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
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
Imprinted genes are differentially expressed in a parent-of-origin-specific manner. Parental origin of the alleles is discriminated by intragenic DNA polymorphisms. Comparisons of parental allelic expression have been analysed by semiquantitative RT-PCR. Here, we developed a novel quantitative method for allelic expression of the imprinted gene Ube3a, which inactivation and mutations cause Angelman syndrome and predominantly expressed by the maternal allele in neuronal tissues. In this method, cDNA was amplified by droplet digital PCR (ddPCR) coupled with allele-specific locked nucleic acid (LNA) TaqMan probes, which labelled by FAM and HEX were designed to detect the SNPs in the target regions. ddPCR assay demonstrated that the sense transcript of Ube3a was equally expressed from both parental alleles in adult tissues except neuronal tissues, where Ube3a expression from the paternal allele was about 10 to 14% of total Ube3a expression in adult brain, and 20% in spinal cord. The antisense transcript of Ube3a was expressed at 60% to 70% of the sense transcript of Ube3a in adult brain. Changes in the Ube3a transcripts during postnatal brain development were also evaluated by ddPCR. The ddPCR method is far more reliable and simpler to use than semiquantitative PCR to analyse skewed or faint allelic expression of imprinted genes.

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
Necdin (Ndn) transgenic (Tg) mice were generated with a bacterial artificial chromosome (BAC) clone. Droplet digital PCR (ddPCR) and inverse PCR methods revealed that the transgene consisted of four fragments with a total length of 171 kb. Two of these fragments were tandem tail-to-tail duplicates of 77 kb and 37 kb that both contained a Ndn gene. The transgene was inserted in chromosome 15qD1. Ndn is a paternally expressed imprinted gene; however, the total expression level of Ndn in hemizygous Tg mice was approximately twofold higher than that in wild-type mice. ddPCR assays with locked nucleic acid (LNA) TaqMan probes revealed that transgenic Ndn expression was almost equal to endogenous Ndn expression, despite there being two copies of the Ndn gene in the transgene, indicating an interaction between the transcriptional regulation of endogenous Ndn and the transgene. ddPCR assays with LNA TaqMan probes were also applied for imprinting analysis to confirm exclusive paternal expression in tissues with low Ndn expression. This is the first report of a Tg mouse with a tandem duplication of a Ndn transgene and Ndn overexpression, which will be useful for the in vivo study of Ndn overexpression and for rescue experiments of the neonatal lethality seen in the Ndn knockout mouse.

Abstract
Angelman syndrome (AS) is a genetic neurodevelopmental disorder in which cerebellar functioning impairment has been documented despite the absence of gross structural abnormalities. Characteristically, a spontaneous 160 Hz oscillation emerges in the Purkinje cells network of the Ube3a (m-/p+) Angelman mouse model. This abnormal oscillation is induced by enhanced Purkinje cell rhythmicity and hypersynchrony along the parallel fiber beam. We present a pathophysiological hypothesis for the neurophysiology underlying major aspects of the clinical phenotype of AS, including cognitive, language and motor deficits, involving long-range connection between the cerebellar and the cortical networks. This hypothesis states that the alteration of the cerebellar rhythmic activity impinges cerebellar long-term depression (LTD) plasticity, which in turn alters the LTD plasticity in the cerebral cortex. This hypothesis was based on preliminary experiments using electrical stimulation of the whiskers pad performed in alert mice showing that after a 8 Hz LTD-inducing protocol, the cerebellar LTD accompanied by a delayed response in the wild type (WT) mice is missing in Ube3a (m-/p+) mice and that the LTD induced in the barrel cortex following the same peripheral stimulation in wild mice is reversed into a LTP in the Ube3a (m-/p+) mice. The control exerted by the cerebellum on the excitation vs. inhibition balance in the cerebral cortex and possible role played by the timing plasticity of the Purkinje cell LTD on the spike-timing dependent plasticity (STDP) of the pyramidal neurons are discussed in the context of the present hypothesis.

Abstract
The mouse chromosome 7C, orthologous to the human 15q11-q13 has an imprinted domain, where most of the genes are expressed only from the paternal allele. The imprinted domain contains paternally expressed genes, Snurf/Snrpn, Ndn, Magel2, Mkrn3, and Frat3, C/D-box small nucleolar RNAs (snoRNAs), and the maternally expressed gene, Ube3a. Imprinted expression in this large (approximately 3-4 Mb) domain is coordinated by a bipartite cis-acting imprinting center (IC), located upstream of the Snurf/Snrpn gene. The molecular mechanism how IC regulates gene expression of the whole domain remains partially understood. Here we analyzed the relationship between imprinted gene expression and DNA methylation in the mouse chromosome 7C using DNA methyltransferase 1 (DNMT1)-null mutant embryos carrying Dnmt1(ps) alleles, which show global loss of DNA methylation and embryonic lethality. In the DNMT1-null embryos at embryonic day 9.5, the paternally expressed genes were biallelically expressed. Bisulfite DNA methylation analysis revealed loss of methylation on the maternal allele in the promoter regions of the genes. These results demonstrate that DNMT1 is necessary for monoallelic expression of the imprinted genes in the chromosome 7C domain, suggesting that DNA methylation in the secondary differentially methylated regions (DMRs), which are acquired during development serves primarily to control the imprinted expression from the maternal allele in the mouse chromosome 7C.

