Abstract
Mutations of proline-rich transmembrane protein 2 (PRRT2) lead to dyskinetic disorders such as paroxysmal kinesigenic dyskinesia (PKD), which is characterized by attacks of involuntary movements precipitated by suddenly initiated motion, and some convulsive disorders. Although previous studies have shown that PKD might be caused by cerebellar dysfunction, PRRT2 has not been sufficiently analyzed in some motor-related regions, including the basal ganglia, where dopaminergic neurons are most abundant in the brain. Here, we generated several types of Prrt2 knock-in (KI) mice harboring mutations, such as c.672dupG, that mimics the human pathological mutation c.649dupC and investigated the contribution of Prrt2 to dopaminergic regulation. Regardless of differences in the frameshift sites, all truncating mutations abolished Prrt2 expression within the striatum and cerebral cortex, consistent with previous reports of similar Prrt2 mutant rodents, confirming the loss-of-function nature of these mutations. Importantly, administration of l-dopa, a precursor of dopamine, exacerbated rotarod performance, especially in Prrt2-KI mice. These findings suggest that dopaminergic dysfunction in the brain by the PRRT2 mutation might be implicated in a part of motor symptoms of PKD and related disorders.

Abstract
Background: Neurofibromatosis type 1 (NF1) is a hereditary cancer syndrome characterized by multiple café-au-lait macules on the skin. Lymphoproliferative malignancies associated with NF1 are limited, although the most common are brain tumors. Case presentation: A 22-year-old woman with NF1 was admitted due to abdominal pain and bloody diarrhea. Her laboratory data exhibited macrocytic anemia and elevated IgA levels. Image studies showed diffuse increased wall thickening in the transverse and descending colon without lymphadenopathy and hepatosplenomegaly. A colonoscopy revealed a hemorrhagic ulcerated mass. Pathological analysis of the tumor tissues confirmed IgA-expressing mucosa-associated lymphoid tissue (MALT) lymphoma with histological transformation. Moreover, whole-exome sequencing in tumor tissues and peripheral blood mononuclear cells identified a somatic frameshift mutation of the A20 gene, which represents the loss of function. The patient responded well to R-CHOP chemotherapy, but the disease relapsed after 1 year, resulting in a lethal outcome. Conclusions: MALT lymphoma in children and young adults is extremely rare and is possibly caused by acquired genetic changes. This case suggests a novel association between hereditary cancer syndrome and early-onset MALT lymphoma.

Abstract
Adult T-cell leukemia/lymphoma (ATL) is an intractable hematological malignancy with extremely poor prognosis. Recent studies have revealed that super-enhancers (SE) play important roles in controlling tumor-specific gene expression and are potential therapeutic targets for neoplastic diseases including ATL. Cyclin-dependent protein kinase (CDK) 9 is a component of a complex comprising transcription factors (TFs) that bind the SE region. Alvocidib is a CDK9 inhibitor that exerts antitumor activity by inhibiting RNA polymerase (Pol) II phosphorylation and suppressing SE-mediated, tumor-specific gene expression. The present study demonstrated that alvocidib inhibited the proliferation of ATL cell lines and tumor cells from patients with ATL. RNA sequencing (RNA-Seq) and chromatin immunoprecipitation sequencing (ChIP-Seq) disclosed that SE regulated IRF4 in the ATL cell lines. Previous studies showed that IRF4 suppression inhibited ATL cell proliferation. Hence, IRF4 is a putative alvocidib target in ATL therapy. The present study revealed that SE-mediated IRF4 downregulation is a possible mechanism by which alvocidib inhibits ATL proliferation. Alvocidib also suppressed ATL in a mouse xenograft model. Hence, the present work demonstrated that alvocidib has therapeutic efficacy against ATL and partially elucidated its mode of action. It also showed that alvocidib is promising for the clinical treatment of ATL and perhaps other malignancies and neoplasms as well.

Abstract
The choroid plexus (ChP) is the center of soluble factor secretion into the cerebrospinal fluid in the central nervous system. It is known that various signaling factors secreted from the ChP are involved in the regulation of brain development and homeostasis. Intriguingly, the size of the ChP was prominently expanded in the brains of primates, including humans, suggesting that the expansion of the ChP contributed to mammalian brain evolution, leading to the acquisition of higher intelligence and cognitive functions. To address this hypothesis, we established transgenic (Tg) systems using regulatory elements that direct expression of candidate genes in the ChP. Overexpression of sonic hedgehog (Shh) in the developing ChP led to the expansion of the ChP with greater arborization. Shh produced in the ChP caused an increase in neural stem cells (NSCs) in the neocortical region, leading to the expansion of ventricles, ventricular zone, neocortical surface area, and neocortical surface folding. These findings suggest that the activation of Shh signaling via its enhanced secretion from the developing ChP contributed to the evolution of the neocortex. Furthermore, we found that Shh produced in the ChP enhanced NSC proliferation in the postnatal Tg brain, demonstrating that our Tg system can be used to estimate the effects of candidate factors secreted from the ChP on various aspects of brain morphogenesis and functions.

Abstract
Kabuki syndrome (KS) is a rare congenital disorder commonly complicated by humoral immunodeficiency. Patients with KS present with mutation in the histone-lysine N-methyltransferase 2D (KMT2D) gene. Although various KMT2D mutations are often identified in lymphoma and leukemia, those encountered in aplastic anemia (AA) are limited. Herein, we present the case of a 45-year-old Japanese man who developed severe pancytopenia and hypogammaglobulinemia. He did not present with any evident malformations, intellectual disability, or detectable levels of autoantibodies. However, B-cell development was impaired. Therefore, a diagnosis of very severe AA due to a hypoplastic marrow, which did not respond to granulocyte colony-stimulating factor, was made. The patient received umbilical cord blood transplantation but died from a Pseudomonas infection before neutrophil engraftment. Trio whole-exome sequencing revealed a novel missense heterozygous mutation c.15959G >A (p.R5320H) in exon 50 of the KMT2D gene. Moreover, Sanger sequencing of peripheral blood and bone marrow mononuclear cells and a skin biopsy specimen obtained from this patient identified this heterozygous mutation, suggesting that de novo mutation associated with KS occurred in the early embryonic development. Our case showed a novel association between KS mutation and adult-onset AA.

