Abstract
BACKGROUND Familial benign chronic pemphigus, also known as Hailey-Hailey disease (HHD), is a clinically rare bullous Dermatosis. However the mechanism has not been clarified. The study aim to detect novel mutations in exons of ATP2C1 gene in HHD patients; to explore the possible mechnism of HHD pathogenesis by examining the expression profile of hSPCA1, miR-203, p63, Notch1 and HKII proteins in the skin lesions of HHD patients. METHODS Genomic DNA was extracted from peripheral blood of HHD patients. All exons of ATP2C1 gene in HHD patients were amplified by PCR and the products were purified and sequenced. All related signaling proteins of interest were stained by using skin lesion tissues from HHD patients and miR-203 levels were also determined. RESULTS One synonymous mutation c.G2598A (in exon 26), one nonsense mutation c.C635A and two missense mutations c.C1286A (p.A429D) and c. A1931G (p. D644G) were identified. The nonsense mutation changed codon UCG to stop codon UAG, causing a premature polypeptide chain of the functional region A. The two missense mutations were located in the region P (phosphorylation region) and the Mn binding site of hSPCA1. The level of hSPCA1 was significantly decreased in HHD patients compared to the normal human controls, accompanied by an increase of miR-203 level and a decrease of p63 and HKII levels. CONCLUSION In our study, we found four mutations in HHD. Meanwhile we found increase of miR-203 level and a decrease of p63 and HKII levels. In addition, Notch1, which was negatively regulated p63, is downregulated. These factors may be involved in the signaling pathways of HHD pathogenesis. Our data showed that both p63 and miR-203 may have significant regulatory effects on Notch1 in the skin.

Abstract
Our previous results pointed to a putative gene for susceptibility to bipolar affective disorder located on the chromosomal region 12q23-q24 that segregated in the Saguenay-Lac-St-Jean population of Quebec. We report here results from a second genome-wide scan based on the analysis of 380 polymorphic microsatellite markers. For the purpose of this analysis, an additional 18 families were recruited from the Saguenay-Lac-St-Jean region and pooled to our previous sample to improve its statistical power, giving a total of 394 sampled individuals. This work confirms the presence of a susceptibility locus for affective disorder on chromosome 12q24 with parametric LOD score value of 3.35 at D12S378 when pedigrees were broken into nuclear families and analysed under a recessive segregation model. This result was supported by neighbouring markers and by a LOD score value of 5.05 at D12S378 under model-free analysis. Other regions of lower interest were indicated on chromosomes 2, 5, 7, 9, 10, 17 and 20.

Abstract
Darier disease (DD) is with a frequency of up to 1 in 36,000 a relatively common genodermatosis with autosomal dominant inheritance and late age of onset. The progressive skin manifestations are variable, but often debilitating and disfiguring, and may be associated with a wide range of neuropsychiatric problems, such as epilepsy and depression. On histology, acantholysis and dyskeratosis are prominent findings, implicating impaired functionality of desmosomes. Recently, mutations in the ATP2A2 gene encoding SERCA2, a calcium pump of the endo/sacrcoplasmic reticulum, have been identified as the molecular basis of DD. This slow-twitched calcium ATPase has two splice variants, one of which is highly expressed in epidermis, and maintains low intracellular calcium levels by facilitating transport of cytosolic calcium into the endoplasmic reticulum. Thus, it may confer a direct effect on the established calcium-dependent assembly of desmosomes. We screened ATP2A2 in a cohort of 24 DD families using conformation sensitive gel electrophoresis and direct sequencing, and detected 14 distinct mutations, 9 of which were novel. The mutational spectrum included 9 missense mutations, 1 nonsense mutation, 3 small in-frame deletions, and a 19-basepair insertion. Mutations were scattered over the entire gene with a slight preponderance in the first 8 exons, and affected exclusively residues conserved among all SERCAs. In addition, we found 2 silent polymorphisms, 1 of which occurred in 4 unrelated families. Comparison of molecular data and phenotypic features, such as severity and type of disease, occurrence of mucosal involvement, or association with neuropsychiatric disorders, did not reveal an obvious genotype-phenotype correlation in our cohort.

Abstract
We previously assigned the disease locus for autosomal dominant hereditary motor neuropathy type II (distal HMN II) within a 13-cM interval at chromosome 12q24.3. We constructed a physical map of the distal HMN II region based on yeast artificial chromosomes (YACs), P1 artificial chromosomes (PACs), and bacterial artificial chromosomes (BACs) using an STS content mapping approach. The contig contains 26 YAC, 15 PAC, and 60 BAC clones and covers a physical distance of approximately 5 Mb. A total of 99 STS markers, including 25 known STSs and STRs, 49 new STSs generated from clone end-fragments, 20 ESTs, and 5 known genes, were located on the contig. This physical map provides a valuable resource for mapping genes and markers located within the distal HMN II region and facilitates the positional cloning of the distal HMN II gene.