Abstract
Angelman syndrome is a neurodevelopmental disorder caused by loss of function of the UBE3A gene encoding a ubiquitin E3 ligase. Motor dysfunction is a characteristic feature of Angelman syndrome, but neither the mechanisms of action nor effective therapeutic strategies have yet been elucidated. We report that tonic inhibition is specifically decreased in cerebellar granule cells of Ube3a-deficient mice, a model of Angelman syndrome. As a mechanism underlying this decrease in tonic inhibition, we show that Ube3a controls degradation of γ-aminobutyric acid (GABA) transporter 1 (GAT1) and that deficiency of Ube3a induces a surplus of GAT1 that results in a decrease in GABA concentrations in the extrasynaptic space. Administering low doses of 4,5,6,7-tetrahydroisothiazolo-[5,4-c]pyridin-3-ol (THIP), a selective extrasynaptic GABA(A) receptor agonist, improves the abnormal firing properties of a population of Purkinje cells in cerebellar brain slices and reduces cerebellar ataxia in Ube3a-deficient mice in vivo. These results suggest that pharmacologically increasing tonic inhibition may be a useful strategy for alleviating motor dysfunction in Angelman syndrome.

Abstract
Hereditary congenital ptosis (PTOS) is defined as drooping of the upper eyelid without any other accompanying symptoms and distinguished from syndromic blepharoptosis. Two previous linkage analyses assigned a PTOS locus (PTOS1) to 1p32-p34.1 and another (PTOS2) to Xq24-q27.1. In addition, in a sporadic case with a balanced chromosomal translocation t(1;8) (p34.3;q21.12), the ZFHX4 (zinc finger homeodomain 4) gene was found to be disrupted at the 8q21.12 breakpoint, but there was no gene at the 1p34.3 breakpoint, suggesting the existence of the third PTOS locus (PTOS1) at 8q21.12. We carried out a genome-wide linkage analysis in a Japanese PTOS family and calculated two-point and multipoint log of odds (LOD) scores with reduced penetrance. Haplotype analysis gave three candidate disease-responsible regions, i.e., 8q21.11-q22.1, 12q24.32-q24.33, and 14q21.1-q23.2. Although the family size is too small to define one of them, 8q21.11-q22.1 is a likely candidate region, because it contains the previously reported translocation breakpoint above. We thus performed mutation, Southern-blot and methylation analyses of ZFHX4 but could not find any disease-specific change in the family. Nevertheless, our data may support the localization of PTOS1.

Abstract
Congenital arhinia, complete absence of the nose, is an extremely rare anomaly with unknown cause. To our knowledge, a total of 36 cases have been reported, but there has been no molecular-genetic study on this anomaly. We encountered a sporadic case of congenital arhinia associated with a de novo chromosomal translocation, t(3;12)(q13.2;p11.2). This led us to analyze the patient by BAC-based FISH for translocation breakpoints and whole-genome array CGH for other possible deletions/duplications in the genome. We found in this patient an approximately 19 Mb deletion spanning from 3q11.2 to 3q13.31 but no disruption of any gene(s) at the other breakpoint, 12p11.2. As the deleted segment at 3q was a strong candidate region containing the putative arhinia gene, we also performed the array CGH in four other arhinia patients with normal karyotypes, as well as mutation analysis of two genes, COL8A1 and CPOX, selected among hundreds of genes located to the deleted region, because they are expressed during early stages of human craniofacial development. However, in the four patients, there were no copy number aberrations in the region examined or no mutations in the two genes. Although our study failed to identify the putative arhinia gene, the data may become a clue to unravel the underlying mechanism of arhinia.

Abstract
Mouse Grb10 is a tissue-specific imprinted gene with promoter-specific expression. In most tissues, Grb10 is expressed exclusively from the major-type promoter of the maternal allele, whereas in the brain, it is expressed predominantly from the brain type promoter of the paternal allele. Such reciprocally imprinted expression in the brain and other tissues is thought to be regulated by DNA methylation and the Polycomb group (PcG) protein Eed. To investigate how DNA methylation and chromatin remodeling by PcG proteins coordinate tissue-specific imprinting of Grb10, we analyzed epigenetic modifications associated with Grb10 expression in cultured brain cells. Reverse transcriptase PCR analysis revealed that the imprinted paternal expression of Grb10 in the brain implied neuron-specific and developmental stage-specific expression from the paternal brain type promoter, whereas in glial cells and fibroblasts, Grb10 was reciprocally expressed from the maternal major-type promoter. The cell-specific imprinted expression was not directly related to allele-specific DNA methylation in the promoters because the major-type promoter remained biallelically hypomethylated regardless of its activity, whereas gametic DNA methylation in the brain type promoter was maintained during differentiation. Histone modification analysis showed that allelic methylation of histone H3 lysine 4 and H3 lysine 9 were associated with gametic DNA methylation in the brain type promoter, whereas that of H3 lysine 27 regulated by the Eed PcG complex was detected in the paternal major-type promoter, corresponding to its allele-specific silencing. Here, we propose a molecular model that gametic DNA methylation and chromatin remodeling by PcG proteins during cell differentiation cause tissue-specific imprinting in embryonic tissues.