Abstract
Mutations in ITPR1 cause ataxia and aniridia in individuals with Gillespie syndrome (GLSP). However, the pathogenic mechanisms underlying aniridia remain unclear. We identified a de novo GLSP mutation hotspot in the 3'-region of ITPR1 in five individuals with GLSP. Furthermore, RNA-sequencing and immunoblotting revealed an eye-specific transcript of Itpr1, encoding a 218amino acid isoform. This isoform is localized not only in the endoplasmic reticulum, but also in the nuclear and cytoplasmic membranes. Ocular-specific transcription was repressed by SOX9 and induced by MAF in the anterior eye segment (AES) tissues. Mice lacking seven base pairs of the last Itpr1 exon exhibited ataxia and aniridia, in which the iris lymphatic vessels, sphincter and dilator muscles, corneal endothelium and stroma were disrupted, but the neural crest cells persisted after completion of AES formation. Our analyses revealed that the 218-amino acid isoform regulated the directionality of actin fibers and the intensity of focal adhesion. The isoform might control the nuclear entry of transcriptional regulators, such as YAP. It is also possible that ITPR1 regulates both AES differentiation and muscle contraction in the iris.

Abstract
Kabuki syndrome is characterized by multiple systemic anomalies and intellectual disability. It is complicated with immunodeficiencies and autoimmune disorders. The syndrome is caused by a mutation in the KMT2D gene. We herein report a case of a Kabuki syndrome with developing immune thrombocytopenic purpura (ITP) and progressive splenomegaly. Laparoscopic splenectomy was performed and the patients' symptoms quickly disappeared with platelet recovery. After this operation, the patient had no severe complications. A sequence analysis of the KMT2D gene identified a pathogenic mutation frequently associated with ITP. Laparoscopic splenectomy is therefore considered to be a good therapeutic option for recurrent ITP and symptomatic splenomegaly with Kabuki syndrome.

Abstract
Although the association between radiation exposure and thyroid carcinogenesis is epidemiologically evident, 'true' radiation-induced cancers cannot be identified from biological evidence of radiation-associated cases. To assess the individual risk for thyroid cancer due to radiation exposure, we aimed to identify biomarkers that are specifically altered during thyroid carcinogenesis after irradiation in a time-dependent manner in an animal model. Thyroid glands were obtained from rats (n = 175) at 6-16 months after local X-ray (0.1-4 Gy) irradiation of the neck at 7 weeks of age. The gene expression profile in thyroid glands was comprehensively analyzed using RNA microarray. Subsequently, the expression levels of the genes of interest were verified using droplet digital PCR (ddPCR). The expression level of candidate genes as biomarkers for irradiated thyroid was examined in a randomized, controlled, double-blind validation study (n = 19) using ddPCR. The incidence of thyroid cancer increased in a dose- and time-dependent manner and was 33% at 16 months after irradiation with 4 Gy. The Ki-67 labeling index in non-tumorous thyroid was significantly higher in the exposed group than in the control. Comprehensive analysis identified radiation-dependent alteration in 3329 genes. Among them, ddPCR revealed a stepwise increase in CDKN1A expression from early pre-cancerous phase in irradiated thyroid compared to that in the control. The irradiated thyroids were accurately distinguished (positive predictive value 100%, negative predictive value 69%) using 11.69 as the cut-off value for CDKN1A/β-actin. Thus, CDKN1A expression can be used as a biomarker for irradiated thyroid glands at the pre-cancerous phase.

Abstract
An expanded and folded neocortex is characteristic of higher mammals, including humans and other primates. The neocortical surface area was dramatically enlarged during the course of mammalian brain evolution from lissencephalic to gyrencephalic mammals, and this bestowed higher cognitive functions especially to primates, including humans. In this study, we generated transgenic (Tg) mice in which the expression of Sonic hedgehog (Shh) could be controlled in neural stem cells (NSCs) and neural progenitors by using the Tet-on system. Shh overexpression during embryogenesis promoted the symmetric proliferative division of NSCs in the neocortical region, leading to the expansion of lateral ventricles and tangential extension of the ventricular zone. Moreover, Shh-overexpressing Tg mice showed dramatic expansion of the neocortical surface area and exhibited a wrinkled brain when overexpression was commenced at early stages of neural development. These results indicate that Shh is able to increase the neocortical NSCs and contribute to expansion of the neocortex.

Abstract
N-cadherin is a homophilic cell adhesion molecule that stabilizes excitatory synapses, by connecting pre- and post-synaptic termini. Upon NMDA receptor (NMDAR) activation by glutamate, membrane-proximal domains of N-cadherin are cleaved serially by a-disintegrin-and-metalloprotease 10 (ADAM10) and then presenilin 1(PS1, catalytic subunit of the γ-secretase complex). To assess the physiological significance of the initial N-cadherin cleavage, we engineer the mouse genome to create a knock-in allele with tandem missense mutations in the mouse N-cadherin/Cadherin-2 gene (Cdh2 R714G, I715D, or GD) that confers resistance on proteolysis by ADAM10 (GD mice). GD mice showed a better performance in the radial maze test, with significantly less revisiting errors after intervals of 30 and 300 s than WT, and a tendency for enhanced freezing in fear conditioning. Interestingly, GD mice reveal higher complexity in the tufts of thorny excrescence in the CA3 region of the hippocampus. Fine morphometry with serial section transmission electron microscopy (ssTEM) and three-dimensional (3D) reconstruction reveals significantly higher synaptic density, significantly smaller PSD area, and normal dendritic spine volume in GD mice. This knock-in mouse has provided in vivo evidence that ADAM10-mediated cleavage is a critical step in N-cadherin shedding and degradation and involved in the structure and function of glutamatergic synapses, which affect the memory function.

