Abstract
Grover disease is an acquired dermatologic disorder characterized by pruritic vesicular and eroded skin lesions. While its pathologic features are well-defined, including impaired cohesion of epidermal keratinocytes, the etiology of Grover disease remains unclear and it lacks any FDA-approved therapy. Interestingly, drug-induced Grover disease occurs in patients treated with B-RAF inhibitors that can paradoxically activate C-RAF and the downstream kinase MEK. We recently identified hyperactivation of MEK and ERK as key drivers of Darier disease, which is histologically identical to Grover disease, supporting our hypothesis that they share a pathogenic mechanism. To model drug-induced Grover disease, we treated human keratinocytes with clinically utilized B-RAF inhibitors dabrafenib or vemurafenib and leveraged a fluorescent biosensor to confirm they activated ERK, which disrupted intercellular junctions and compromised keratinocyte sheet integrity. Consistent with clinical data showing concomitant MEK blockade prevents Grover disease in patients receiving B-RAF inhibitors, we found that MEK inhibition suppressed excess ERK activity to rescue cohesion of B-RAF-inhibited keratinocytes. Validating these results, we demonstrated ERK hyperactivation in skin biopsies of vemurafenib-induced Grover disease, but also in spontaneous Grover disease. In sum, our data define a pathogenic role for ERK hyperactivation in Grover disease and support MEK inhibition as a therapeutic strategy. GRAPHICAL ABSTRACT

Abstract
Importance Darier disease (DD) is a rare genetic skin disorder caused by heterozygous variants in the ATP2A2 gene. Clinical manifestations include recurrent hyperkeratotic papules and plaques that occur mainly in seborrheic areas. Although some of the lesions wax and wane in response to environmental factors, others are severe and respond poorly to therapy. Objective To investigate the molecular mechanism underlying the persistency of skin lesions in DD. Design, Setting, and Participants In this case series, DNA was extracted from unaffected skin, transient and persistent lesional skin, and blood from 9 patients with DD. Genetic analysis was used using paired-whole exome sequencing of affected skin and blood or by deep sequencing of ATP2A2 of affected skin. Chromosomal microarray analysis was used to reveal copy number variants and loss of heterozygosity. All variants were validated by Sanger sequencing or restriction fragment length polymorphism. Interventions or Exposures Paired whole-exome sequencing and deep sequencing of ATP2A2 gene from blood and skin samples isolated from persistent, transient lesions and unaffected skin in patients with DD. Main Outcomes and Measures Germline and somatic genomic characteristics of persistent and transient cutaneous lesions in DD. Results Of 9 patients with DD, all had heterozygous pathogenic germline variants in the ATP2A2 gene, 6 were female. Participant age ranged from 40 to 69 years on enrollment. All 11 persistent skin lesions were associated with second-hit somatic variants in the ATP2A2 gene. The somatic variants were classified as highly deleterious via combined annotation-dependent depletion (CADD) scores or affect splicing, and 3 of them had been previously described in patients with DD and acrokeratosis verruciformis of Hopf. Second-hit variants in the ATP2A2 gene were not identified in the transient lesions (n = 2) or the normal skin (n = 2). Conclusions and Relevance In this study, persistent DD lesions were associated with the presence of second-hit somatic variants in the ATP2A2 gene. Identification of these second-hit variants offers valuable insight into the underlying mechanisms that contribute to the lasting nature of persistent DD lesions.

Abstract
Mutation of the ATP2A2 gene encoding sarco-endoplasmic reticulum calcium ATPase 2 (SERCA2) was linked to Darier disease more than 2 decades ago; however, there remain no targeted therapies for this disorder causing recurrent skin blistering and infections. Since Atp2a2-knockout mice do not phenocopy its pathology, we established a human tissue model of Darier disease to elucidate its pathogenesis and identify potential therapies. Leveraging CRISPR/Cas9, we generated human keratinocytes lacking SERCA2, which replicated features of Darier disease, including weakened intercellular adhesion and defective differentiation in organotypic epidermis. To identify pathogenic drivers downstream of SERCA2 depletion, we performed RNA sequencing and proteomics analysis. SERCA2-deficient keratinocytes lacked desmosomal and cytoskeletal proteins required for epidermal integrity and exhibited excess MAPK signaling, which modulates keratinocyte adhesion and differentiation. Immunostaining patient biopsies substantiated these findings, with lesions showing keratin deficiency, cadherin mislocalization, and ERK hyperphosphorylation. Dampening ERK activity with MEK inhibitors rescued adhesive protein expression and restored keratinocyte sheet integrity despite SERCA2 depletion or chemical inhibition. In sum, coupling multiomic analysis with human organotypic epidermis as a preclinical model, we found that SERCA2 haploinsufficiency disrupts critical adhesive components in keratinocytes via ERK signaling and identified MEK inhibition as a treatment strategy for Darier disease.