Abstract
Array using 2,173 BAC clones covering the whole human genome has been constructed. All clones spotted were confirmed to show a unique signal at the predicted chromosomal location by FISH analysis in our laboratory. A total of 30 individuals with idiopathic mental retardation (MR) were analyzed by comparative genomic hybridization using this array. Three deletions, one duplication, and one unbalanced translocation could be detected in five patients, which are likely to contribute to MR. The constructed array was shown to be an efficient tool for the detection of pathogenic genomic rearrangements in MR patients as well as copy number polymorphisms (CPNs).

Abstract
Although most imprinted genes display parent-origin-specific gene expression in tissues where they are transcribed, some genes are imprinted in a tissue-specific manner. Genes that show brain-specific imprinting or brain-specific lack of imprinting present a unique opportunity to study the process of imprinting during tissue differentiation. In this review, I introduce the systematic study of brain-cell-lineage-specific imprinting using a primary brain cell culture system, where neurons or glial cells are cultured separately. Two reports using the primary brain cell culture revealed brain-cell-lineage-specific imprinting in Ube3a and Igf2r, which had previously been described to show brain-specific imprinting and brain-specific lack of imprinting, respectively. Such brain-cell-lineage-specific imprinting was associated with cell-specific epigenetic modifications, especially with their reciprocally imprinted antisense non-coding RNAs, Ube3a-ATS and Air. These results emphasize the necessity of imprinting analysis at the cell level rather than in whole brain tissue during brain differentiation. The brain cell culture system provides us with a new powerful tool to understand the molecular mechanism of brain-specific imprinting.

Abstract
The human chromosome 15q11-q13, or mouse chromosome 7C, is an imprinting domain controlled by bipartite imprinting centers (ICs): Prader-Willi syndrome (PWS)-IC and Angelman syndrome (AS)-IC. PWS-IC functions to maintain the paternal epigenotype on the paternal chromosome in somatic cells, while AS-IC plays a role in the establishment of the maternal epigenetic mark at PWS-IC in the female germline or early embryos. Several alternative exons and promoters of Snurf-Snrpn (SNRPN upstream reading frame-small nuclear ribonucleoprotein polypeptide N) are expressed as "IC transcripts". Previous studies have shown that IC-transcript expression is restricted to the brain. We studied expression of the mouse IC-transcript in tissues including brain and oocytes as well as in cultured neurons and glia cells by RT-PCR and by in situ hybridization (ISH) in oocytes. The IC transcript was strongly expressed in brain (especially in neurons) and ovary (especially in oocytes and granulosa cells), while no expression was found in other tissues. This was confirmed by quantitative analysis and ISH. Expression levels in the brain were 7-fold higher compared to those in ovaries. ISH signals were observed in oocytes and granulosa cells of the secondary and developing follicles. These findings, together with previous data, suggest that the IC transcript may be associated with the establishment of PWS-IC methylation on the maternal chromosome as an AS-IC cis-acting element.

Abstract
The prevalence of nonsyndromic cleft lip with or without cleft palate (CL/P) and cleft palate only (CPO) are believed to be higher in the Japanese than in Americans, Europeans or Africans. The purpose of this study was to investigate, in a Japanese population, relationships between CL/P or CPO and seven candidate genes (TGFB3, DLX3, PAX9, CLPTM1, TBX10, PVRL1, TBX22) that showed positive associations in other populations and are expressed in the oral/lip region in developing mice. We first searched for mutations in these genes among 112 CL/P and 16 CPO patients, and found a heterozygous missense mutation (640A > G, S214G) in exon 3 of PAX9 in two sibs with CL/P and their phenotypically normal mother from a Japanese family. A population-based case-control analysis and a family-based transmission disequilibrium test (TDT), using single nucleotide polymorphisms (SNPs), and two-SNP haplotypes of the genes, between the 112 CL/P cases with their parents and 192 controls indicated a significant association at one SNP site, IVS1 + 5321, in TGFB3 with a P-value of 0.0016. Population-based haplotyping revealed that the association was most significant for haplotype "A/A" consisting of IVS1 + 5321 and IVS1 - 1572; TDT also gave a P-value of 0.0252 in this haplotype.

Abstract
A 36-week-old fetus was referred to the medical center because of his cystic mass and fluid in left thoracic cavity, and was delivered by cesarean section to manage neonatal problems at 37 weeks of gestation. Emergent surgical repair of the left diaphragmatic hernia was performed, but severe hypoxia persisted, and he expired on the following day. Chromosome analysis of cultured amniotic fluid cells indicated 46,XY,del(8)(p23.1p23.1). This is the fourth case of 8p23.1 deletion associated with diaphragmatic hernia. Microarray comparative genomic hybridization analysis using DNA of cultured amniotic fluid cells showed that six clones were deleted, which were mapped to the region between two low copy repeats (LCRs) at 8p23.1 previously described. Microsatellite analysis revealed that the deletion was of paternal origin, and his parents did not carry 8p23.1 polymorphic inversion. These data strongly suggested that the 8p23.1 interstitial deletion should have arisen through a different mechanism from that of inv dup del(8p) whose structural abnormality is always of maternal origin and accompanies heterozygous 8p23.1 polymorphic inversion in mother.