Abstract
COL27A1 encodes a collagen type XXVII alpha 1 chain. It is the product of this gene that provides the structural support of connective tissue and is reported to be the causative gene of Steel syndrome (OMIM #615155). The primary symptoms of patients with this defect are consistent with systemic bone disease; however, recent reports note findings of intellectual disability and hearing loss. In this study, we identified novel COL27A1 compound heterozygous variants in two brothers with rhizomelia and congenital hip dislocation as well as dental and genital abnormalities that have not yet been reported in Steel syndrome. This variant, of maternal origin, caused an amino acid substitution of arginine for glycine, c.2026G>C or p.G676R, in the collagen helix domain, which is assumed to damage the structure of the helix. The paternally transmitted variant, c.2367G>A, is located at the 3' end of exon 12, and cDNA analysis revealed a splicing alteration. These novel, compound heterozygous COL27A1 variants might indicate an association of the gene with tooth and genital abnormalities.

Abstract
BACKGROUND Inositol-requiring enzyme 1α (IRE1α), along with protein kinase R-like endoplasmic reticulum kinase (PERK), is a principal regulator of the unfolded protein response (UPR). Recently, the 'mono'-specific IRE1α inhibitor, kinase-inhibiting RNase attenuator 6 (KIRA6), demonstrated a promising effect against multiple myeloma (MM). Side-stepping the clinical translation, a detailed UPR phenotype in patients with MM and the mechanisms of how KIRA8 works in MM remains unclear. METHODS We characterized UPR phenotypes in the bone marrow of patients with newly diagnosed MM. Then, in human MM cells we analyzed the possible anti-tumor mechanisms of KIRA8 and a Food and Drug Administration (FDA)-approved drug, nilotinib, which we recently identified as having a strong inhibitory effect against IRE1α activity. Finally, we performed an RNA-sequence analysis to detect key IRE1α-related molecules against MM. RESULTS We illustrated the dominant induction of adaptive UPR markers under IRE1α over the PERK pathway in patients with MM. In human MM cells, KIRA8 decreased cell viability and induced apoptosis, along with the induction of C/EBP homologous protein (CHOP); its combination with bortezomib exhibited more anti-myeloma effects than KIRA8 alone. Nilotinib exerted a similar effect compared with KIRA8. RNA-sequencing identified Polo-like kinase 2 (PLK2) as a KIRA8-suppressed gene. Specifically, the IRE1α overexpression induced PLK2 expression, which was decreased by KIRA8. KIRA8 and PLK2 inhibition exerted anti-myeloma effects with apoptosis induction and the regulation of cell proliferation. Finally, PLK2 was pathologically confirmed to be highly expressed in patients with MM. CONCLUSION Dominant activation of adaptive IRE1α was established in patients with MM. Both KIRA8 and nilotinib exhibited anti-myeloma effects, which were enhanced by bortezomib. Adaptive IRE1α signaling and PLK2 could be potential therapeutic targets and biomarkers in MM.

Abstract
BACKGROUND It is clinically emergent to further understand the pathological mechanism to advance therapeutic strategy for endocrine tumors. A high amount of secretory protein with tumorigenic triggers are thought to induce unfolded protein response in endoplasmic reticulum in endocrine tumors, but its evidence is limited. CASE PRESENTATION A 40-year-old woman had an approximately 10-year history of intermittent headaches. After the incidental detection of a mass in her right adrenal gland by CT scan, she was admitted to our hospital. She had been diagnosed as type 1 Waardenburg syndrome with the symptoms of dystopia canthorum, blue iris, and left sensorineural hearing loss. Urinary catecholamine levels were markedly elevated. 123I-MIBG scintigraphy showed uptake in the mass in her adrenal gland. After the adrenalectomy, her headaches disappeared and urinary catecholamine levels decreased to normal range within 2 weeks. Genome sequencing revealed germline mutation of c.A175T (p.Ile59Phe) in transcription factor PAX3 gene and somatic novel mutation of c.1893_1898del (p. Asp631_Leu633delinsGlu) in proto-oncogene RET in her pheochromocytoma. RNA expression levels of RET were increased 139 times in her pheochromocytoma compared with her normal adrenal gland. Those of unfolded protein response markers, Bip/GRP78, CHOP, ATF4, and ATF6, were also increased in the pheochromocytoma. CONCLUSION We report a rare case of pheochromocytoma with type 1 Waardenburg syndrome. This is the first case to show the activation of unfolded protein response in the pheochromocytoma with the novel somatic mutation in RET gene. Our findings may support that unfolded protein response is activated in endocrine tumors, which potentially could be a candidate of therapeutic target.

Abstract
Background and Aims
Anti-glomerular basement membrane (GBM) glomerulonephritis (GN), characterized by glomerular crescent formation, requires early treatment because of poor prognosis. Hydroxychloroquine (HCQ) is a well-known antimalarial drug. In addition, it has immunomodulatory, anti-inflammatory, and autophagy inhibitory effects and its recognized in the treatment of autoimmune disease such as SLE. However, its effect for anti-GBM GN is unknown. In this study, we investigated the effect of HCQ against anti-GBM GN in rats.
Method
7 week old male, WKY rats were induced by the administration of anti-GBM serum (50μg/rat). We administered either HCQ (50mg/kg) or vehicle (Phosphate-buffered saline) from day 0 to day 7 after the induction of nephritis. Renal function was assessed by measuring serum creatinine, proteinuria, hematuria. Urine was collected for 24 hours on day 1, 3, 5, and 7. Rats were sacrificed on day 7 after induction of anti-GBM GN. Renal histological changes were assessed by PAS staining, and Masson trichrome stain, and macrophage was assessed by ED-1 stain. Mitogen-Activated Protein Kinase (MAPK) was evaluated by western blotting (WB) and inflammatory cytokines were evaluated by ELISA using urine.
Results
HCQ treatment suppressed renal function decline. Histologically, extracellular and intracellular cells were increased from day 1, fibrinoid necrosis and ED-1 positive cells were observed from day 3. Rats with anti-GBM GN had high levels of interferon-α, interleukin-6, monocyte chemotactic protein-1, and tumor necrosis factor-α. These changes were significantly suppressed by HCQ. In addition, HCQ suppressed phosphorylation of JNK/p38 MAPK.
Conclusion
Our study showed that HCQ could attenuate anti-GBM GN and have an anti-inflammatory effect by inhibiting JNK/p38 MAPK activation. HCQ may have therapeutic potential in anti-GBM GN.