Abstract
Darier's follicular dyskeratosis (synonym: Dariers disease, DarierWhites disease) is a rare genetic disease with an autosomal dominant type of inheritance, which belongs to the group of acantholytic dermatoses and is characterized by a violation of keratinization processes with lesions of the skin, nails, mucous membranes of the oral cavity and genitals. Dariers disease is caused by a mutation in the ATP2A2 gene. This disrupts the operation of the SERCA2 pump and leads to a violation of calcium homeostasis in keratinocytes and a decrease in intercellular adhesion. Dariers disease is manifested by brownish papules in seborrheic and intertriginal areas with a keratotic surface, which can merge into macerated plaques. Typical nail changes in Dariers disease include red and white longitudinal stripes ending in V-shaped notches on the free edge of the nail plates. Warty acrokeratosis, as well as bullous, hemorrhagic, comedonic and linear-segmental types are clinical variants of Dariers disease. Dariers disease is often associated with neuropsychiatric disorders. Exacerbation may be caused by superinfection with Staphylococcus aureus or by herpes simplex virus. Histology in Darieres disease is characterized by pronounced dyskeratosis. For local therapy, keratolytic agents are important, as well as antiseptic treatment to avoid superinfection. In addition, local corticosteroids are used. Among the systemic methods of treatment, the systemic retinoids are the most effective. Ablative methods of treatment (dermabrasion, CO2 laser, Er:YAG laser) are effective in limited areas.

Abstract
Darier (Darier-White) disease (DD) is an autosomal dominant skin disorder caused by pathogenic mutations in the ATP2A2 gene which encodes a calcium ATPase in the sarco-endoplasmic reticulum (SERCA2). Defects in the SERCA2 protein leads to an impairment of cellular calcium homeostasis, which in turn, triggers cell death pathways. There is a high prevalence of neuropsychiatric disorders in patients affected by this condition, namely intellectual disability, bipolar disorder, schizophrenia, and suicidality. Though these associations have been well-documented over the years, little has been discussed or investigated regarding the pathophysiological mechanisms. The goal of this article is to review the literature related to the most commonly associated neuropsychiatric disorders found in patients with DD, highlight the pathophysiological mechanisms underlying each condition, and examine potential interventions that may be of interest for future development. A literature search was performed using PubMed to access and review relevant articles published in the last 40 years. Keywords searched included Darier disease neuropsychiatric, Darier disease pathophysiology, SERCA2 central nervous system, SERCA 2 skin, ATP2A2 central nervous system, ATP2A2 skin, sphingosine-1-phosphate signaling skin, sphingosine-1-phosphate signaling central nervous system, P2X7 receptor skin, and P2X7 receptor central nervous system. Our search resulted in 2,692 articles, of which 61 articles were ultimately included in this review.

Abstract
The autosomal-dominant genodermatoses Darier disease and Hailey-Hailey disease present special challenges to dermatologists. Despite their similar pathogenesis featuring impaired adhesion of suprabasal keratinocytes as a result of defective ATPases in epidermal calcium channels, the two diseases differ considerably in clinical presentation and therapeutic options. Darier disease is characterized by reddish brown, keratotic papules in seborrheic and intertriginous areas, which may coalesce into extensive lesions. Individuals affected with Hailey-Hailey disease primarily develop intertriginous papulovesicles and small blisters, which often evolve into erythematous plaques with erosions and painful fissures. Quality of life is significantly reduced because of complaints (itch, burning sensation, pain), body malodor and chronicity. Therapeutic options remain limited. Antiseptics and intermittent topical corticosteroids are a cornerstone of therapy, and systemic anti-infective treatment is often required in cases of superinfection. Ablative surgical interventions such as dermabrasion and CO2 laser surgery can lead to long-term remissions in intertriginous Hailey-Hailey disease, while temporary relief may also be achieved by intralesional injections of botulinum toxin. Of the systemic medications available for Darier disease, acitretin, which is approved for this purpose, has the best supporting evidence. The efficacy of immunosuppressants and immune modulators is inconsistent. Low-dose naltrexone produces more satisfactory results in Hailey-Hailey than Darier disease. The present CME article summarizes current knowledge of the two dermatoses, taking recent developments into account.

Abstract
Calcium (Ca2+) is a fundamental regulator of cell fate and intracellular Ca2+ homeostasis is crucial for proper function of the nerve cells. Given the complexity of neurons, a constellation of mechanisms finely tunes the intracellular Ca2+ signaling. We are focusing on the sarco/endoplasmic reticulum (SR/ER) calcium (Ca2+)-ATPase (SERCA) pump, an integral ER protein. SERCA's well established role is to preserve low cytosolic Ca2+ levels ([Ca2+]cyt), by pumping free Ca2+ ions into the ER lumen, utilizing ATP hydrolysis. The SERCA pumps are encoded by three distinct genes, SERCA1-3, resulting in 12 known protein isoforms, with tissue-dependent expression patterns. Despite the well-established structure and function of the SERCA pumps, their role in the central nervous system is not clear yet. Interestingly, SERCA-mediated Ca2+ dyshomeostasis has been associated with neuropathological conditions, such as bipolar disorder, schizophrenia, Parkinson's disease and Alzheimer's disease. We summarize here current evidence suggesting a role for SERCA in the neurobiology of neuropsychiatric and neurodegenerative disorders, thus highlighting the importance of this pump in brain physiology and pathophysiology.