Abstract
The mouse insulin-like growth factor II receptor (Igf2r) gene and its antisense transcript Air are reciprocally imprinted in most tissues, but in the brain, Igf2r is biallelically expressed despite the imprinted Air expression. To investigate the molecular mechanisms of such brain-specific relaxation of Igf2r imprinting, we analyzed its expression and epigenetic modifications in neurons, glial cells and fibroblasts by the use of primary cortical cell cultures. In glial cells and fibroblasts, Igf2r was maternally expressed and Air was paternally expressed, whereas in the primary cultured neurons, Igf2r was biallelically expressed and Air was not expressed. In the differentially methylated region 2 (DMR2), which includes the Air promoter, allele-specific DNA methylation, differential H3 and H4 acetylation and H3K4 and K9 di-methylation were maintained in each cultured cell type. In DMR1, which includes the Igf2r promoter, maternal-allele-specific DNA hypomethylation, histones H3 and H4 acetylation and H3K4 di-methylation were apparent in glial cells and fibroblasts. However, in neurons, biallelic DNA hypomethylation and biallelic histones H3 and H4 acetylation and H3K4 di-methylation were detected. These data indicate that lack of reciprocal imprinting of Igf2r and Air in the brain results from neuron-specific relaxation of Igf2r imprinting associated with neuron-specific histone modifications in DMR1 and lack of Air expression. Our observation of biallelic Igf2r expression with no Air expression in neurons sheds light on the function of Air as a critical effector in Igf2r silencing and suggests that neuron-specific epigenetic modifications related to the lineage determination of neural stem cells play a critical role in controlling imprinting by antisense transcripts.

Abstract
We analyzed five patients with inverted duplication deletion of 8p [inv dup del(8p)] using fluorescence in situ hybridization (FISH) and short tandem repeat polymorphism (STRP) analysis. In all patients, inv dup del(8p) consisted of a deleted distal segment, an intact in-between segment, and a duplicated proximal segment. In all of them, the proximal breakpoint of the deletion and one of the breakpoints of the duplication were identical, each located at one of the two olfactory receptor gene clusters at 8p23. FISH analysis showed all their mothers to be heterozygous carriers of an 8p23 inversion [inv(8)(p23)]. STRP analysis indicated that the deletions occurred in maternally derived chromosomes. The duplicated segments had two copies of maternal, either heterozygous or homozygous alleles. These findings support and reinforce those in 16 patients with inv dup del(8p) and their parents by Floridia et al. [1996: Am J Hum Genet 58:785-796] and subsequent additional studies of 10 of them by Giglio et al. [2001: Am J Hum Genet 68:874-883]. Based on these findings, we propose a model for the inv dup del(8p) formation. The inverted segment and its normal counterpart in inv(8)(p23) heterozygous carrier mothers form a loop at the pachytene period of meiosis I. Inv dup del(8p) with heterozygous duplication is formed through at least one meiotic recombination within the loop. Inv dup del(8p) with the homozygous duplication arises through two meiotic recombinations on the inv(8)(p23) chromosome (one within the loop and the other between the loop and centromere). Subsequent rescue by eliminating a part of the duplicated segment and a centromere enables formation of viable inv dup del(8p). The frequency of the inv(8)(p23) allele is 39% in a normal Japanese population, comparable to 26% in Europeans Giglio et al. [2001: Am J Hum Genet 68:874-883]. The proposed mechanism of formation of inv dup del(8p) requires two independent events (a recombination within the loop and subsequent rescue), which may explain its rarity.

Abstract
Proximal 12q deletion is a very rare chromosomal abnormality. Only five cases have been reported. Among the five, an Argentinian patient (Case 1) with del(12)(q11q13) and a Japanese patient (Case 2) with del(12)(q12q13.12) were analyzed because they shared several clinical features: growth and psychomotor developmental delay; strabismus; broad and short nose with anteverted nostrils; high, arched palate; large, lowset ears; widely set nipples; short fingers and clinodactyly of fifth fingers; and abnormality of the second and third toes. To clarify the correlation between the deleted genes and their phenotypes, we delimited their deleted regions by fluorescence in situ hybridization (FISH). The overlapped region in the deletions spanned 6.2 Mb where at least 15 genes were predicted to localize on the current human genome database. Among them, YAF2 and AMIGO2 were the most plausible candidates to affect growth and psychomotor retardation, respectively, in both cases. Regarding unique symptoms in each case, congenital fibrosis of the extraocular muscles found only in Case 1 may be caused by KIF21A deletion and hearing loss and cleft palate in Case 2 by COL2A1 defect.

Abstract
Patients with 9q34.3 terminal deletion usually show a clinically recognizable phenotype characterized by specific facial features (microcephaly, flat face, arched eyebrows, hypertelorism, short nose, anteverted nostrils, carp mouth and protruding tongue) in combination with severe mental retardation, hypotonia, and other anomalies. We analyzed six unrelated patients with a various 9q34.3 terminal deletion. While having different-sized 9q34.3 deletions, all of these patients shared several distinctive anomalies. These anomalies are likely to arise from a commonly deleted region at distal 9q34.3. Fluorescence in situ hybridization (FISH) analysis using a dozen BAC clones mapped at the 9q34.13-q34.3 region defined the shortest region of deletion overlap (SRO) as a 1-Mb segment proximal to 9qter containing eight known genes. Possible candidate genes delineating specific phenotypes of the 9q34.3 terminal deletion syndrome are discussed.

