However, the phenotype of this patient was similar to that of the other patients, suggesting that cerebral deposition of Mn in this disorder arises secondarily from an increased systemic load of Mn rather than a primary defect of Mn clearance in the brain. <a href="#19" class="mim-tip-reference" title="Tuschl, K., Meyer, E., Valdivia, L.

The mutation, which was found by exome sequencing and confirmed by Sanger sequencing, segregated fully with disease in the family and was not found in 100 ethnically matched controls or in the dbSNP, 1000 Genomes Project, or ExAC databases. Functional analysis in HEK293 cells demonstrated that unlike wildtype ZIP14, the L441R mutant did not localize to the plasma membrane, and there were no signs of zinc uptake in cells transfected with L441R. Overexpression of the L441R mutant resulted in a significant increase in intracellular zinc accumulation, greater than that for wildtype ZIP14, indicating that labile zinc was trapped in the mutant cells. Analysis of patient skull and first cervical vertebra biopsy specimens compared to control skull biopsy showed severe involvement of the patient internal cortex, which was wider than that of the control and characterized by a great and dense amount of well-organized bone, suggesting increased bone formation or decreased bone resorption. The number of Haversian channels and number of osteocytes were significantly lower in the patient internal cortex compared to patient external cortex and cervical vertebra cortex or control internal cortex. <a href="https://pubmed.ncbi.nlm.nih.gov/?term=2300107+29621230" 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>The SLC39A14 gene encodes a divalent metal transporter that transports zinc, manganese, iron, and cadmium (summary by Tuschl et al., 2016). Zinc is an essential cofactor for hundreds of enzymes. It is involved in protein, nucleic acid, carbohydrate, and lipid metabolism, as well as in the control of gene transcription, growth, development, and differentiation (summary by Taylor and Nicholson, 2003). </p>

<strong>Cloning and Expression</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>By sequencing clones obtained from a size-fractionated immature myeloid cell line cDNA library, Nomura et al. (1994) cloned SLC39A14, which they designated KIAA0062. The deduced 531-amino acid protein contains possible transmembrane domains. Northern blot analysis detected SLC39A14 expression in all tissues and cell lines examined. Highest expression was in liver, and lowest expression was in spleen, thymus, and peripheral blood leukocytes. </p><p>By searching databases for sequences similar to a unique motif within LIV-1 (SLC39A6; 608731), Taylor and Nicholson (2003) identified SLC39A14, which they designated LZT-Hs4. SLC39A14 contains a long N terminus, followed by 8 putative transmembrane domains and a short C terminus. It also has a motif similar to the catalytic zinc-binding site of matrix metalloproteases. Expression of SLC39A14 in Chinese hamster ovary cells showed an apparent molecular mass of 53 kD and suggested SLC39A14 has up to 3 N-linked carbohydrate side chains. Under nonreducing conditions, SLC39A14 migrated as a trimer, consistent with the formation of an ion channel. SLC39A14 was expressed on the plasma membrane, colocalized with F-actin, and concentrated on lamellipodiae in a manner similar to membrane-type matrix metalloproteases. </p><p>Using Western blot analysis, Taylor et al. (2005) detected epitope-tagged human ZIP14 as a doublet with an apparent molecular mass of 60 kD, similar to the predicted size of 54 kD. ZIP14 also formed apparent trimers and higher molecular mass species that increased in nonreducing conditions. Immunofluorescence microscopy detected ZIP14 at CHO cell membranes, with particularly dense staining in regions of cell-cell contact. </p><p>Using transfected HepG2 cells, Zhao et al. (2010) found that epitope-tagged human ZIP14 localized to the plasma membrane and partially colocalized with internalized transferrin (TF; 190000) in endosomes, as well as with other endosomal and lysosomal markers. </p><p>The SLC39A1 gene encodes 3 isoforms: isoforms 1 and 2 differ by 20 amino acids encoded by an alternatively spliced exon 4 (4B and 4A, respectively). Isoform 3 has an alternative exon 9, but shares the remaining protein sequence with isoform 1. Tuschl et al. (2016) found expression of the SLC39A1 gene in cell membranes and cytoplasm of human hepatocytes in a punctate pattern. In human brain, SLC39A1 was found in large neurons, especially in the globus pallidus, insular cortex, and dentate nucleus as well at lower levels in some other brain regions. Isoform 1 was ubiquitously expressed, whereas isoform 2 was not expressed in the brain, heart, skeletal muscle, or skin. Both isoforms 1 and 2 facilitated Mn uptake in HEK293 cells, but isoform 2 showed a greater ability to do so. Mn resulted in an increase only in transcription of zebrafish slc39a14 isoform 2. (In the article by Tuschl et al. (2016), there is a discrepancy in the isoforms encoded by exons 4A and 4B; Tuschl (2016) confirmed that isoform 1 is encoded by exon 4B and isoform 2 is encoded by exon 4A.) </p><p>Hendrickx et al. (2018) performed immunohistochemistry on sections of giant cell tumor and osteoblastoma tissue, and detected expression of ZIP14 in the osteoclast-like giant cells and osteoblasts of osteoblastoma tissue. However, ZIP14 was not expressed in osteocytes from those tissues. Quantitative RT-PCR in mouse mesenchymal stem cells showed that expression of Zip14 was stable during proliferation and maturation of osteoblast differentiation, and rose during the mineralization phase. In addition, there was 2-fold greater expression of Zip14 in osteoclasts of mouse calvaria compared to long bones. </p>

