter targeted to the mitochondria, but was inactive, indicating that this substitution impairs activity without affecting targeting or stability. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=10369256" 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>

The mutation was not found in 116 control individuals. Overexpression studies showed that the mutant protein targeted normally to the mitochondrial and retained some residual activity. However, basal ornithine transport of primary untransfected patient fibroblasts showed loss of function; the observations were important, since they showed a discordance between the clinical and cellular phenotype in patients with HHH syndrome. The patients showed phenotypic variability, with 1 patient in particular having neurologic involvement, including poor school performance, low IQ (55), dysarthria, hyperreflexia, and cortical atrophy on MRI. This patient died from complications of hyperammonemic encephalopathy. The other patients had mild learning disabilities but no neurologic deficits.

<strong>Description</strong>

<span class="mim-text-font">
<p>The SLC25A15 gene encodes the mitochondrial ornithine transporter, which transports ornithine across the inner mitochondrial membrane from the cytosol to the mitochondrial matrix. This is a vital step in the urea cycle, which serves to eliminate toxic ammonium ions from the breakdown of nitrogen (summary by Camacho et al., 1999). </p>

<strong>Cloning and Expression</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>The fungi Neurospora crassa Arg13 and Saccharomyces cerevisiae Arg11 genes encode mitochondrial carrier family proteins that transport ornithine across the mitochondrial inner membrane. Camacho et al. (1999) used these sequences to identify a human expressed sequence tag (EST) corresponding to the orthologous human transporter. The SLC25A15 gene, which they termed ORNT1, encodes a 301-residue protein with 95% identity to mouse Ornt1 and 28% identity to Neurospora Arg13. The protein has 3 repeats of about 100 amino acids and each repeat has 2 predicted transmembrane alpha-helices separated by a hydrophilic segment. Northern blot analysis detected a 4.2-kb mRNA transcript in liver and pancreas, with little expression in all other tissues. In mice, the expressed protein localized to liver mitochondria and varied with changes in dietary protein. </p>

<p>Among 11 patients with the hyperornithinemia-hyperammonemia-homocitrullinuria syndrome (HHH syndrome; 238970), Camacho et al. (1999) identified 2 mutations in the ORNT1 gene (see, e.g., phe188del; 603861.0001 and E180K; 603861.0002), and a larger deletion. The phe188del accounted for 19 of 20 possible mutant ORNT1 alleles among French Canadian patients, consistent with a founder effect in that population. Expression of either murine or human ORNT1 restored normal ornithine metabolism in patient-derived fibroblasts. </p><p>Tsujino et al. (2000) reported 3 novel mutations in the SLC25A15 gene in Japanese patients with the HHH syndrome. </p><p>Miyamoto et al. (2001) reported 2 unrelated Japanese patients who were both homozygous for a nonsense mutation in the SLC25A15 gene (R179X; 603861.0003). </p><p>In 8 Italian patients with HHH syndrome, Salvi et al. (2001) identified 9 different mutations in the SLC25A15 gene, 7 of which were novel (see, e.g., 603861.0004). </p><p>Debray et al. (2008) noted that 22 different mutations of the SLC25A15 gene had been described in 49 patients from 31 unrelated families with HHH syndrome to date. </p><p>In 16 patients from 13 unrelated families with HHH syndrome, Tessa et al.

In vitro functional expression assays showed mutant proteins with decreased transport activity between 4 and 19% of control values. There were no apparent genotype/phenotype correlations. </p>

<p>In 9 of 10 French Canadian patients with the hyperornithinemia-hyperammonemia-homocitrullinuria syndrome (HHH syndrome; 238970), Camacho et al. (1999) identified a homozygous 3-bp in-frame deletion in the SLC25A15 gene, resulting in the deletion of phe188 from a sequence of 4 consecutive TTC phenylalanine codons (bp 553-564). in the predicted fourth transmembrane domain. The deletion resulted in an unstable protein. The tenth patient was compound heterozygous for this deletion and a second undetermined allele that has an undetectable transcript. In vitro functional expression studies showed that the F188del mutation resulted in loss of transporter function. The F188del mutant transporter did not target the mitochondria and was not detected in the cytosol, suggesting that this 1-codon deletion impairs stability and/or targeting of the transporter. </p>

<p>In a non-French Canadian patient with HHH (238970), Camacho et al. (1999) identified apparent homozygosity for a 538G-A transition in the SLC25A15 gene, resulting in a glu180-to-lys (E180K) substitution in the predicted fourth transmembrane domain. The patient's Irish American father was an E180K heterozygote, but his Japanese mother was not. These observations, together with the different origins of the 2 parents, indicated that the patient represented a genetic compound for E180K and a second mutant ORNT1 allele that failed to amplify. Further studies suggested that the second allele in this patient carried a microdeletion involving ORNT1 inherited from the mother. The mutant E180K transporter targeted to the mitochondria, but was inactive, indicating that this substitution impairs activity without affecting targeting or stability. </p>

<p>In 5 affected members of 2 related families of Mexican descent with HHH syndrome (238970), Camacho et al. (2006) identified a homozygous C-to-G transversion in exon 3 of the SLC25A15 gene, resulting in a thr32-to-arg (T32R) substitution in a conserved residue in the first hydrophilic loop facing the mitochondrial matrix. The mutation was not found in 116 control individuals. Overexpression studies showed that the mutant protein targeted normally to the mitochondrial and retained some residual activity. However, basal ornithine transport of primary untransfected patient fibroblasts showed loss of function; the observations were important, since they showed a discordance between the clinical and cellular phenotype in patients with HHH syndrome. The patients showed phenotypic variability, with 1 patient in particular having neurologic involvement, including poor school performance, low IQ (55), dysarthria, hyperreflexia, and cortical atrophy on MRI. This patient died from complications of hyperammonemic encephalopathy. The other patients had mild learning disabilities but no neurologic deficits. Two patients with the mildest defects were found to be carriers for a gain of function val181-to-gly (V181G) polymorphism in the ORNT2 gene (SLC25A2; 608157), whereas the members of the family who had the patient with the more severe phenotype had the wildtype val181 ORNT2 variant. The mitochondrial haplotypes of the 2 families also differed. Camacho et al. (2006) suggested that the genotype of HHH patients cannot predict the clinical course of the disease, and that other modifying factors, such as gene redundancy or mitochondrial background may further influence the phenotype. </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.