Abstract
Marfan syndrome is an extracellular matrix disorder with cardinal manifestations in the eye, skeleton and cardiovascular systems associated with defects in the gene encoding fibrillin (FBN1) at 15q21.1 (ref. 1). A second type of the disorder (Marfan syndrome type 2; OMIM 154705) is associated with a second locus, MFS2, at 3p25-p24.2 in a large French family (family MS1). Identification of a 3p24.1 chromosomal breakpoint disrupting the gene encoding TGF-beta receptor 2 (TGFBR2) in a Japanese individual with Marfan syndrome led us to consider TGFBR2 as the gene underlying association with Marfan syndrome at the MSF2 locus. The mutation 1524G-->A in TGFBR2 (causing the synonymous amino acid substitution Q508Q) resulted in abnormal splicing and segregated with MFS2 in family MS1. We identified three other missense mutations in four unrelated probands, which led to loss of function of TGF-beta signaling activity on extracellular matrix formation. These results show that heterozygous mutations in TGFBR2, a putative tumor-suppressor gene implicated in several malignancies, are also associated with inherited connective-tissue disorders.

Abstract
Type 2 diabetes mellitus (T2DM) is a group of multifactorial disorders due to either defective insulin secretion or action. Despite the fact that numerous genetic researches of T2DM have been pursued, the pathogenic mechanisms remain obscure. We encountered a T2DM family associated with a balanced reciprocal translocation, t(3;9)(p21.31;q33.1). To isolate a candidate gene susceptible to T2DM, we constructed physical maps covering both the 3p and 9q breakpoints of the translocation in the family. Consequently, the inositol hexaphosphate kinase 1 gene ( IHPK1) (OMIM *606991) was found to be disrupted at the 3p21.31 breakpoint. We then carried out sequence analysis for all coding regions of IHPK1 in 405 unrelated T2DM patients in order to validate whether aberrations of the gene are common in T2DM patients, but we failed to detect any pathogenic changes. The disruption of IHPK1 or another predisposing gene affected by position effect of the translocation may explain the T2DM phenotype at least in this family. Alternatively, the IHPK1 disruption in the family is a chance association.

Abstract
MEST is one of the imprinted genes in human. With the assistance of our integration map and the complete sequence in the registry, we mapped a total of 16 genes/transcripts at the 1.5-Mb MEST-flanking region at 7q32. This region has been suggested to form an imprinted gene cluster, because MEST and its three flanking genes/transcripts (MESTIT1, CPA4, and COPG2IT1) were reported to be imprinted, although two (TSGA14 and COPG2) were shown to escape imprinting. In this study, 10 other genes/transcripts were examined for their imprinting status in human fetal tissues. The results indicated that 8 genes/transcripts (NRF1, UBE2H, HSPC216, KIAA0265, FLJ14803, CPA2, CPA1, and DKFZp667F0312) were expressed biallelically. The imprinting status of two (TSGA13 and CPA5) was not conclusive, because of their weak and/or tissue-specific expression and inconstant results. These findings provided evidence that only 4 of the 16 genes/transcripts located to the region show monoallelic expression, while others are not involved in imprinting. Therefore, it is less likely that the MEST-flanking 7q32 region forms a large imprinted domain.

Abstract
Osteoporosis is a multifactorial trait with low bone mineral density (BMD). We report results of an association study between BMD and nine candidate genes ( TGFB1, TGFBR2, SMAD2, SMAD3, SMAD4, IFNB1, IFNAR1, FOS and LRP5), as well as of a case-control study of osteoporosis. Samples for the former association study included 481 general Japanese women. Among the nine candidate genes examined, only LRP5 showed a significant association with BMD. We identified a strong linkage disequilibrium (LD) block within LRP5. Of five LPR5 single nucleotide polymorphisms (SNPs) that are located in the LD block, three gave relatively significant results: Women with the C/C genotype at the c.2220C>T SNP site had higher adjusted BMD (AdjBMD) value compared to those with C/T and T/T (p=0.022); and likewise, G/G at IVS17-30G>A and C/C women at c.3989C>T showed higher AdjBMD than those with G/A or A/A (p=0.039) and with C/T or T/T ( p=0.053), respectively. The case-control study in another series of samples consisting of 126 osteoporotic patients and 131 normal controls also gave a significant difference in allele frequency at c.2220C>T (kappa2=6.737, p=0.009). These results suggest that LRP5 is a BMD determinant and also contributes to a risk of osteoporosis.

Abstract
Sotos syndrome (SoS) is an autosomal dominant overgrowth syndrome with characteristic craniofacial dysmorphic features and various degrees of mental retardation. We previously showed that haploinsufficiency of the NSD1 gene is the major cause of SoS, and submicroscopic deletions at 5q35, including NSD1, were found in about a half (20/42) of our patients examined. Since the first report, an additional 70 SoS cases consisting of 53 Japanese and 17 non-Japanese have been analyzed. We found 50 microdeletions (45%) and 16 point mutations (14%) among all the 112 cases. A large difference in the frequency of microdeletions between Japanese and non-Japanese patients was noted: 49 (52%) of the 95 Japanese patients and only one (6%) of the 17 non-Japanese had microdeletions. A sequence-based physical map was constructed to characterize the microdeletions. Most of the microdeletions were confirmed to be identical by FISH analysis. We identified highly homologous sequences, i.e., possible low copy repeats (LCRs), in regions flanking proximal and distal breakpoints of the common deletion, This suggests that LCRs may mediate the deletion. Such LCRs seem to be present in different populations. Thus the different frequency of microdeletions between Japanese and non-Japanese cases in our study may have been caused by patient-selection bias.