Abstract
Background: Camurati-Engelmann disease (CED)is a rare sclerosing bone disorder. The skull and the diaphyses of the long tubular bones are mainly affected. The symptom developed in childhood and patients suffer from bone pain, easy fatigability, and decreased muscle mass and weakness. CED is caused by mutations in the transforming growth factorβ1 (TGFβ1)gene on chromosome 19q13.113.3. This condition is inherited in an autosomal dominant pattern. Case: A 20- year-old male. He has a so-called marfanoid habitus with long and narrow limbs. At the age of 19,he presented pain in lower limb, then walking became difficult. None of his relatives had similar symptoms. In biochemical tests,calcium, Phosphorus and bone-related hormones levels were all in the normal range. 25(OH)vitamin D levels were low probably due to his eating habits. On radiological evaluation, X-ray showed thickening of the bone cortex of the bilateral tibia. Bone scintigraphy revealed markedly increased tracer uptake in the bilateral temporal bone, femur, and tibia. Based on clinical and radiological features CED was suspected. Sequence analysis of the transforming growth factor β1 (TGFB1)gene revealed a previously reported pathological variant (p.R218H). Discussion: CED is a rare pan-ethnic condition with more than 300 published cases worldwide. Although this case was difficult to diagnose because there was no family history and the onset of adulthood not childhood, this disease was suspected due to the typical localization of affected bone lesions by bone scintigraphy and was diagnosed by genetic testing. The majority of CED are missense variants in exon 4 leading to single amino acid substitutions in the encoded protein. Exon 4 encodes a latency-associated peptide (LAP) that suppresses the activity of TGF-β1 protein. No consensus management guidelines have been developed to date. Treatment with corticosteroids may relieve the pain, improve the muscle weakness and fatigue. Recently, the efficacy of losartan has been reported in some patients. Conclusion: Here we report a de novo case of CED diagnosed by genetic testing. Osteosclerotic diseases are very rare and are often difficult to diagnose. Genetic testing plays an important role in confirming the diagnosis.

Abstract
Mutations in IRF6, TFAP2A and GRHL3 cause orofacial clefting syndromes in humans. However, Tfap2a and Grhl3 are also required for neurulation in mice. Here, we found that homeostasis of Irf6 is also required for development of the neural tube and associated structures. Over-expression of Irf6 caused exencephaly, a rostral neural tube defect, through suppression of Tfap2a and Grhl3 expression. Conversely, loss of Irf6 function caused a curly tail and coincided with a reduction of Tfap2a and Grhl3 expression in tail tissues. To test whether Irf6 function in neurulation was conserved, we sequenced samples obtained from human cases of spina bifida and anencephaly. We found two likely disease-causing variants in two samples from patients with spina bifida. Overall, these data suggest that the Tfap2a-Irf6-Grhl3 genetic pathway is shared by two embryologically distinct morphogenetic events that previously were considered independent during mammalian development. In addition, these data suggest new candidates to delineate the genetic architecture of neural tube defects and new therapeutic targets to prevent this common birth defect.

Abstract
Ionizing radiation is a risk factor for myeloid neoplasms including myelodysplastic syndromes (MDS), and atomic bomb survivors have been shown to have a significantly higher risk of MDS. Our previous analyses demonstrated that MDS among these survivors had a significantly higher frequency of complex karyotypes and structural alterations of chromosomes 3, 8, and 11. However, there was no difference in the median survival time between MDS among survivors compared with those of de novo origin. This suggested that a different pathophysiology may underlie the causative genetic aberrations for those among survivors. In this study, we performed genome analyses of MDS among survivors and found that proximally exposed patients had significantly fewer mutations in genes such as TET2 along the DNA methylation pathways, and they had a significantly higher rate of 11q deletions. Among the genes located in the deleted portion of chromosome 11, alterations of ATM were significantly more frequent in proximally exposed group with mutations identified on the remaining allele in 2 out of 5 cases. TP53, which is frequently mutated in therapy-related myeloid neoplasms, was equally affected between proximally and distally exposed patients. These results suggested that the genetic aberration profiles in MDS among atomic bomb survivors differed from those in therapy-related and de novo origin. Considering the role of ATM in DNA damage response after radiation exposure, further studies are warranted to elucidate how 11q deletion and aberrations of ATM contribute to the pathogenesis of MDS after radiation exposure.

Abstract
Invasive pulmonary aspergillosis (IPA) patients with non-hematological malignancy are far less than with hematological malignancy patients. We encountered a very rare case of IPA in which type 1 diabetes was the only conceivable risk factor. Further, according to the diagnostic categories of the European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG) criteria for IPA, the frequency of proven diagnosis is very low. Here we report a proven IPA, which rapidly developed when the patient with type 1 diabetes was being treated for diabetic ketoacidosis, which was successfully treated with the combination therapy of voriconazole (VRCZ) and micafungin (MCFG), based on early diagnosis using bronchoscopy.

