The mutations, which were found by whole-exome sequencing and confirmed by Sanger sequencing, occurred de novo in 2 unrelated patients and segregated with an autosomal dominant pattern of inheritance in the 3 remaining families. Functional studies of the variants and studies of patient cells were not performed, but all were predicted to result in a loss of ATP2B2 function and haploinsufficiency. Genetic analysis showed that most of the patients also carried heterozygous variants of uncertain significance in the CDH23 gene (<a href="/entry/605516">605516</a>) or in other genes that may have modified the phenotype, although the authors excluded a major effect of these variants and concluded that the ATP2B2 mutations are the underlying cause of monogenic deafness in these families.

An A-to-G nucleotide transition in dfw DNA caused a glycine-to-serine substitution at a highly conserved amino acid position, whereas a second mutant allele carried a 2-bp deletion that caused a frameshift predicted to result in a truncated protein. In the cochlea, the Atp2b2 protein was localized to stereocilia and the basolateral wall of hair cells in wildtype mice, but was not detected in deafwaddler mice. The findings indicated that mutation of Atp2b2 may cause deafness and imbalance by affecting sensory transduction in stereocilia as well as neurotransmitter release from the basolateral membrane. These mutations affecting Atp2b2 were the first to be found in a mammalian plasma membrane calcium pump and defined a new class of deafness genes that directly affect hair-cell physiology. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=9697703" 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>PMCA2 exhibits a highly restricted tissue distribution, suggesting that it serves more specialized physiologic functions than some of the other PMCA isoforms.

Analysis of auditory-evoked brainstem responses showed that homozygous mutants were deaf and that heterozygous mice had a significant hearing loss.

Onset of hearing loss occurred between ages 2 and 6 years. The mutation, which was found by whole-exome sequencing and confirmed by Sanger sequencing, segregated with the disorder in the family. Genetic analysis indicated that 2 affected family members also carried a heterozygous predicted splice site variant in the CDH23 gene (<a href="/entry/605516">605516</a>) that may have had a modifying effect on the phenotype; however, this CDH23 variant was inherited from an unaffected mother. Functional studies of the variant and studies of patient cells were not performed, but the ATP2B2 variant was predicted to result in a loss of function and haploinsufficiency. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=30535804" 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 class="mim-text-font">
<p>Brandt et al. (1992) isolated and characterized a cDNA for the human PMCA2 gene from a human fetal brain cDNA library. The 1,190-amino acid protein showed greater than 98% sequence identity to the rat protein. </p><p>By PCR, Brandt et al. (1992) detected PMCA2 expression in brain, liver, spinal cord, and adrenal gland. There were 2 PCR products in spinal cord, suggesting the presence of PMCA2 splice variants. </p><p>By RT-PCR, Santiago-Garcia et al. (1996) found variable expression of the PMCA and SERCA (see 108730) genes during development of human fetal heart. PMCA2 was not detected in placenta or in fetal heart at the 3 stages tested, but 3 splice variants of PMCA2 were detected in adult atrium. </p><p>Street et al. (1998) noted that the ATP2B2 gene undergoes alternative splicing. All 4 ATP2B proteins are predicted to have 10 transmembrane-spanning domains with approximately 80% of the protein mass located in the cytoplasm. The intracellular loop between T2 and T3 encodes the transducing domain that couples ATP hydrolysis with calcium translocation. The largest intracellular loop, between T4 and T5, includes the phosphoenzyme-forming residue and the nucleotide-binding domain. The intracellular C terminus contains the calmodulin-binding, protein kinase C, cAMP-dependent kinase and acidic phospholipid regulatory domains. </p>

<strong>Gene Function</strong>

<span class="mim-text-font">
<p>Elwess et al. (1997) found that the alternative splice variants PMCA2a and PMCA2b had much higher affinity for calmodulin than the corresponding forms of PMCA4. At a high calmodulin concentration, PMCA2b showed higher calcium affinity. The calcium affinity was localized to the C terminus. Elwess et al. (1997) concluded that the PMCA2 variants maintain a low free cytosolic calcium concentration. </p><p>Street et al. (1998) found Atp2b2 expression in mouse auditory and vestibular hair cells, suggesting that the channel provides the means to remove calcium from stereocilia. </p><p>By yeast 2-hybrid analysis of a human brain cDNA expression library, DeMarco et al. (2002) found that PCMA2b interacted with NHERF2 (SLC9A3R2; 606553). Coimmunoprecipitation analysis indicated that the interaction was specific and selective, in that PCMA4b did not interact with either NHERF2 or NHERF1 (SLC9A3R1; 604990), and PCMA2b preferred NHERF2 over NHERF1. Fluorescence-tagged PCMA2b was expressed at the apical membrane of canine kidney epithelial cells, where it colocalized with apically targeted NHERF2. DeMarco et al. (2002) hypothesized that the PCMA2b-NHERF2 interaction may allow the assembly of PMCA2b in a multiprotein Ca(2+) signaling complex. </p><p>Chicka and Strehler (2003) found that PMCA2b localized to both the apical and basolateral membranes of polarized epithelial cells. Different splice variants of the protein showed differential membrane targeting. </p>

<p>Using the PMCA2 cDNA to probe Southern blots of human-rodent somatic cell hybrid DNAs, Brandt et al. (1992) mapped the PMCA2 gene to human chromosome 3. By a combination of fluorescence in situ hybridization, analysis of somatic cell hybrids, and genetic linkage analysis in CEPH families, Wang et al. (1994) confirmed assignment of the ATP2B2 gene to 3p26-p25. </p><p>Richards et al. (1993) reported that the PMCA2 gene, which is located on 3p, is situated centromeric to the gene (VHL; 608537) for von Hippel-Lindau disease (193300). They reported other results that excluded PMCA2 as the site of the mutation in VHL. </p>

