Heterozygosity for the mutation was found in 15 of 41 healthy Alaskan Husky control dogs, but not in another 187 dogs of different breeds.

These mutations were not present among 192 ethnically matched controls. In vitro functional cellular expression studies showed that most of the K44E-mutant protein was impaired in intracellular transport while remaining normal in the endoplasmic reticulum. The E320Q mutant was identical in cell surface localization to wildtype protein but showed significantly decreased intracellular thiamine uptake activity. Onset of symptoms was in the second decade of life. Both patients also had severe partial complex seizures that were responsive to high-dose thiamine. Magnetic resonance imaging (MRI) of the brain showed high-intensity signals in the bilateral medial thalamus and periaqueductal region, which were characteristic of findings in Wernicke encephalopathy (<a href="/entry/277730">277730</a>), but there was no history of chronic alcohol use. These changes became normal within 1 month after treatment. Subacute ophthalmoplegia with nystagmus and ataxia occurred repeatedly within several months after the discontinuation of 100 mg of thiamine per day. There were no extrapyramidal features. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=19387023" 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>

(2013)</a> identified a homozygous c.20C-A transversion in the SLC19A3 gene, resulting in a ser7-to-ter (S7X) substitution. The mutation in the first family was found by a combination of homozygosity mapping and whole-exome sequencing, confirmed by Sanger sequencing, and filtered against the dbSNP (build 132) and 1000 Genomes Project databases. The mutation, which segregated with the disorder in the family, was not present in 460 control alleles. The mutations in the other 2 Moroccan families were found by direct sequencing of the SLC19A3 gene in 17 patients with Leigh syndrome. Haplotype analysis indicated a founder effect estimated to have occurred 1,250 to 1,750 years ago. The families all came from the Al Hoceima region in northern Morocco; 2 of the families were consanguineous. In vitro functional expression studies showed that the S7X mutant protein had no thiamine transporter activity, consistent with a complete loss of function. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=23423671" 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>

<span class="mim-text-font">
<p>By EST database searching with the RFC1 (SLC19A1; 600424) protein sequence as query, PCR, and screening of a human placenta cDNA library, Eudy et al. (2000) cloned a full-length SLC19A3 cDNA encoding a 496-amino acid protein. They also cloned the mouse homolog from a kidney cDNA library. Human SLC19A3 shares 39%, 48%, and 68% amino acid sequence identity with human SLC19A1 and SLC19A2 (603941) and mouse Slc19a3, respectively. Northern blot analysis of human tissues detected 3 transcripts of approximately 3.5, 2.6, and 2.0 kb in placenta, kidney, and liver. Highest expression was observed in placenta, with all 3 transcripts exhibiting similar levels of expression. In the liver and kidney, the 3.5-kb transcript was the most abundant. PCR analysis detected SLC19A3 transcripts in almost all tissues tested. Northern blot analysis in mouse tissues detected a single transcript in brain, kidney, lung, small intestine, heart, and testis, with the highest abundance in kidney and brain. PCR analysis identified weak expression of the mouse gene beginning at embryonic day 8.5 which peaked at E19 just prior to parturition. </p><p>Kono et al. (2009) found high SLC19A3 expression in human thalamus compared to other brain regions. </p><p>Subramanya et al. (2011) found expression of both the Slc19a2 and Slc19a3 genes in rat pancreatic acinar cells, with Slc19a2 showing higher expression. </p>

<span class="mim-text-font">
<p>By assaying transfected HeLa cells, Rajgopal et al. (2001) found that human SLC19A3 mediated transport of radiolabeled thiamine, but not folic acid, pyridoxine, niacin, methotrexate, or other organic cations examined. The pH optimum for thiamine transport was pH 7.4. </p><p>In cellular studies, Subramanian et al. (2006) demonstrated that SLC19A3 is a thiamine transporter expressed at the apical surface of polarized cells, but it does not function as a biotin transporter. SLC19A3 was also expressed in human glioma cells. </p>

<p>Biotin-thiamine-responsive basal ganglia disease (BTBGD; 607483), also known as thiamine metabolism dysfunction syndrome-2 (THMD2) or thiamine-responsive encephalopathy, is an autosomal recessive disorder with childhood onset that presents as a subacute encephalopathy and progresses to severe cogwheel rigidity, dystonia, quadriparesis, and eventually death if left untreated. Zeng et al. (2005) stated that all patients diagnosed to that time were of Saudi, Syrian, or Yemeni ancestry, and all had consanguineous parents. Using linkage analysis in 4 families, they mapped the genetic defect to 2q36.3 to a minimum candidate region of approximately 2 Mb on the basis of complete homozygosity. In this segment, each family displayed 1 of 2 different missense mutations that altered the coding sequence of SLC19A3 (606152.0001 and 606152.0002). The mutations were on different haplotypes. </p><p>In a Portuguese brother and sister with BTBGD, Debs et al. (2010) identified compound heterozygosity for 2 truncating mutations in the SLC19A3 gene (606152.0005-606152.0006), confirming that the disorder results from loss of function of this transporter. Each unaffected parent was heterozygous for 1 of the mutations. One of the patients only showed a therapeutic response to thiamine. </p><p>Kono et al. (2009) reported 2 Japanese brothers with onset of encephalopathy in the second decade of life. Genetic analysis identified compound heterozygous mutations in the SLC19A3 gene (606152.0003-606152.0004) in both brothers. Kono et al. (2009) stated that the phenotype differed from biotin-responsive basal ganglia disease because brain lesions were found in the thalamus and periaqueductal regions, not in the basal ganglia. </p><p>In affected patients from 3 families from the Al Hoceima province in northern Morocco with BTBGD manifest as severe infantile-onset fatal encephalopathy and Leigh syndrome (see 256000) on brain imaging, Gerards et al. (2013) identified the same homozygous truncating mutation in the SLC19A3 gene (S7X; 606152.0007). Haplotype analysis indicated a founder effect estimated to have occurred 1,250 to 1,750 years ago. The mutation in the first family was found by a combination of homozygosity mapping and whole-exome sequencing; the mutations in the subsequent families were found by direct sequencing of the SLC19A3 gene in 17 patients with Leigh syndrome. </p>