Abstract
OBJECTIVE The pathogenesis of nonsyndromic cleft lip with or without cleft palate (NSCL ± P) and nonsyndromic cleft palate only (NSCP) may be associated with genetic factors. Although some predisposing genes/loci have been reported, their attributable risk is too small to be clinically meaningful. To clarify the genetic causes and mechanisms of NSCL±P or NSCP, we conducted mutation analysis of target genes using a next-generation sequencing (NGS) approach. METHODS The target genes, IRF6, WNT5A, WNT9B, TP63, MSX1, TFAP2A, PAX9, DLX3, DLX4, and MN1, were selected based on previous reports of potential associations with the development of NSCL±P or NSCP from genome-wide association studies and candidate gene analyses. Mutation analysis was conducted using NGS on 74 Japanese trios (patient and parents) and 18 Japanese patients only families. RESULTS We detected single-nucleotide variants (SNVs) for 7 genes: IRF6, DLX4, WNT5A, TFAP2A, WNT9B, TP63, and PAX9. The SNVs found on IRF6 and DLX4 were missense mutations, whereas those identified on WNT5A, TFAP2A, WNT9B, TP63, and PAX9 were rare variants in the noncoding region; no de novo mutation was identified in the trio samples. The amino acid change on DLX4 was detected within the highly conserved homeodomain and was predicted to have a deleterious impact on the protein function by in silico analysis. CONCLUSIONS The DLX4 missense mutation c.359C>T (Pro120Leu) was found in 1 Japanese patient with NSCL±P and was located in the homeodomain region. This mutation likely plays a role in the development of NSCL±P in the Japanese population.

Abstract
Objective To identify genes related to normal-pressure hydrocephalus (NPH) in one Japanese family with several members with NPH. Methods We performed whole-exome sequencing (WES) on a Japanese family with multiple individuals with NPH and identified a candidate gene. Then we generated knockout mouse using CRISPR/Cas9 to confirm the effect of the candidate gene on the pathogenesis of hydrocephalus. Results In WES, we identified a loss-of-function variant in CFAP43 that segregated with the disease. CFAP43 encoding cilia- and flagella-associated protein is preferentially expressed in the testis. Recent studies have revealed that mutations in this gene cause male infertility owing to morphologic abnormalities of sperm flagella. We knocked out mouse ortholog Cfap43 using CRISPR/Cas9 technology, resulting in Cfap43-deficient mice that exhibited a hydrocephalus phenotype with morphologic abnormality of motile cilia. Conclusion Our results strongly suggest that CFAP43 is responsible for morphologic or movement abnormalities of cilia in the brain that result in NPH.

Abstract
Aggressive natural killer cell leukemia (ANKL) is a rare neoplasm characterized by the systemic infiltration of Epstein-Barr virus (EBV)-associated NK cells, and rapidly progressive clinical course. We report the case of a 45-year-old man with intellectual disability who developed ANKL, and describe the identification of a novel genetic mutation of coiled-coil domain-containing 22 (CCDC22). He presented with persistent fever, severe pancytopenia, and hepatosplenomegary. Following bone marrow aspiration, numerous hemophagocytes were identified. High EBV viral load was detected in NK cells fractionation by qPCR. The initial diagnosis was EBV-related hemophagocytic lymphohistiocytosis (EBV-HLH). A combination of immunosuppressive drugs and chemotherapy was administered, but was unsuccessful in controlling the disease. Therefore, he was treated with HLA-matched related allogeneic hematopoietic stem cell transplantation. However, his condition deteriorated within 30 days, resulting in fatal outcome. Autopsy revealed many EBV-infected NK cells infiltrating major organs, consistent with ANKL. Furthermore, whole-exome sequencing identified a novel missense mutation of the CCDC22 gene (c.112G>A, p.V38M), responsible for X-linked intellectual disability (XLID). CCDC22 has been shown to play a role in NF-κB activation. Our case suggests that CCDC22 mutation might be implicated in pathogenesis of EBV-HLH and NK-cell neoplasms as well as XLID via possibly affecting NF-κB signaling.

Abstract
Background Relapse of cryptogenic organizing pneumonia (COP) may lead to poor long-term prognosis and necessitates multiple rounds of steroid treatment with potential adverse effects. The objective of this study is to identify predictive factors of COP relapse by comparing demographic and clinical variables between relapse and non-relapse groups. Methods During 2008–2013, 33 COP patients were treated, of which 23 (69.7%) and 10 patients (30.3%) were assigned to the non-relapse and relapse group, respectively. From medical records, we compared the following variables at initial episode: clinical characteristics, serum parameters, chest CT scan findings, and steroid treatment. Results Clinical characteristics, cumulative prednisone dose, and steroid treatment duration were similar between groups. In univariate analysis, alternatively, the proportion of patients with bilateral shadow pattern, traction bronchiectasis, and partial remission after steroid treatment was significantly higher in the relapse group. These differences were not significant by multivariate Cox regression analysis. Conclusions We identified radiographic findings, such as bilateral shadow pattern, traction bronchiectasis, and partial remission, may have possibility of predictive factors for COP relapse. Larger-scale studies are required to confirm if any are independent predictors of COP relapse.

Abstract
Special AT-rich sequence-binding protein 2 (SATB2)-associated syndrome (SAS) is characterized by alterations of SATB2. Its clinical features include intellectual disability and craniofacial abnormalities, such as cleft palate, dysmorphic features, and dental abnormalities. Here, we describe three previously undiagnosed, unrelated patients with SAS who exhibited dental abnormalities, including multiple odontomas. Although isolated odontomas are common, multiple odontomas are rare. Individuals in families 1 and 3 underwent whole-exome sequencing. Patient 2 and parents underwent targeted amplicon sequencing. On the basis of the hg19/GRCh37 reference and the RefSeq mRNA NM_001172517, respective heterozygous mutations were found and validated in Patients 1, 2, and 3: a splice-site mutation (chr2:g.200137396C > T, c.1741-1G > A), a nonsense mutation (chr2:g.200213750G > A, c.847C > T, p.R283*), and a frame-shift mutations (chr2:g.200188589_200188590del, c.1478_1479del, p.Q493Rfs*19). All mutations occurred de novo. The mutations in Patients 1 and 3 were novel; the mutation in Patient 2 has been described previously. Tooth mesenchymal cells derived from Patient 2 showed diminished SATB2 expression. Multiple odontomas were evident in the patients in this report; however, this has not been recognized previously as a SAS-associated phenotype. We propose that multiple odontomas be considered as an occasional manifestation of SAS.