Abstract
Darier disease (DD) is an autosomal dominant skin disorder caused by mutations in ATP2A2 encoding the sarco/endoplasmic reticulum Ca2+ ATPase Isoform 2 (SERCA2). Evidence of a population-level association between DD and psychiatric disorders suggests that mutations in ATP2A2 may have pleiotropic effects on the brain as well as skin. Evidence of genotype-phenotype relationships between ATP2A2 mutations and neuropsychiatric phenotypes would further support this suggestion. We investigated genotype-phenotype correlations between lifetime neuropsychiatric features and ATP2A2 mutation type (dichotomized into likely gene disrupting [LGD] or protein altering) in 75 unrelated individuals with DD. We also looked for evidence of clustering of mutations within SERCA2 according to neuropsychiatric features. Combining our data with the existing literature, the rate of LGD mutations was found to be significantly higher among DD cases/families with bipolar disorder, schizophrenia, or affective psychosis (p = .011). We also found a significant relationship between mutations located in the S4-M4 region of the protein and the presence of a severe neuropsychiatric phenotype (p = .032). Our findings add support to the hypothesis that Darier-causing mutations in ATP2A2 confer susceptibility to neuropsychiatric dysfunction, in particular severe psychiatric illness. This, together with evidence from research on common polymorphisms confirms ATP2A2 as a gene at which variation influences susceptibility to major psychiatric illness.

Abstract
Calcium (Ca2+) ions are prominent cell signaling regulators that carry information for a variety of cellular processes and are critical for neuronal survival and function. Furthermore, Ca2+ acts as a prominent second messenger that modulates divergent intracellular cascades in the nerve cells. Therefore, nerve cells have developed intricate Ca2+ signaling pathways to couple the Ca2+ signal to their biochemical machinery. Notably, intracellular Ca2+ homeostasis greatly relies on the rapid redistribution of Ca2+ ions into the diverse subcellular organelles which serve as Ca2+ stores, including the endoplasmic reticulum (ER). It is well established that Ca2+ released into the neuronal cytoplasm is pumped back into the ER by the sarco-/ER Ca2+ ATPase 2 (SERCA2), a P-type ion-motive ATPase that resides on the ER membrane. Even though the SERCA2 is constitutively expressed in nerve cells, its precise role in brain physiology and pathophysiology is not well-characterized. Intriguingly, SERCA2-dependent Ca2+ dysregulation has been implicated in several disorders that affect cognitive function, including Darier's disease, schizophrenia, Alzheimer's disease, and cerebral ischemia. The current review summarizes knowledge on the expression pattern of the different SERCA2 isoforms in the nervous system, and further discusses evidence of SERCA2 dysregulation in various neuropsychiatric disorders. To the best of our knowledge, this is the first literature review that specifically highlights the critical role of the SERCA2 in the brain. Advancing knowledge on the role of SERCA2 in maintaining neuronal Ca2+ homeostasis may ultimately lead to the development of safer and more effective pharmacotherapies to combat debilitating neuropsychiatric disorders.

Abstract
Darier disease is a rare and severe autosomal dominant skin disease characterised by malodorous keratotic papules in seborrheic areas of the skin. Darier disease affects up to 1 in 30 000 people and is caused by mutations in the ATP2A2 gene, which encodes to the sarco/endoplasmic reticulum calcium-ATPase isoform 2 that pumps calcium into the endoplasmic reticulum. Although many ATP2A2 variants have been described, it is not known if genotype correlates with phenotype, which could be important for prognosis and treatment. This is the first study to use whole exome sequencing to screen the ATP2A2 gene in a cohort of 28 clinically diagnosed Darier disease patients. Twenty-one different disease causing variants were identified and 15 of these were novel. Sixteen of the 21 variants were predicted to be pathogenic using in silico prediction programs. There were seven missense, four intronic/splice-sites, three frameshifts, two in-frame deletions, four nonsense and one synonymous mutations. This study also found ten patients who harbour more than one ATP2A2 variant. The phenotype of the patient cohort was assessed by photography and by patient questionnaires. The genotype-phenotype association was examined for all variants in relation to the patient's disease severity score, and no correlation could be established.