<p>In 11 patients from 5 unrelated families with autosomal dominant deafness-82 (DFNA82; 619804), Smits et al. (2019) identified heterozygous nonsense, splice site, or frameshift mutations in the ATP2B2 gene (see, e.g., 108733.0002-108733.0005). The mutations, which were found by whole-exome sequencing and confirmed by Sanger sequencing, occurred de novo in 2 unrelated patients and segregated with an autosomal dominant pattern of inheritance in the 3 remaining families. Functional studies of the variants and studies of patient cells were not performed, but all were predicted to result in a loss of ATP2B2 function and haploinsufficiency. Genetic analysis showed that most of the patients also carried heterozygous variants of uncertain significance in the CDH23 gene (605516) or in other genes that may have modified the phenotype, although the authors excluded a major effect of these variants and concluded that the ATP2B2 mutations are the underlying cause of monogenic deafness in these families. The ATP2B2 mutations affected the ortholog of the rat Atp2b2 w/a isoform, which is expressed in inner and outer hair cells; mice with mutations in the Atp2b2 gene have progressive deafness (see ANIMAL MODEL). Smits et al. (2019) concluded that loss of ATP2B2 function in the ear may result in calcium cytotoxicity leading to degeneration of inner and outer hair cells and progressive hearing loss. </p>

<strong>Animal Model</strong>

</div>
<span class="mim-text-font">
<p>Street et al. (1998) demonstrated that the deafwaddler (dfw) mouse mutant, which is deaf and displays vestibular/motor imbalance, has a mutation in the Atp2b2 gene. An A-to-G nucleotide transition in dfw DNA caused a glycine-to-serine substitution at a highly conserved amino acid position, whereas a second mutant allele carried a 2-bp deletion that caused a frameshift predicted to result in a truncated protein. In the cochlea, the Atp2b2 protein was localized to stereocilia and the basolateral wall of hair cells in wildtype mice, but was not detected in deafwaddler mice. The findings indicated that mutation of Atp2b2 may cause deafness and imbalance by affecting sensory transduction in stereocilia as well as neurotransmitter release from the basolateral membrane. These mutations affecting Atp2b2 were the first to be found in a mammalian plasma membrane calcium pump and defined a new class of deafness genes that directly affect hair-cell physiology. </p><p>PMCA2 exhibits a highly restricted tissue distribution, suggesting that it serves more specialized physiologic functions than some of the other PMCA isoforms. A unique role in hearing is suggested by the high levels of PMCA2 expression in cochlear outer hair cells and spiral ganglion cells. To analyze the physiologic role of PMCA2, Kozel et al. (1998) produced PMCA2-deficient mice by gene targeting. Homozygous PMCA2-null mice grew more slowly than heterozygous and wildtype mice and exhibited an unsteady gait and difficulties in maintaining balance. Histologic analysis of the cerebellum and inner ear of mutant and wildtype mice showed that null mutants have slightly increased numbers of Purkinje neurons (in which PMCA2 is highly expressed), a decreased thickness of the molecular layer, an absence of otoconia in the vestibular system, and a range of abnormalities of the organ of Corti. Analysis of auditory-evoked brainstem responses showed that homozygous mutants were deaf and that heterozygous mice had a significant hearing loss. These data demonstrated that PMCA2 is required for both balance and hearing and suggested that it may be a major source of the calcium used in the formation and maintenance of otoconia. </p><p>Reinhardt et al. (2004) noted that the PMCA2bw isoform is expressed approximately 100-fold during lactation, and that expression levels correlate with milk production and calcium secretion. They found that mice homozygous for the loss of Pmca2 produced milk with 60% less calcium than that of heterozygous or wildtype mice. There was no alteration in whole-body calcium metabolism in the null mice. The findings indicated that the Pmca2bw isoform, which allows the enzyme to function as a high affinity calcium extrusion system on the apical membrane, is necessary to produce the high levels of calcium in milk, and that it occurs by direct secretion by the calcium pump. </p><p>Bortolozzi et al. (2010) characterized Tommy (tmy) mutant mice, which were generated in an N-ethyl-N-nitrosourea mutagenesis screen. Tmy/tmy mice were profoundly deaf at birth and were smaller than their littermates. They developed severe ataxia, with hesitant wobbly gait and frequent hyperextension of the rear limbs. Tmy heterozygous mice developed deafness by 12 weeks of age, with full penetrance by 30 weeks. Bortolozzi et al. (2010) identified the tmy mutation as a nonconservative G-to-A transition in exon 7 of the Atp2b2 gene, resulting in a gln629-to-lys (E629K) substitution in Atp2b2 w/a, the Atp2b2 isoform expressed in hair cells (the substitution corresponds to E584K in the Atp2b2 z/b isoform, which lacks the 45-amino acid insertion in Atp2b2 w/a). Expression of mutant Atp2b2 in Chinese hamster ovary cells caused impaired calcium extrusion, with inhibition of long-term, nonstimulated calcium export. Recordings of neonate organotypic cultures of utricle sensory epithelium confirmed impaired calcium export in both tmy/tmy and tmy/+ mice following rapid calcium release. Immunofluorescence analysis of the organ of Corti in tmy/tmy mice showed a progressive base to apex degeneration of hair cells after postnatal day 40. </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.