Abstract
In acute myeloid leukemia (AML), patients may harbor pre-leukemic hematopoietic stem cells (HSCs) containing some, but not all, of the mutations observed in the leukemic cells. These pre-leukemic HSCs may survive induction chemotherapy and contribute to AML relapse by obtaining additional mutations. We report here an acute monoblastic leukemia (AMoL) patient who later developed an unclassifiable myeloproliferative neoplasm (MPN-U). Whole-exome sequencing and cluster analysis demonstrated the presence of three distinct major clones during the clinical course: (1) an AMoL clone with ASXL1, CBL, and NPM1 somatic mutations, likely associated with the pathogenesis, and GATA2, SRSF2, and TET2 mutations, (2) an AMoL remission clone, with mutated GATA2, SRSF2, and TET2 only (possibly the founding clone (pre-leukemic HSC) that survived chemotherapy), (3) a small subclone which had JAK2 mutation during the AMoL remission, appearing at MPN-U manifestation with additional mutations. These findings suggest that pre-leukemic HSCs in AML patients may give rise to non-AML myeloid malignancies. This is the first report to analyze the clonal evolution from AMoL to MPN-U, which may provide new insight into the development of myeloid malignancies.

Abstract
Panic disorder (PD) is characterized by recurrent and unexpected panic attacks, subsequent anticipatory anxiety, and phobic avoidance. Recent epidemiological and genetic studies have revealed that genetic factors contribute to the pathogenesis of PD. We performed whole-exome sequencing on one Japanese family, including multiple patients with panic disorder, which identified seven rare protein-altering variants. We then screened these genes in a Japanese PD case-control group (384 sporadic PD patients and 571 controls), resulting in the detection of three novel single nucleotide variants as potential candidates for PD (chr15: 42631993, T>C in GANC; chr15: 42342861, G>T in PLA2G4E; chr20: 3641457, G>C in GFRA4). Statistical analyses of these three genes showed that PLA2G4E yielded the lowest p value in gene-based rare variant association tests by Efficient and Parallelizable Association Container Toolbox algorithms; however, the p value did not reach the significance threshold in the Japanese. Likewise, in a German case-control study (96 sporadic PD patients and 96 controls), PLA2G4E showed the lowest p value but again did not reach the significance threshold. In conclusion, we failed to find any significant variants or genes responsible for the development of PD. Nonetheless, our results still leave open the possibility that rare protein-altering variants in PLA2G4E contribute to the risk of PD, considering the function of this gene.

Abstract
We herein present a case of a 71‐year‐old woman with primary Sjogren's syndrome (SjS), who developed bilateral pleural effusion and ground glass opacity during treatment with low‐dose prednisolone. The pleural effusion and bronchoalveolar lavage fluid revealed elevation of lymphocytes. Thoracoscopic pleural biopsy showed infiltration of lymphocytes with no evidence of other diseases, confirming SjS‐related pleuritis. Therefore, we initiated 20 mg prednisolone and pleural effusion was rapidly resolved. Our results indicate that SjS can be rarely complicated with pleuritis. In addition, thoracoscopic pleural biopsy and a rapid response to steroid treatment would be helpful for diagnosing SjS‐related pleuritis.

Abstract
Zusammenfassung
Gegenstand und Ziel: Hyperketonämien treten in Milchviehbeständen scheinbar vermehrt im Frühsommer auf. Ziel der Untersuchung war, unter den Bedingungen des Landes Mecklenburg-Vorpommern (MV) festzustellen, ob diese Häufung statistisch nachweisbar ist und zu welchem Anteil es sich bei den beschriebenen Fällen um alimentär oder energiemangelbedingte Hyperketonämien handelt. Material und Methoden: Anhand der in 5 Jahren gewonnenen Blutproben von 7081 Kühen aus MV wurde der jahreszeitliche Verlauf der Hyperketonämie-Prävalenz untersucht. Konzentrationen von ≥ 1,0 mmol/l β-Hydroxybuttersäure (BHB) bzw. ≥ 5,0 μmol/l Bilirubin wurden als Hyperketonämie (Ket) bzw. Hyperbilirubinämie (Bili) gewertet. Der Anstieg beider Parameter wurde als energiemangelbedingte Hyperketonämie (h-Ket) interpretiert. Ergebnisse: Die Ket- und h-Ket-Prävalenzen der laktierenden Milchkühe in 5 Jahren betrugen 19,3% und 10,0%. Ein jahreszeitlicher Effekt ließ sich nur für die Bili-Prävalenz bei laktierenden Milchkühen nachweisen, die im Herbst sank (p < 0,05). Bei Mutterkühen betrug die Ket- und h-Ket-Prävalenz im Beobachtungszeitraum 11,0% bzw. 9,1%. Schlussfolgerungen: Unter den Bedingungen der vorliegenden Studie lag kein fester jahreszeitlicher Effekt auf die Ketoserate von Kühen vor. Etwa die Hälfte der bei laktierenden Milchkühen auftretenden Hyperketonämien war durch Energiemangel bedingt, wobei die energetische Versorgung der Tiere im Herbst offenbar vergleichsweise gut war. In der Mutterkuhhaltung hat Ketose eine geringere Bedeutung, bei deut - lichem Überwiegen energiemangelbedingter Ereignisse. Klinische Relevanz: In der tierärztlichen Praxis sollten bei Verdacht auf subklinische Ketose bzw. bei Stichprobenuntersuchung zur Bestandsbetreuung neben BHB auch Parameter mit Bezug zum Energiehaushalt, zumindest auch Bilirubin im Blutserum, untersucht werden.