<strong>Gene Function</strong>

<span class="mim-text-font">
<p>Liuzzi et al. (2005) found that Zip14 was the most upregulated zinc transporter in response to turpentine-induced inflammation or lipopolysaccharide (LPS) in mouse liver. Il6 (147620) -/- mice exhibited neither hypozincemia nor Zip14 induction with turpentine-induced inflammation, and the hypozincemic response was milder in Il6 -/- mice exposed to LPS than in wildtype mice. Northern blot analysis revealed liver-specific upregulation of a single Zip14 transcript. Immunohistochemical analysis showed increased expression of Zip14 on the plasma membrane of hepatocytes in response to both LPS and turpentine. Il6 also produced increased expression of Zip14 in primary hepatocyte cultures and localization of the Zip14 protein to the plasma membrane. Transfection of mouse Zip14 cDNA into human embryonic kidney cells increased zinc uptake. Liuzzi et al. (2005) concluded that ZIP14 is a zinc importer upregulated by IL6 that plays a major role in the hypozincemia accompanying the acute-phase response to inflammation and infection. </p><p>Taylor et al. (2005) found that transfected CHO cells expressing human ZIP14 exhibited elevated intracellular zinc concentration in response to increased extracellular zinc concentration. Zinc transport required all transmembrane domains of ZIP14, and no transport was evident when experiments were repeated at 4 degrees C. </p><p>Liuzzi et al. (2006) analyzed the capability of mouse Zip14 to mediate uptake of non-TF-bound iron following expression in human and insect cells. Zip14 localized to the plasma membrane, and its overexpression increased uptake of both radiolabeled zinc and iron. Iron was taken up as Fe(2+), and uptake was inhibited by zinc. Suppression of endogenous Zip14 in mouse hepatocytes by small interfering RNA (siRNA) reduced uptake of both iron and zinc. Zip14 siRNA also decreased metallothionein (see 156350) mRNA levels, suggesting that compensatory mechanisms were not sufficient to restore intracellular zinc. </p><p>Gao et al. (2008) found that knockdown of ZIP14 in human HepG2 hepatoma cells abolished the inhibitory effect of HFE (613609) on uptake of non-TF-bound iron. Expression of ZIP14 in HeLa cells significantly increased uptake of non-TF-bound iron. HFE appeared to reduce the stability of ZIP14 protein and had no effect on ZIP14 mRNA. </p><p>Zhao et al. (2010) found that expression of mouse Zip14 in HEK293T cells increased uptake of radiolabeled Fe at pH 7.5 and 6.5, but not at pH 5.5. Knockdown of ZIP14 in HepG2 cells reduced assimilation of Fe from Fe-TF. </p><p>Steimle et al. (2019) demonstrated that ZIP8 (608732) and ZIP14 were both localized to the apical and basolateral membranes in brain microvascular capillary endothelial cells (BMVECs), with ZIP14 as the predominant transporter at the basal surface. The cells accumulated manganese from both the abluminal and luminal faces in polarized BMVEC cultures, and siRNA studies indicated that both transporters had a role in the basal and apical transport of manganese. However, as ZIP14 was the predominant transporter at the basal surface, knockdown of ZIP14 had a more robust effect on basal rather than apical manganese uptake. Steimle et al. (2019) concluded that ZIP14 has a role in manganese secretory flow out of the brain, whereas ZIP8 has a role in both manganese uptake and brain accumulation as well as secretory flow of manganese out of the brain. </p><p>Scheiber et al. (2019) established polarized cultures of wildtype and ZIP14 knockout CaCo-2 cells. In wildtype CaCo-2 cells, immunoblotting for ZIP14 demonstrated enrichment of ZIP14 at the basolateral membrane. Manganese transport studies in the polarized cells showed that ZIP14 knockout cells had severe impairment of basolateral to apical (or secretory) manganese transport and enhanced manganese transport in the apical to basolateral (absorptive) direction. Scheiber et al. (2019) concluded that these studies supported ZIP14 as the major transporter mediating basolateral manganese uptake in enterocytes. </p>