Abstract
Darier disease and Acrokeratosis Verruciformis of Hopf (AKV) are rare disorders of keratinization with autosomal dominant inheritance and very distinct clinical pictures. Both have been shown to be caused by mutations in ATP2A2 (ATPase, Ca++ transporting, cardiac muscle, slow-twitch) a gene encoding one of the SERCA (sarcoplasmic/endoplasmic reticulum calcium ATPase2) intracellular pumps with a crucial role in cell-to-cell adhesion in both skin and heart. While hundreds of different missense and nonsense mutations cause Darier disease, only one missense mutation, p.(Pro602Leu), has been identified in families with AKV. We report a family with AKV due to the p.(Pro602Leu) mutation and discuss implications for this recurrent mutation on knowledge of ATP2A2 structure and function.

Abstract
The two disorders of cornification associated with mutations in genes coding for intracellular calcium pumps are Darier disease (DD) and Hailey-Hailey disease (HHD). DD is caused by mutations in the ATP2A2 gene, whereas the ATP2C1 gene is associated with HHD. Both are inherited as autosomal-dominant traits. DD is mainly defined by warty papules in seborrheic and flexural areas, whereas the major symptoms of HHD are vesicles and erosions in flexural skin. Both phenotypes are highly variable. In 12%-40% of DD patients and 12%-55% of HHD patients, no mutations in ATP2A2 or ATP2C1 are found. We provide a comprehensive review of clinical variability in DD and HHD and a review of all reported mutations in ATP2A2 and ATP2C1. Having the entire spectrum of ATP2A2 and ATP2C1 variants allows us to address the question of a genotype-phenotype correlation, which has not been settled unequivocally in DD and HHD. We created a database for all mutations in ATP2A2 and ATP2C1 using the Leiden Open Variation Database (LOVD v3.0), for variants reported in the literature and future inclusions. This data may be of use as a reference tool in further research on treatment of DD and HHD.

Abstract
As a pathological condition, epilepsy is caused by abnormal neuronal discharge in brain which will temporarily disrupt the cerebral functions. Epilepsy is a chronic disease which occurs in all ages and would seriously affect patients' personal lives. Thus, it is highly required to develop effective medicines or instruments to treat the disease. Identifying epilepsy-related genes is essential in order to understand and treat the disease because the corresponding proteins encoded by the epilepsy-related genes are candidates of the potential drug targets. In this study, a pioneering computational workflow was proposed to predict novel epilepsy-related genes using the random walk with restart (RWR) algorithm. As reported in the literature RWR algorithm often produces a number of false positive genes, and in this study a permutation test and functional association tests were implemented to filter the genes identified by RWR algorithm, which greatly reduce the number of suspected genes and result in only thirty-three novel epilepsy genes. Finally, these novel genes were analyzed based upon some recently published literatures. Our findings implicate that all novel genes were closely related to epilepsy. It is believed that the proposed workflow can also be applied to identify genes related to other diseases and deepen our understanding of the mechanisms of these diseases.

Abstract
AIM Though genetic factors play a major role in the pathophysiology of psychoses including bipolar disorder (BD) and schizophrenia, lack of well-established causative genetic mutations hampers their neurobiological studies. Darier's disease, an autosomal dominant skin disorder caused by mutations of ATP2A2 on chromosome 12q23-24.1, encoding sarco/endoplasmic reticulum calcium transporting ATPase 2 (SERCA2), reportedly cosegregates with BD. A recent genome-wide association study showed an association of schizophrenia with ATP2A2. METHODS We sequenced all coding regions of ATP2A2 in a newly identified patient with Darier's disease and BD. In addition, we performed a literature survey to examine whether likely gene disrupting (LGD) mutations are related to psychoses. RESULTS We identified a rare heterozygous mutation, c.1288-6A>G, at the 3' end of intron 10 in the patient. A minigene splicing assay showed that this mutation introduces a new splice site causing a frameshift and premature stop codon. A literature survey of case reports of patients with Darier's disease and psychoses revealed that the rate of LGD mutations causing frameshift, altered splicing, gain of stop codon, or loss of start codon was significantly higher among the mutations harbored by these cases (9 of 11) than that of ATP2A2 mutations for which comorbidity of psychosis was not reported (107 of 237, P = 0.026). The only non-LGD mutation (p.C560R) reported in patients with Darier's disease and BD caused decreased ATP2A2 protein expression. CONCLUSION These results suggest that psychoses in Darier's disease may be caused by a pleiotropic effect of loss-of-function mutations of ATP2A2.