Abstract
To characterize a submicroscopic, common 8p23 polymorphic inversion, we constructed a complete BAC/PAC-based physical map covering the entire 4.7-Mb inversion and its flanking regions. Two low-copy repeats (LCRs), REPD (approximately 1.3 Mb) and REPP (approximately 0.4 Mb), were identified at each of the inversion breakpoints. Comparison of the REPD and REPP sequences revealed that REPD showed high homology to REPP, with complex direct and inverted orientations. REPD and REPP contain six and five olfactory receptor gene-related sequences, respectively. LCRs at 8p23 showed multiple FISH signals from an Old World monkey to the human. Thus, multiplication of the LCR may have occurred at least 21-25 million years ago. We also investigated the frequency of the 4.7-Mb inversion in the general Japanese population and found that the allele frequency for the 8p23 inversion was estimated to be 27%.

Abstract
An 8-year-old girl with a combination of clinical manifestations of partial duplication 4p and the Wolf-Hirschhorn syndrome was studied. Chromosomal G-banding and FISH analyses showed a 33.2-Mb segment of inverted duplication at 4p14-p16.3 and a 2.8-Mb segment of deletion at 4p16.3-pter (including the Wolf-Hirschhorn syndrome critical region). The chromosomes of the parents were normal. Her karyotype was thus 46,XX, inv dup del(4)(:p14 --> p16.3::p16.3 --> qter) de novo. The inverted duplication deletion was assumed to have arisen through chromatid breakage at 4p16.3, U-type reunion at the breakpoints to produce a dicentric intermediate, breakage of the dicentric to result in a monocentric, and telomere capture/healing of the broken end. Olfactory receptor gene clusters at 4p16.3 were ruled out as an intermediary of the duplication deletion process.

Abstract
The mouse Atp10a gene is located at the border of an imprinted domain distal to the p-locus on mouse chromosome 7. The localization of Atp10a neighboring the maternally expressed gene Ube3a in the imprinted domain and an unusual inheritance pattern of the obesity phenotype with a p-locus deletion have suggested that Atp10a might be imprinted and associated with body fat. Recently, its human ortholog, ATP10A, was identified as the second imprinted gene with maternal expression in the human chromosome 15q11-q13 imprinted domain. To elucidate the imprinting status of Atp10a, we performed expression analysis in various tissues from reciprocal crosses between C57BL/6 and PWK (divergent strains of Mus musculus) mice. The results revealed that Atp10a was biallelically expressed in all tissues examined. Furthermore, there was no differential methylation in the CpG island and no antisense transcripts of the gene. These findings suggest that the mouse Atp10a gene escapes genomic imprinting.

Abstract
Sotos syndrome (SoS) is characterized by pre- and postnatal overgrowth with advanced bone age; a dysmorphic face with macrocephaly and pointed chin; large hands and feet; mental retardation; and possible susceptibility to tumors. It has been shown that the major cause of SoS is haploinsufficiency of the NSD1 gene at 5q35, because the majority of patients had either a common microdeletion including NSD1 or a truncated type of point mutation in NSD1. In the present study, we traced the parental origin of the microdeletions in 26 patients with SoS by the use of 16 microsatellite markers at or flanking the commonly deleted region. Deletions in 18 of the 20 informative cases occurred in the paternally derived chromosome 5, whereas those in the maternally derived chromosome were found in only two cases. Haplotyping analysis of the marker loci revealed that the paternal deletion in five of seven informative cases and the maternal deletion in one case arose through an intrachromosomal rearrangement, and two other cases of the paternal deletion involved an interchromosomal event, suggesting that the common microdeletion observed in SoS did not occur through a uniform mechanism but preferentially arose prezygotically.

Abstract
The human UBE3A gene shows brain-specific partial imprinting, and lack of a maternally inherited allele causes Angelman syndrome (AS), which is characterized by neurobehavioral anomalies. In several AS model mice, imprinted Ube3a expression is detected predominantly in the hippocampus, cerebellar Purkinje cells and the olfactory bulb. Therefore, imprinting of mouse Ube3a is thought to be region-specific with different levels of silencing of the paternal Ube3a allele in different brain regions. To determine cell types of imprinted Ube3a expression, we analyzed its imprinting status in embryonic brain cells by using primary cortical cell cultures. RT-PCR and immunofluorescence were performed to determine the allelic expression of the gene. The Ube3a gene encodes two RNA transcripts in the brain, sense and antisense. The sense transcript was expressed maternally in neurons but biallelically in glial cells in the embryonic brain, whereas the antisense transcript was expressed only in neurons and only from the paternal allele. Our data present evidence of brain cell type-specific imprinting, i.e. neuron-specific imprinting of Ube3a in primary brain cell cultures. Reciprocal imprinting of sense and antisense transcripts present only in neurons suggests that the neuron-specific imprinting mechanism is related to the lineage determination of neural stem cells.