Abstract
Monozygotic (MZ) twins have been thought to be genetically identical. However, recent studies have shown discordant variants between them. We performed whole-exome sequencing (WES) in five MZ twin pairs with discordant neurodevelopmental disorders and one healthy control MZ twin to detect discordant variants. We identified three discordant variants confirmed by deep sequencing after analysis by personalized next-generation sequencing (NGS). Three mutations in FBXO38 (chr5:147774428;T>G), SMOC2 (chr6:169051385;A>G) and TDRP (chr8:442616;A>G), were detected with low allele frequency of mutant alleles on deep sequencing, suggesting that these loci are mosaic due to somatic mutations in a developmental stage. Our results suggest that deep sequencing analysis would be an adequate method to detect discordant mutations in candidate genes responsible for heritable diseases.

Abstract
Interferon Regulatory Factor 6 (IRF6) is a critical regulator of differentiation, proliferation, and migration of keratinocytes. Mutations in IRF6 cause two autosomal dominant disorders characterized by cleft lip with or without cleft palate. In addition, DNA variation in IRF6 confers significant risk for non-syndromic cleft lip and palate. IRF6 is also implicated in adult onset development and disease processes, including mammary gland development and squamous cell carcinoma. Mice homozygous for a null allele of Irf6 die shortly after birth due to severe skin, limb, and craniofacial defects, thus impeding the study of gene function after birth. To circumvent this, a conditional allele of Irf6 was generated. To validate the functionality of the conditional allele, we used three "deleter" Cre strains: Gdf9-Cre, CAG-Cre, and Ella-Cre. When Cre expression was driven by the Gdf9-Cre or CAG-Cre transgenes, 100% recombination was observed as indicated by DNA genotyping and phenotyping. In contrast, use of the Ella-Cre transgenic line resulted in incomplete recombination, despite expression at the one-cell stage. In sum, we generated a novel tool to delete Irf6 in a tissue specific fashion, allowing for study of gene function past perinatal stages. However, recombination efficiency of this allele was dictated by the Cre-driver used.

Abstract
It has been reported that tuberculosis (TB) worsens after cessation of tumor necrosis factor-α inhibitors and starting anti-TB treatment. Little is known about the immunological pathogenesis of this paradoxical response (PR). We report the first case of a TB patient in whom PR occurred concurrently with elevation of circulating tumor necrosis factor-α (TNFα) levels. A 75-year-old woman, who had been treated with adalimumab for SAPHO syndrome, developed disseminated TB. Soon after administration of anti-TB treatment (isoniazid, rifampicin, pyrazinamide, and ethambutol), and after discontinuation of adalimumab, a PR occurred. Serial testing of serum cytokine levels revealed a marked increase in TNFα, and a decline in interferon-γ levels. Despite intensive treatment with antibiotics, prednisolone, noradrenaline, and mechanical ventilation, acute respiratory distress syndrome developed and she died. Thus, overproduction of TNFα after cessation of TNFα inhibitors may partially account for the pathogenesis of a PR. This supports preventative or therapeutic reinitiation of TNFα inhibitors when PR occurs. Serial monitoring of circulating inflammatory cytokine levels could lead to earlier identification of a PR.

Abstract
Background The effectiveness of hepatoprotective drugs for DIH (drug induced hepatotoxicity) during tuberculosis treatment is not clear. We evaluated the effectiveness of hepatoprotective drugs by comparing the period until the normalization of hepatic enzymes between patients who were prescribed with the hepatoprotective drugs after DIH was occurred and patients who were not prescribed with the hepatoprotective drugs. Methods During 2006–2010, 389 patients with active tuberculosis were included in this study. DIH was defined as elevation of peak serum aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) of more than twice the upper limit of normal (ULN). We divided the patients into the severe (peak serum AST and/or ALT elevation of >5 times the ULN), moderate (peak serum AST and/or ALT elevation of >3 to ≤5 times the ULN), and mild DIH groups (peak serum AST and/or ALT elevation of >2 to ≤3 times the ULN). We compared the average period until the normalization of hepatic enzymes between patient subgroups with and without hepatoprotective drugs (ursodeoxycholic acid: UDCA, stronger neo-minophagen C: SNMC, and glycyrrhizin). Results In the severe group, there was no significant difference in the average period until the normalization between subgroups with and without hepatoprotective drugs (21.4 ± 10.8 vs 21.5 ± 11.1 days, P = 0.97). In the mild group, the period was longer in the subgroup with hepatoprotective drugs than that without hepatoprotective drugs (15.7 ± 6.2 vs 12.4 ± 7.9 days, P = 0.046). Conclusion Regardless of the severity, hepatoprotective drugs did not shorten the period until the normalization of hepatic enzymes.

Abstract
Neuroendocrine neoplasms (NENs) are derived from endocrine cells in various organs and share common morphological features. This study aimed to clarify whether NENs of different organs are comparable at the molecular pathologic level. We retrospectively collected 99 cases of NENs from gastro-entero-pancreatic, lung, and other organs and reclassified these according to identical criteria. Grade, site, and molecular expression profile including NE markers, Ki-67, p53, somatostatin receptor type 2A (SSTR2A), and phosphatase and tensin homolog (PTEN) were compared. PTEN immunoreactivity was also compared with genomic copy number by fluorescence in situ hybridization (FISH) and droplet digital polymerase chain reaction (ddPCR). No significant differences were observed in the immunoreactivities of NE markers, p53, SSTR2A, or PTEN expression in NENs between the different organ sites. PTEN and p53 functional inactivation along with the loss of membranous SSTR2A expression appeared to be commonly involved in high-grade NEN. FISH results were significantly correlated with the level of PTEN immunoreactivity and with the findings of ddPCR analyses. The demonstration that these tumors are comparable at the molecular level will likely contribute to the broadening of therapeutic options such as the use of somatostatin analogues and mTOR inhibitors against NENs regardless of the affected organ, whereas molecular characterization of tumor grade will be useful for determining treatment strategy.