Abstract
Limb-girdle muscular dystrophy type 2A (LGMD2A) is a form of muscular dystrophy caused by
mutations in calpain 3 (CAPN3). Several studies have implicated Ca2+
dysregulation as an underlying event in several muscular dystrophies, including LGMD2A. In
this study we used mouse and human myotube cultures, and muscle biopsies in order to
determine whether dysfunction of sarco/endoplasmatic Ca2+-ATPase (SERCA) is
involved in the pathology of this disease. In CAPN3-deficient myotubes, we found decreased
levels of SERCA 1 and 2 proteins, while mRNA levels remained comparable with control
myotubes. Also, we found a significant reduction in SERCA function that resulted in
impairment of Ca2+ homeostasis, and elevated basal intracellular
[Ca2+] in human myotubes. Furthermore, small Ankyrin 1 (sAnk1), a
SERCA1-binding protein that is involved in sarcoplasmic reticulum integrity, was also
diminished in CAPN3-deficient fibres. Interestingly, SERCA2 protein was patently reduced
in muscles from LGMD2A patients, while it was normally expressed in other forms of
muscular dystrophy. Thus, analysis of SERCA2 expression may prove useful for diagnostic
purposes as a potential indicator of CAPN3 deficiency in muscle biopsies. Altogether, our
results indicate that CAPN3 deficiency leads to degradation of SERCA proteins and
Ca2+ dysregulation in the skeletal muscle. While further studies are needed
in order to elucidate the specific contribution of SERCA towards muscle degeneration in
LGMD2A, this study constitutes a reasonable foundation for the development of therapeutic
approaches targeting SERCA1, SERCA2 or sAnk1.

Abstract
BACKGROUND Darier disease is an autosomal dominant skin disorder caused by mutations in the ATP2A2 gene. Anecdotal reports suggest a relationship between Darier disease and intellectual disabilities, but these reports are based on small clinical samples and limited by absence of control populations. OBJECTIVES To examine the risk of intellectual disability and subclinical impairments in cognitive ability in Darier disease. METHODS We conducted a matched cohort study based on Swedish Population-, Patient- and Conscript Registers. The risk of being diagnosed with intellectual disability was estimated in 770 individuals with Darier disease, compared with matched comparison individuals without Darier disease. Associations were examined with risk ratios from conditional logistic regressions. In addition, we analysed test-based cognitive ability data (i.e. IQ data) from the Swedish conscript examination, for a subset of patients without diagnosed intellectual disability. RESULTS Individuals with Darier disease had a sixfold increased risk of being diagnosed with intellectual disability (risk ratio 6.2, 95% confidence interval 3.1-12.4). For conscripted individuals with Darier disease but no diagnosed intellectual disability, mean cognitive ability scores were about half a standard deviation lower than for comparison subjects. CONCLUSIONS Darier disease is associated with intellectual disability and subclinical impairments in cognitive ability. The Darier-causing mutations merit further attention in molecular genetic research on intellectual disability and cognitive ability.

Abstract
OBJECTIVES Darier disease is an autosomal dominant skin disorder caused by mutations in the ATPase, Ca++ transporting, cardiac muscle, slow twitch 2 (ATP2A2) gene and previously reported to cosegregate with bipolar disorder and schizophrenia in occasional pedigrees. It is, however, unknown whether these associations exist also in the general population, and the objective of this study was to examine this question. METHODS We compared a national sample of individuals with Darier disease and their first-degree relatives with matched unexposed individuals from the general population and their first-degree relatives, respectively. To examine risks for bipolar disorder and schizophrenia, risk ratios and 95% confidence intervals (CIs) were estimated using conditional logistic regressions. RESULTS Individuals with Darier disease had a 4.3 times higher risk of being diagnosed with bipolar disorder (95% CI: 2.6-7.3) and a 2.3 times higher risk of being diagnosed with schizophrenia (95% CI: 1.1-5.2) than matched individuals from the general population. Relatives of individuals with Darier disease had a 1.6 times higher risk of having bipolar disorder (95% CI: 1.1-2.5) than relatives of matched individuals from the general population, but no increased risk of schizophrenia (risk ratio = 0.8, 95% CI: 0.4-1.8). CONCLUSIONS The association between Darier disease and bipolar disorder is manifest also in the population, and our data suggest that genetic variability within the ATP2A2 gene that causes Darier disease also confers susceptibility for bipolar disorder. The Darier-causing mutations merit additional attention in molecular genetic research on bipolar disorder.

Abstract
Darier's disease is a skin disorder characterized by multiple eruptions of hyperkeratosis or crusted papules at seborrheic areas with histologic acantholysis and dyskeratosis. It is caused by mutations in a single gene, being ATP2A2 and that is expressed in the skin and brain. The cooccurrence of various neurologic and psychiatric diseases with Darier's disease has been reported frequently in literature. They include mood disorders, epilepsy, encephalopathy, and schizophrenia. In this study, we report a pediatric case with the cooccurrence of Darier's disease and epilepsy. We also revised current English literature on this topic.