Abstract
By a search for novel human imprinted genes in the vicinity of the imprinted gene MEST, at chromosome 7q32, we identified the carboxypeptidase A4 gene ( CPA4) in a gene cluster of the carboxypeptidase family, 200 kb centromeric to MEST. Because CPA4 was originally identified as a protein induced in a prostate cancer cell line (PC-3) by histone deacetylase inhibitors, and was located at the putative prostate cancer-aggressiveness locus at 7q32, we investigated its imprinting status in fetal tissues and in adult benign hypertrophic prostate (BPH). RT-PCR using four intragenic polymorphisms as markers showed that CPA4 was expressed preferentially from the maternal allele in the fetal heart, lung, liver, intestine, kidney, adrenal gland, and spleen, but not in the fetal brain. It was also preferentially expressed in the BPH. These findings support that CPA4 is imprinted and may become a strong candidate gene for prostate cancer-aggressiveness. As a Silver-Russell syndrome (SRS) locus has been proposed to be located to a region near MEST and to be involved in imprinting, CPA4 would have been a candidate gene for SRS. However, analysis of ten SRS patients revealed no mutations in CPA4.

Abstract
We isolated a candidate choriocarcinoma suppressor gene from a PCR-based subtracted fragmentary cDNA library between normal placental villi and the choriocarcinoma cell line CC1. This gene comprises an open reading frame of 219 nt encoding 73 amino acids and contains a homeodomain as a consensus motif. This gene, designated NECC1 (not expressed in choriocarcinoma clone 1), is located on human chromosome 4q11-q12. NECC1 expression is ubiquitous in the brain, placenta, lung, smooth muscle, uterus, bladder, kidney, and spleen. Normal placental villi expressed NECC1, but all choriocarcinoma cell lines examined and most of the surgically removed choriocarcinoma tissue samples failed to express it. We transfected this gene into choriocarcinoma cell lines and observed remarkable alterations in cell morphology and suppression of in vivo tumorigenesis. Induction of CSH1 (chorionic somatomammotropin hormone 1) by NECC1 expression suggested differentiation of choriocarcinoma cells to syncytiotrophoblasts. Our results suggest that loss of NECC1 expression is involved in malignant conversion of placental trophoblasts.

Abstract
Transforming growth factor-beta1 (TGF-beta1) is a multifunctional cytokine that is produced in the platelet, bone, placenta, and other tissues. It acts as a growth inhibitor in many types of cells, and also mediates extracellular matrix production and immunosuppression. Mutations in the specific domain of its gene ( TGFB1) cause Camurati-Engelmann disease, a bone-sclerosing disorder, and those in other domains may be associated with osteoporosis. We identified 106 single-nucleotide polymorphisms and 11 other types of variations in TGFB1and six other genes. These genes were TGF-beta type I receptor gene (TGFBR1), TGF-beta type II receptor gene (TGFBR2), SMAD2 gene (SMAD2), SMAD3 gene (SMAD3), SMAD4 gene (SMAD4), and SMAD7 gene (SMAD7), all of which compose the TGF-beta1 signaling pathway. We also estimated allele frequencies of these DNA polymorphisms among 48 Japanese individuals. Our data will provide a useful resource for the study of disease susceptibility.

Abstract
Mirror-image polydactyly of hands and feet (MIP) is a very rare congenital anomaly characterized by mirror-image duplication of digits. To isolate the gene responsible for MIP, we performed translocation breakpoint cloning from an MIP patient with t(2;14)(p23.3;q13). We isolated a good candidate gene for MIP that was disrupted by the translocation of the patient. We had previously con structed a 1.2-megabase bacterial artificial chromosome (BAC)/P1-derived artificial chromosome (PAC) contig covering the 14q13 breakpoint of t(2;14)(p23.3;q13). From a 500-kb segment consisting of seven BAC/PAC clones in the contig, we isolated a novel gene (the mirror-image polydactyly 1 gene, designated as MIPOL1, GenBank Accession No. AY059470), in addition to the hepatocyte nuclear factor 3 alpha gene (HNF3A, GenBank Accession No. XM 007360). MIPOL1 spans about 350kb, comprises 15 exons, and encodes 442 amino acids. Northern blot analysis revealed that MIPOL1 expression is definite but very weak in adult heart, liver, skeletal muscle, kidney, and pancreas, and in fetal kidney. In view of the genome sequence and the contig map constructed, the 14q13 breakpoint of the patient was identified as located in intron 11 of MIPOL1, indicating that the gene was disrupted by the translocation, and that the breakage resulted in MIPOL1 protein truncation. Whole-mount in situ hybridization in mouse resulted in mouse Mipol1 signals all over E10.5-E13.5 mouse embryos. Two other unrelated patients with limb anomalies similar to MIP were subjected to mutation analysis of MIPOL1, but none had any mutations. We then isolated BAC clones from the other breakpoint, 2p23.3. A search for genes and expressed sequence tags in a more than 300-kb region around the 2p23.3 breakpoint found only the neuroblastoma-amplified protein gene (NAG, GenBank Accession No. NM 015909), which is located at least 50kb centromeric to the breakpoint and is not likely to be related to MIP. MIPOL1 is a good candidate gene for the MIP type of anomaly.