<p><strong><em>Hypermanganesemia with Dystonia 2</em></strong></p><p>
In 8 patients from 5 unrelated consanguineous families with hypermanganesemia with dystonia-2 (HMNDYT2; 617013), Tuschl et al. (2016) identified 5 different homozygous mutations in the SLC39A14 gene (608736.0001-608736.0005), including 2 truncating and 3 missense mutations. Transfection of the missense mutations into HEK293 cells showed that the mutant protein was expressed and localized normally, but resulted in decreased Mn uptake compared to wildtype, consistent with a loss of function. One of the patients had a mutation that affected only isoform 2, which is not expressed in the brain. However, the phenotype of this patient was similar to that of the other patients, suggesting that cerebral deposition of Mn in this disorder arises secondarily from an increased systemic load of Mn rather than a primary defect of Mn clearance in the brain. Tuschl et al. (2016) postulated that loss-of-function mutations in SLC39A14 lead to impaired hepatic Mn uptake with resultant hypermanganesemia and downstream neurotoxic effects. </p><p>By whole-exome sequencing in 2 unrelated children from the United Arab Emirates with HMDNY2, Rodan et al. (2018) identified homozygosity for the same intronic mutation in the SLC3A14 gene (608736.0007). The parents of 1 patient, who were consanguineous, were confirmed to be heterozygous for the mutation. </p><p>In a patient with HMNDYT2, Juneja et al. (2018) identified a homozygous mutation in the SLC39A14 gene (R128W; 608736.0008). The mutation, which was found by whole-exome sequencing and confirmed by Sanger sequencing, was present in heterozygous state in the parents. Functional studies were not performed. </p><p>In an Arab Libyan patient, born to consanguineous parents, with HMNDYT2, Zeglam et al. (2019) identified a homozygous missense mutation in the SLC39A14 gene (P379L; 608736.0009). The mutation was found by whole-exome sequencing. Functional studies were not performed. </p><p>In a 65-year-old Ashkenazi Jewish woman, born to consanguineous parents, with HMNDYT2, Namnah et al. (2020) identified a homozygous missense mutation in the SLC39A14 gene (G356S; 608736.0010). The mutation was identified by whole-exome sequencing. Functional studies were not performed. The patient had a clinical history of long-term dysarthria and dystonia and an elevated blood manganese level. </p><p><strong><em>Hyperostosis Cranialis Interna</em></strong></p><p>
In affected members of a Dutch pedigree with hyperostosis cranialis interna (HCIN; 144755), Hendrickx et al. (2018) identified heterozygosity for a missense mutation (L441R; 608736.0006) in the SLC39A14 gene that segregated fully with disease in the family and was not found in 100 controls or in public variant databases. </p>