Abstract
Follicular disorders are possibly a commonly seen, though rarely reported, group of disorders, which are localized around follicles and appendages and clinically present as small papules. Classically, clinicopathological follicular plugging is seen in the "true" follicular disorders, which are appropriately referred to as follicular keratosis. Another subtype is folliculitis (infectious or noninfectious) and the follicular mimickers that clinically resemble "true" follicular disorders without the follicular keratoses. Acne vulgaris has an amalgamation of all the above lesion types. Our review is aimed at describing all the follicular disorders and gives an algorithm for diagnosing the common follicular disorders.

Abstract
Mutations in sarcoplasmic/endoplasmic reticulum calcium ATPase 2 (SERCA2) underlie Darier disease (DD), a dominantly inherited skin disorder characterized by loss of keratinocyte adhesion (acantholysis) and abnormal keratinization (dyskeratosis) resulting in characteristic mucocutaneous abnormalities. However, the molecular pathogenic mechanism by which these changes influence keratinocyte adhesion and viability remains unknown. We show here that SERCA2 protein is extremely sensitive to endoplasmic reticulum (ER) stress, which typically results in aggregation and insolubility of the protein. Depletion of ER calcium stores is not necessary for the aggregation but accelerates the progression. Systematic analysis of diverse mutants identical to those found in DD patients demonstrated that the ER stress initiator is the SERCA2 mutant protein itself. These SERCA2 proteins were found to be less soluble, to aggregate and to be more polyubiquitinylated. After transduction into primary human epidermal keratinocytes, mutant SERCA2 aggregates elicited ER stress, caused increased numbers of cells to round up and detach from the culture plate, and induced apoptosis. These mutant induced events were exaggerated by increased ER stress. Furthermore, knockdown SERCA2 in keratinocytes rendered the cells resistant to apoptosis induction. These features of SERCA2 and its mutants establish a mechanistic base to further elucidate the molecular pathogenesis underlying acantholysis and dyskeratosis in DD.

Abstract
The 22q11 deletion syndrome (22q11DS) is characterized by cognitive decline and increased risk of psychiatric disorders, mainly schizophrenia. The molecular mechanisms of neuronal dysfunction in cognitive symptoms of 22q11DS are poorly understood. Here, we report that a mouse model of 22q11DS, the Df(16)1/+ mouse, exhibits substantially enhanced short- and long-term synaptic plasticity at hippocampal CA3-CA1 synapses, which coincides with deficits in hippocampus-dependent spatial memory. These changes are evident in mature but not young animals. Electrophysiological, two-photon imaging and glutamate uncaging, and electron microscopic assays in acute brain slices showed that enhanced neurotransmitter release but not altered postsynaptic function or structure caused these changes. Enhanced neurotransmitter release in Df(16)1/+ mice coincided with altered calcium kinetics in CA3 presynaptic terminals and upregulated sarco(endo)plasmic reticulum calcium-ATPase type 2 (SERCA2). SERCA inhibitors rescued synaptic phenotypes of Df(16)1/+ mice. Thus, presynaptic SERCA2 upregulation may be a pathogenic event contributing to the cognitive symptoms of 22q11DS.

Abstract
Sarcoplasmic reticulum Ca(2+) ATPase (SERCA) is essential for muscle function by transporting Ca(2+) from the cytosol into the sarcoplasmic reticulum through ATP hydrolysis. In this report, the effects of substitution mutations on the isolated SERCA-nucleotide binding domain (SERCA-N) were studied using NMR. (15)N-(1)H HSQC spectra of substitution mutants at the nucleotide binding site, T441A, R560V, and C561A, showed chemical shift changes, primarily in residues adjacent to the mutation sites, indicating only local effects. Further, the patterns of chemical shift changes upon AMP-PNP binding to these mutants were similar to that of the wild type SERCA-N (WT). In contrast to these nucleotide binding site mutants, a mutant found in patients with Darier's disease, E412G, showed small but significant chemical shift changes throughout the protein and rapid precipitation. However, the AMP-PNP dissociation constant (∼2.5 mM) was similar to that of WT (∼3.8 mM). These results indicate that the E412G mutant retains its catalytic activity but most likely reduces its stability. Our findings provide molecular insight into previous clinical, physiological, and biochemical observations.

Abstract
We herein report a sporadic case of Darier's disease localized to the bilateral side of the neck in a 39-year-old Japanese woman. Several clinical variants of Darier's disease have so far been recognized including unilateral Darier's disease, localized Darier's disease, segmental Darier's disease and acral Darier's disease. Few cases of Darier's disease, restricted to sun-exposed areas such as the bilateral side of the neck, have been described in the published work. It remains controversial, however, whether ultraviolet exposure can induce the onset of Darier's disease. Our patient's skin lesions, which were resistant to previous treatment with corticosteroid, improved substantially with high-concentration tacalcitol lotion and sunscreen. This is the first report on the efficacy of topical tacalcitol lotion associated with sunscreen for the treatment of localized Darier's disease.