Abstract
Nonsyndromic low-frequency sensorineural hearing loss (LFSNHL) comprises a group (DFNA1, DFNA6, DFNA14, and DFNA38) of hearing disorders affecting only frequencies below 2000 Hz, and is often associated with tinnitus. An LFSNHL locus has recently been assigned to chromosome 4p16, and mutations in WFS1, the causative gene for Wolfram syndrome, have been found to cause LFSNHL in families with DFNA6, DFNA14, or DFNA38. We performed a genome-wide linkage analysis of a Japanese family in which 20 members were affected with LFSNHL and obtained a maximum LOD score of 5.36 at a recombination fraction of 0.05 ( P = 1.00) at the D4S2983 locus on 4p16. Haplotype analysis revealed that the disease locus mapped to between D4S2366 and D4S2983. Mutation analysis revealed a novel missense mutation (K634T) in WFS1. We thus concluded that the LFSNHL in this family was caused by the WFS1 mutation. The mutation observed (K634T) was located in the hydrophobic, extracytoplasmic, juxta-transmembrane region of the WFS1 protein, wolframin, and was hitherto undescribed. This unique mutation site in our patients is likely related to their milder phenotype (lacking tinnitus) compared with those of six previous DFNA6/14 patients with WFS1mutations. It is likely that a genotype-phenotype correlation is also applicable in the case of DFNA6/14/38.

Abstract
A 20-year-old Japanese man was admitted to our hospital because of thirst and weight loss. His fasting plasma glucose, glycated hemoglobin, and urinary C-peptide were 262 mg/dl, 13.6%, and 44.8 microg/day, respectively, and the autoimmune antibodies related to type 1 diabetes were negative. Chromosome analysis of his peripheral blood lymphocytes showed a mos45,XY,der(14;14)(q10;ql0)[129]/ 46,XY,+14, der(14;14)(q10;q10)[1] karyotype. His parents were karyotypically normal. Microsatellite marker analysis on chromosome 14 demonstrated mosaic maternal segmental isodisomy for 14q21-q24. Although the parents had normal glucose regulation, the patient who finally returned to impaired glucose tolerance and his mother both have a deficiency in early postprandial insulin secretion. Since obesity was mild (body mass index, 24.1 kg/m2) and he was relatively young for type 2 diabetes, we speculated that his isodisomy 14 may have been involved in the onset of diabetes mellitus in this patient.

Abstract
We describe a duplication of the 8p23.2 band in seven individuals from four families. The duplication was recognizable as an enlarged 8p23.2 band on G-banded chromosomes at the 550 band level. It was transmitted from a parent to offspring in three of the four families in which both parents were karyotyped. Each proband in the four families had the enlarged band and showed various phenotypic abnormalities, but the abnormalities were inconsistent. Chromosomal and interphase fluorescence in situ hybridization (FISH) analysis of the enlarged band region defined a 2.5-Mb duplicated segment common to all seven individuals studied. Interphase FISH analysis of peripheral blood lymphocytes from 50 unrelated normal individuals showed the duplication in three individuals. In view of these findings, it is most likely that the 8p23.2 duplication we described is a normal variant.

Abstract
We report on a Thai family with dominantly inherited malformation syndrome with upper limb anomalies, short stature, quadricuspid aortic valve, and minor craniofacial anomalies. The affected individuals comprised a mildly affected mother, a moderately affected daughter, and a most severely affected son. The daughter and son had short stature. The craniofacial abnormalities comprised frontal bossing, hypoplastic nasal bones, depressed nasal bridge, and broad nasal alae. The upper limb defects varies among the patients, ranging from radial ray defects in the mother through radial and ulnar ray defects with unilateral humeral hypoplasia in the daughter to radial ray defects with severe oligodactyly and bilateral humeral hypoplasia in the son. All patients in this family had hypoplasia of the shoulder girdle and resembled what is observed in many families with Holt-Oram syndrome. Moreover, the son showed quadricuspid aortic valve with mild aortic regurgitation. However, the present family did not show any mutation of the TBX5 gene, a disease-causing gene of Holt-Oram syndrome. The present family deserves further investigation on other genes that play a role in the development of the upper limbs, particularly of radial rays.

Abstract
We report a 20-year-old man with maternal uniparental disomy for chromosome 14 (UPD14) and maturity-onset diabetes mellitus (DM). He had pre- and postnatal growth retardation, developed DM at age 20 years without any autoimmune antibodies, and had a mosaic 45,XY,der(14;14)(q10;q10)[129]/46,XY,+14,der(14;14)(q10;q10)[1] karyotype. Allelotyping using microsatellite markers covering the entire 14q indicated segmental maternal isodisomy for 14q21-q24 and maternal heterodisomy of the remaining regions of the chromosome. It is thus tempting to speculate that the segmental isodisomy led to reduction to homozygosity for a mutant gene and thus caused his DM, although the possibility of coincidental occurrence of the two events cannot totally be ruled out. Fluorescence in situ hybridization (FISH) analysis using BAC clone probes revealed that the isodisomic segment did not overlap any known IDDM or NIDDM susceptibility loci on chromosome 14, suggesting a novel locus for a subset of DM at the isodisomic segment.