<p>By injecting ferric citrate to saturate Tf and increase plasma non-Tf-bound iron, Jenkitkasemwong et al. (2015) found that liver and pancreas of Slc39a14 -/- mice were resistant to iron overload compared with wildtype. In contrast, iron uptake in other Slc39a14 -/- tissues was higher than wildtype. Loss of Slc39a14 also countered iron accumulation in liver following dietary iron overload. Loss of Slc39a14 prevented hepatic iron overload in the Hfe -/- and Hfe2 (HJV; 608374) -/- mouse models of hemochromatosis (see 235200). However, loss of Slc39a14 did not prevent iron accumulation in other tissues and cells of Hfe -/- or Hfe2 -/- mice, but instead resulted in altered patterns of iron accumulation compared with single-knockout or wildtype mice. Jenkitkasemwong et al. (2015) concluded that SLC39A14 is required for development of hepatic iron overload in hereditary hemochromatosis. </p><p>Troche et al. (2016) found that acute inflammation following injection of lipopolysaccharide (LPS) in mice induced expression of Zip14, which correlated with upregulated expression of cytokines. Knockout of Zip14 in mice caused changes in white adipose tissue, including increased cytokine production, increased plasma leptin (LEP; 164160), hypertrophied adipocytes, altered lipid homeostasis, elevated total cellular zinc content, and dampened insulin signaling. Adipose tissue from Zip14 -/- mice had increased levels of preadipocyte markers, lower expression of a differentiation marker, and activation of the NF-kappa-B (see 164011) and Stat3 (102582) pathways. These changes were accompanied by systemic endotoxemia. Metabolic changes in adipose were reversed following administration of oral antibiotics. Knockdown of Zip14 via siRNA in 3T3-L1 mouse adipocytes resulted in impaired ability to mobilize zinc, which caused dysregulation of inflammatory pathways following LPS stimulation. Troche et al. (2016) hypothesized that deletion of Zip14 may limit the availability of intracellular zinc, yielding the phenotype of inflammation with hypertrophy. </p><p>Tuschl et al. (2016) found that knockdown of the slc39a14 gene in zebrafish resulted in increased Mn levels, but unchanged Fe, Zn, and Cd levels. The mutant animals survived into adulthood without any obvious morphologic or developmental defects. However, exposure to Mn resulted in decreased locomotor activity and increased sensitivity to Mn-induced toxicity compared to wildtype. Mn accumulated predominantly in the brain of mutant animals, but not in the viscera. Treatment of mutant larvae with a chelator resulted in decreased levels of Mn uptake. </p><p>Hendrickx et al. (2018) analyzed calvaria of Zip14 +/+ and Zip14 -/- mice and found no significant differences in calvarial thickness or porosity. The authors generated mice with ubiquitous expression of the L441R mutation (see 608736.0001) and observed perinatal lethality. Conditional expression of L441R in osteoblasts showed no significant differences in calvarial parameters; however, analysis of the femora showed a marked increase in cortical thickness due to enhanced endosteal bone formation. In addition, there was an osteoporotic trabecular bone phenotype. The authors concluded that ZIP14 is a regulator of bone homeostasis. </p><p>Jenkitkasemwong et al. (2018) showed that Slc39a14 knockout mice (Slc39a14 -/-) had an abnormal tissue distribution of manganese, including low levels of manganese in the liver and elevated manganese levels in the bone and brain, particularly in the pons, globus pallidus, and cerebellum. The livers of the Slc39a14 -/- mice at 4 weeks of age also had low iron, zinc, and cobalt compared to wildtype mice. Manganese tracer studies in the Slc39a14 -/- mice demonstrated impaired uptake by the liver and pancreas, and reduced excretion from the intestine. The Slc39a14 -/- mice had locomotor abnormalities. A low manganese diet in the Slc39a14 -/- mice resulted in normal brain manganese levels but not in correction of motor defects. </p><p>Scheiber et al. (2019) generated liver-specific and intestinal-specific Zip14 knockout mice. The liver-specific knockout mice had reduced manganese in the liver and did not have accumulation of manganese in other tissues. The intestinal-specific Zip14 knockout mice had increased hepatic and brain manganese levels. Scheiber et al. (2019) concluded that intestinal ZIP14 is important for the control of systemic manganese homeostasis. </p>

<p>In a 1-year-old patient with hypermanganesemia with dystonia-2 (HMNDYT2; 617013), Juneja et al. (2018) identified a homozygous c.382C-T transition (c.382C-T, NM_015359) in the SLC39A14 gene, resulting in an arg128-to-trp (R128W) substitution. The mutation, which was identified by whole-exome sequencing and confirmed by Sanger sequencing, was present in heterozygous state in the parents. The mutation was not present in the ExAC database. Functional studies were not performed. The patient had a history of neurodegeneration with dystonia, elevated blood manganese levels, and abnormal MRI signal in the globus pallidus and dentate nucleus. </p>