Abstract
The relation between CA1 neurons, fimbria-fornix and cholinergic neurons of the basal forebrain was examined with the aid of Acetylcholine esterase (AChE) staining, Woelcke's staining and immunohistochemistry of Choline-acetyl transferase (ChAT). The transected side of the hippocampus was poorly stained by AChE two weeks after the transection, when the ipsilateral medial septum ChAT-positive neurons were reduced, but showed good recovery with AChE six weeks later. Nerve growth factor (NGF) was added at a dose of 10 micrograms/100 microliters immediately after the aspiration, and after that once per week with cisternal puncture. As a result, ipsilateral medial septum ChAT-positive neurons were preserved, but cross innervation with relation to hypertrophy of the cholinergic neurons was not detectable even six weeks after the transection. Furthermore, delayed CA1 neuronal death on the transected side of the hippocampus following occlusion of four vessels for 30 minutes was not detectable two weeks after the operation, although neuronal density was reduced after six weeks. The density of neurons on the transected side of the hippocampus in the CA1 subfield with treated NGF had not decreased significantly six weeks later. Therefore, we suspect that the input from cholinergic fibres must be transported to the hippocampal pyramidal neurons responding to NGF, and it was confirmed that cholinergic deafferentation prevents the delayed neuronal death of CA1 pyramidal neurons during transient ischaemia.

Abstract
In the rat model of middle cerebral artery (MCA) occlusion, axons originating from the ipsilateral cortical and thalamic neurons are injured by ischaemia. The cortical neurons survive thereafter without retrograde degeneration, but thalamic neurons slowly die because of retrograde degeneration. The fate of these two neurons is remarkably different and may be related to neurotrophic activity induced by ischaemia. We detected ischaemia-related neurotrophic activity, and partially purified the factor. Tissue samples were obtained from the cortex adjacent to the infarction and contralateral corresponding site at 4, 8 and 12 days after occlusion of the MCA. They were homogenated with a culture medium and ultracentrifuged. The supernatant was obtained and used for neurotrophic assay. Foetal cortical neurons were obtained from 17 days rat embryo and cultured. Neurotrophic activity was assayed by applying tissue extract to the culture medium. Application of periischaemic cortical extract obtained at 8 and 12 days after ischaemia improved neuronal survival by 50% and 200% as compared to contralateral cortical extract, respectively. The activity was not detectable at 4 days after ischaemia. The neurotrophic activity disappeared by heating the extract at 90 degrees C for 10 min. We fractionated the extract by saturated ammonium sulphate precipitation, followed by gel-filtered with Superose 12 column. The neurotrophic activity was detected in the precipitation of 30 to 60% saturation fraction of ammonium sulphate. With gel-filtration we separated neurotrophic activity in several fractions, which included marker proteins of 8, 22 and 30 kilodaltons. The activities were only detected in the lesioned side but not in the contralateral side.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
BACKGROUND We have previously reported a hybrid procedure that uses a combination of laparoscopic mobilization of the liver and subsequent hepatectomy under direct vision in living donor liver transplantation (LDLT). We present the details of this hybrid procedure and the outcomes of the procedure. METHODS Between January 1997 and August 2014, 204 LDLTs were performed at Nagasaki University Hospital. Among them, 67 recent donors underwent hybrid donor hepatectomy. Forty-one donors underwent left hemihepatectomy, 25 underwent right hemihepatectomy, and 1 underwent posterior sectionectomy. First, an 8-cm subxiphoid midline incision was made; laparoscopic mobilization of the liver was then achieved with a hand-assist through the midline incision under the pneumoperitoneum. Thereafter, the incision was extended up to 12 cm for the right lobe and posterior sector graft and 10 cm left lobe graft procurement. Under direct vision, parenchymal transection was performed by means of the liver-hanging maneuver. The hybrid procedure for LDLT recipients was indicated only for selected cases with atrophic liver cirrhosis without a history of upper abdominal surgery, significant retroperitoneal collateral vessels, or hypertrophic change of the liver (n = 29). For total hepatectomy and splenectomy, the midline incision was sufficiently extended. RESULTS All of the hybrid donor hepatectomies were completed without an extra subcostal incision. No significant differences were observed in the blood loss or length of the operation compared with conventional open procedures. All of the donors have returned to their preoperative activity level, with fewer wound-related complaints compared with those treated with the use of the conventional open procedure. In recipients treated with the hybrid procedure, no clinically relevant drawbacks were observed compared with the recipients treated with a regular Mercedes-Benz-type incision. CONCLUSIONS Our hybrid procedure was safely conducted with the same quality as the conventional open procedure in both LDLT donors and recipients.

Abstract
Camurati-Engelmann disease (CAEND, OMIM 131300) is a rare autosomal dominant, progressive diaphyseal dysplasia, which is characterized by hyperosteosis and sclerosis of the diaphyses of long bones. Estimated number of patients with CAEND in Japan is approximately 50-60 by our epidemiological survey. We have reported that domain-specific mutations in transforming growth factor-β1 gene(TGFB1) cause CAEND. Mutations in latency associated peptide(LAP) domain of TGF-β1 destabilize the complex and may hyperactivate TGF signal pathway. We tried to establish CAEND model mice by gene-targeting, but could not because of spermatogenesis defects in chimera mice. We also failed using CRISPR/Cas9 system. Alternatively, we established CAEND patient-derived iPS cells, and are advancing research with them to develop novel therapeutic agents for CAEND.