<span class="mim-text-font">
<p>Reidling et al. (2010) found that Slc19a3-null mice had reduced uptake of intestinal thiamine and decreased serum thiamine compared to wildtype mice. However, intestinal uptake of thiamine in Slc19a2-null mice was not significantly different from that of wildtype mice. Moreover, the level of expression of Slc19a2 was not altered in the intestine of Slc19a3-null mice, but the level of expression of Slc19a3 was upregulated in the intestine of Slc19a2-null mice, thus compensating for the defect. The findings suggested that Slc19a3 is required for normal uptake of thiamine in the intestine, and can fulfill normal levels of uptake in conditions associated with Slc19a2 dysfunction. </p><p>Subramanya et al. (2011) found expression of both the Slc19a2 and Slc19a3 genes in rat pancreatic acinar cells. Chronic alcohol feeding of rats resulted in significant inhibition of carrier-mediated thiamine uptake by pancreatic acinar cells, and was associated with a significant reduction in expression of Slc19a2 and Slc19a3 at the protein and mRNA levels. The results demonstrated that thiamine uptake by pancreatic acinar cells occurs through a carrier-mediated process, and that thiamine transporters are expressed in these cells. </p><p>Alaskan Husky encephalopathy (AHE), a fatal brain disease in young Alaskan Husky dogs, presents as a multifocal central nervous system deficit with seizures, altered mentation, dysphagia, central blindness, hypermetria, proprioceptive positioning deficits, ataxia, and tetraparesis. Brain imaging shows abnormal intracranial lesions consistent with Leigh syndrome in humans. Vernau et al. (2013) determined that AHE is caused by homozygosity for a 4-bp deletion and a single nucleotide change (c.624insTTGC, c.625C-A) in the Slc19a3.1 gene that is predicted to result in a protein truncation. Heterozygosity for the mutation was found in 15 of 41 healthy Alaskan Husky control dogs, but not in another 187 dogs of different breeds. Canines have 2 paralogs of SLC19A3, Slc19a3.1 and Slc19a3.2, resulting from gene duplication. Slc19a3.1 is primarily expressed in the cerebrum, cerebellum, spinal cord, kidney, and testes, whereas Slc19a3.2 is mainly expressed in the kidney and liver, suggesting tissue-specific expression of these paralogs. </p><p>Vernau et al. (2015) found that the cerebral cortex and thalamus of 2 dogs with AHE were severely deficient in thiamine pyrophosphate (TPP)-dependent enzymes compared to controls. These decreases in enzymatic activity were accompanied by decreases in mitochondrial mass, mtDNA copy number, and oxidative phosphorylation, although the latter decreases did not meet the threshold for a mitochondrial respiratory chain disorder. Affected brain tissue also showed evidence of increased oxidative stress. The findings indicated that the phenotype results from a brain-specific thiamine deficiency, leading to brain mitochondrial dysfunction and increased oxidative stress. </p>

<p>In 2 Japanese brothers with biotin-thiamine-responsive basal ganglia disease (BTBGD; 607483) characterized by diplopia, seizures, and white matter changes in the thalamus without serum thiamine deficiency, Kono et al. (2009) identified compound heterozygosity for 2 mutations in the SLC19A3 gene: a 218A-G transition in exon 2, resulting in a lys44-to-glu (K44E) substitution, and a 1047G-C transversion in exon 3, resulting in a glu320-to-gln (E320Q; 606152.0004) substitution. These mutations were not present among 192 ethnically matched controls. In vitro functional cellular expression studies showed that most of the K44E-mutant protein was impaired in intracellular transport while remaining normal in the endoplasmic reticulum. The E320Q mutant was identical in cell surface localization to wildtype protein but showed significantly decreased intracellular thiamine uptake activity. Onset of symptoms was in the second decade of life. Both patients also had severe partial complex seizures that were responsive to high-dose thiamine. Magnetic resonance imaging (MRI) of the brain showed high-intensity signals in the bilateral medial thalamus and periaqueductal region, which were characteristic of findings in Wernicke encephalopathy (277730), but there was no history of chronic alcohol use. These changes became normal within 1 month after treatment. Subacute ophthalmoplegia with nystagmus and ataxia occurred repeatedly within several months after the discontinuation of 100 mg of thiamine per day. There were no extrapyramidal features. </p>

<p>In 9 patients from 3 unrelated Moroccan families with biotin-thiamine-responsive basal ganglia disease (BTBGD; 607483), presenting as Leigh syndrome, Gerards et al. (2013) identified a homozygous c.20C-A transversion in the SLC19A3 gene, resulting in a ser7-to-ter (S7X) substitution. The mutation in the first family was found by a combination of homozygosity mapping and whole-exome sequencing, confirmed by Sanger sequencing, and filtered against the dbSNP (build 132) and 1000 Genomes Project databases. The mutation, which segregated with the disorder in the family, was not present in 460 control alleles. The mutations in the other 2 Moroccan families were found by direct sequencing of the SLC19A3 gene in 17 patients with Leigh syndrome. Haplotype analysis indicated a founder effect estimated to have occurred 1,250 to 1,750 years ago. The families all came from the Al Hoceima region in northern Morocco; 2 of the families were consanguineous. In vitro functional expression studies showed that the S7X mutant protein had no thiamine transporter activity, consistent with a complete loss of function. </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.