Abstract
INTRODUCTION Darier disease (DD) and Hailey-Hailey disease (HHD) are rare autosomal dominantly inherited genodermatoses with mutations in the respective genes, ATP2A2 and ATP2C1, that encode the respective calcium adenosine triphosphatases SERCA2 and PMRI/SPCA1. Lithium is an effective therapy used in psychiatry as prophylaxis against recurrent mania and to treat acute schizoaffective, impulsive, and alcoholic disorders. METHODS We discuss a patient with DD who claimed that her skin condition had flared after she was administered lithium therapy for bipolar disorder. DISCUSSION AND CONCLUSIONS DD may flare after lithium therapy, an association that has rarely been reported. Not uncommonly, DD has been observed to coexist with affective disorders, with reports of the bipolar disorder susceptibility locus cosegregating with a separate DD gene. A mechanism by which lithium worsens disease has recently been studied in rats. DD's coexistence with affective disorders and the mechanisms by which lithium may cause exacerbation of DD and HHD are reviewed.

Four novel ATP2A2 mutations in Slovenian patients with Darier disease. J Am Acad Dermatol 2010; 62:819-23.

Abstract
BACKGROUND Darier disease (DD) is an autosomal dominant genodermatosis caused by mutations in the ATP2A2 gene. It has been reported that depletion of Ca(2+) stores within the endoplasmic reticulum of keratinocytes is associated with impaired cell cycle regulation and terminal differentiation. Mechanical stress, heat, or UV irradiation might delay cell cycle exit and permit progression into the quiescent stage without repair. When there is associated DNA damage, this can lead to an accumulation of secondary somatic mutations and possible clonal proliferation of damaged keratinocyes within keratotic papules and plaques. OBJECTIVE We sought to present clinical, demographic, and genetic analysis of the cohort of Slovenian patients with DD, which represents 52% of DD patients in the country. METHODS We examined 28 Slovenians with DD and screened genomic DNA for ATP2A2 mutations and RNA for splice site mutations. RESULTS The estimated prevalence of the disease in Slovenia is 2.7/100.000. We identified 7 different ATP2A2 mutations, 4 of which are novel: A516P, R559G, 463-6del6, and 1762-6del18. We also found two previously described polymorphisms in intron XVIII (2741 + 54 G>A) and in exon 15 (2172 G>A; A724A), with allele frequencies of 64.15% and 11.32%, respectively. There was a history of perceptive deafness in two DD patients from two families. LIMITATIONS Analysis of SERCA2 expression, measurements of Ca(2+) uptake and their influence on desmosomal assembly in vitro would add additional value to the study. Although single-stranded conformational analysis (SSCP) is a common and accepted method for screening for the presence of mutations, it does miss 10% to 20% of mutations. CONCLUSIONS We identified 4 novel ATP2A2 mutations in Slovenian patients with DD. Deafness seems to be a new phenotypic characteristic of DD patients.

Abstract
AIMS Na(+)/K(+)-ATPase and Ca(2+)/Mg(2+)-ATPase are enzymes known to maintain intracellular gradients of ions that are essential for signal transduction. The aim of this study was to compare the activities of Na(+)/K(+)-ATPase and Ca(2+)/Mg(2+)-ATPase in postmortem brain samples from the cerebellum and frontal, temporal, parietal, and occipital cortices from autistic and age-matched control subjects. MAIN METHODS The frozen postmortem tissues from different brain regions of autistic and control subjects were homogenized. The activities of Na(+)/K(+)-ATPase and Ca(2+)/Mg(2+)-ATPase were assessed in the brain homogenates by measuring inorganic phosphorus released by the action of Na(+)/K(+)- and Ca(2+)/Mg(2+)-dependent hydrolysis of ATP. KEY FINDINGS In the cerebellum, the activities of both Na(+)/K(+)-ATPase and Ca(2+)/Mg(2+)-ATPase were significantly increased in the autistic samples compared with their age-matched controls. The activity of Na(+)/K(+)-ATPase but not Ca(2+)/Mg(2+)-ATPase was also significantly increased in the frontal cortex of the autistic samples as compared to the age-matched controls. In contrast, in other regions, i.e., the temporal, parietal and occipital cortices, the activities of these enzymes were similar in autism and control groups. SIGNIFICANCE The results of this study suggest brain-region specific increases in the activities of Na(+)/K(+)-ATPase and Ca(2+)/Mg(2+)-ATPase in autism. Increased activity of these enzymes in the frontal cortex and cerebellum may be due to compensatory responses to increased intracellular calcium concentration in autism. We suggest that altered activities of these enzymes may contribute to abnormal neuronal circuit functioning in autism.

Abstract
BACKGROUND Darrier's disease is a rare genodermatosis with a dominant autosomic penetrating variable transmission. The association between Darier's disease and neuropsychiatric disorders has been reported since 1996. Moreover, associations with mental retardation, schizophrenia, mood disorders and suicide have been reported. The discovery in 1999 of the ATP2A2 gene of Darier's disease, localised on chromosome 12, allowed significant advances notably in understanding the pathogenicity of these symptoms. MATERIAL AND METHODS In this article, we present the preliminary results of a clinical and genetic study of eight Tunisian families, involving dermatologists, psychiatrists and geneticians. Eight patients with Darier's disease and their first degree relatives were included in the study after they had given their written consent. Thirty-five subjects were examined, 23 of them had Darier's disease. All patients were submitted to a complete clinical examination; notably dermatological screening, genetic inquiry and blood tests for haplotype analysis. Only 13 of them underwent a psychiatric examination. RESULTS The psychiatric examination was carried out only in 13 patients with Darier's disease, who revealed neuropsychiatric symptoms with a frequency of 61.1% (8/13). Two patients presented mild mental retardation; six patients had mood disorders, three of them belonged to the same family (two had recurrent depression, four belonged to the bipolar spectrum [2 bipolar disorder type 2, 2 cyclothymia]). The coexpression of the two distinct phenotypes (Darier's disease and bipolar disease), within the same three members' of the family of our study, suggests the existence of a genetic linkage between the two diseases, as has been reported in the literature.

Abstract
The ATP2A2 gene encodes Ca2+-dependent ATPase, the dysfunction of which causes Darier disease. In this study, we analyzed the promoter structure of the human ATP2A2 gene using primary normal human keratinocytes (NHK). Reporter assays showed that deletion of -550/-529, -488/-472, -390/-362, or -42/-21 resulted in a significant decrease in human ATP2A2 promoter activity. Electrophoretic mobility shift assay (EMSA) showed that Sp1 is a transcription factor that binds to the -550/-529 and -488/-472 regions of the promoter. Chromatin immunoprecipitation (ChIP) assay demonstrated that Sp1, but not Sp3, binds to the promoter region of the ATP2A2 gene in NHK cells in vivo. Knockdown of Sp1 expression by small interfering RNA resulted in a marked reduction in ATP2A2 promoter activity and ATP2A2 mRNA levels in NHK, suggesting that Sp1 positively transactivates the ATP2A2 promoter in NHK. This is early evidence demonstrating that Sp1 plays an important and positive role in ATP2A2 gene expression in NHK in vivo and in vitro.

Abstract
Ca(2+) influx evoked across the plasma membrane upon internal store depletion is essential for a myriad of cellular functions including gene expression, cell proliferation, differentiation and even apoptosis. Darier's disease (DD), an autosomal dominant inherited disorder of the skin, arising due to mutations in the isoform 2 of the sarco (endo) plasmic reticulum Ca(2+) ATPase (SERCA2), exemplifies an anomaly of Ca(2+) signaling disturbances. Owing to loss of function mutations in SERCA2, keratinocytes in DD patients have a reduced pool of endoplasmic reticulum (ER) Ca(2+). Importantly, the status of ER Ca(2+) is critical for the activation of a class of plasma membrane Ca(2+) channels referred to as store operated Ca(2+) channels (SOCs). The widely expressed transient receptor potential (TRP) family of channels is proposed to be SOCs. In this review we discuss DD from the viewpoint of Ca(2+) signaling and present a potential role for TRPC1 in the disease pathogenesis.

Abstract
BACKGROUND Aberrant intracellular calcium (Ca2+) signaling in patients with bipolar-I disorder (BD-I) suggests disturbed endoplasmic reticulum (ER) function in BD. We examined whether the ER stress response is altered in BD-I patients and the relationship to basal intracellular Ca2+ levels ([Ca2+]B), in B lymphoblasts (BLCLs) from BD-I patients. METHODS Endoplasmic reticulum stress-induced X-box binding protein 1 (XBP1), C/EBP homologous protein (CHOP), and GRP78 expression in BLCLs from BD-I subjects stratified on elevated or normal [Ca2+]B and control subjects were determined by real-time quantitative reverse transcription polymerase chain reaction. The XBP1 -116C/G polymorphism, which impairs the XBP1 loop in the ER stress response, were genotyped with a TaqMan-based assay. RESULTS Compared with control subjects, thapsigargin- and tunicamycin-induced increases in XBP1 and CHOP but not GRP78 messenger RNA levels were significantly lower in BD-I patients. However, induction of these genes did not differ significantly in the two BD-I subgroups stratified on [Ca2+]B. Furthermore, the attenuated XBP1 induction cannot be explained solely by differences of XBP1 -116C/G genotype frequency. CONCLUSIONS Our findings suggest that the ER stress response is impaired in BD-I patients but irrespective of altered intracellular Ca2+ homeostasis as reflected in elevated [Ca2+]B. Moreover, an effect of XBP1 -116C/G polymorphism could not account for the attenuated XBP1 induction in bipolar-I disorder observed in this study.