Abstract
BACKGROUND Darier-White disease, or keratosis follicularis, is a dominantly inherited disorder characterized by brown hyperkeratotic papules and plaques in a seborrheic distribution. The genetic basis of this disorder has recently been elucidated. OBJECTIVE In this article, we review the history of the search for the genetic basis of Darier-White disease. METHODS Previous studies are reviewed in which linkage studies identified the chromosomal location of the disease gene. The methods of physical mapping of the critical gene region and the screening of candidate genes are discussed. Results of recently published data on genotype-phenotype correlation in the disorder are presented. RESULTS Linkage analysis in families, together with development of a physical map of the critical region was important in identifying the causative gene. Screening of candidate genes led to the discovery that mutations in ATP2A2, a gene that encodes the sarco/endoplasmic reticulum Ca(2+)-ATPase isoform 2, cause Darier-White disease. Abnormalities in the function of this calcium pump are hypothesized to interfere with cell growth and differentiation calcium-dependent processes. CONCLUSION Genetic and molecular approaches have identified the gene for Darier-White disease and lead to more questions, including "Will this information help in the search for the Hailey-Hailey disease gene?"

Abstract
Charcot-Marie-Tooth disease type 4B (CMT4B) is a demyelinating autosomal recessive motor and sensory neuropathy characterized by focally folded myelin sheaths in the peripheral nerve. We recently mapped the CMT4B gene to a 5-cM interval on chromosome 11q22, using homozygosity mapping and haplotype sharing analysis on a large inbred pedigree. In the present study, we report the construction of a YAC-based transcript map across the 5-cM critical region, including 26 YACs, 35 STSs, and 52 ESTs. Furthermore, using 15 additional physically ordered microsatellite markers from the 11q22 region on the original inbred family, we were able to narrow the critical interval for the gene to 2 Mb, which is now flanked by markers D11S1757 and CHLC-GATA3B05. Finally, after computer analysis of the 33 ESTs assigned to the 2-Mb interval, we demonstrated that 21 different transcripts as well as 3 known genes might represent potential candidates for the disease.

Abstract
We completed a genome-wide scan for susceptibility loci for bipolar affective disorders in families derived from a rather homogeneous population in the Province of Québec. The genetic homogeneity of this population stems from the migration of founding families into this relatively isolated area of Québec in the 1830s. A possible founder effect, combined with a prevalence of very large families, makes this population ideal for linkage studies. Genealogies for probands can be readily constructed from a population database of acts of baptism and marriage from the early 1830s up to the present time (the BALSAC register). We chose probands with a DSM III diagnosis of bipolar affective disorder and who may be grouped within large families having genealogical origins with the founding population of the Saguenay-Lac-St-Jean area. Living members (n approximately 120) of a very large pedigree were interviewed using the Structured Clinical Interview for DSM III (SCID I), SCID II, and with a family history questionnaire. A diagnostic panel evaluated multisource information (interview, medical records, family history) and pronounced best-estimate consensus diagnoses on all family members. Linkage, SimAPM, SimIBD, and sib-pair analyses have been performed with 332 microsatellite probes covering the entire genome at an average spacing of 11 cM. GENEHUNTER and haplotype analyses were performed on regions of interest. Analysis of a second large pedigree in the same regions of interest permitted confirmation of presumed linkages found in the region of chromosome 12q23-q24.

Abstract
X-linked dystonia-parkinsonism (XDP) is a recessive disorder characterized by generalized dystonia with some patients exhibiting parkinsonism. The disease gene, DYT3, is located between DXS453 (DXS993) and DXS559, and strongest linkage disequilibrium is found distal to DXS7117 and proximal to DXS559. We have isolated and analyzed four novel polymorphic markers between DXS7117 and DXS559 and, by haplotype analysis, have narrowed the candidate interval to <350 kb. A sequence-ready contig of 700 kb has been constructed spanning DXS7117 to DXS559 and is composed of 35 PACs, BACs, and cosmids. Nine genes and novel ESTs have been mapped into this contig, and mutations in the coding regions and intron-exon borders of two genes have been excluded as the cause of XDP. Several of the other genes and ESTs located within the contig code for proteins implicated in normal brain development and function and are candidates for DYT3.

Abstract
Darier's disease (DD) is an autosomal dominantly inherited skin disorder characterized by loss of adhesion between epidermal cells (acantholysis) and abnormal keratinization. Recently, we identified ATP2A2 encoding the sarco/endoplasmic reticulum Ca(2+)ATPase isoform 2 as the defective gene in DD. Now we report a spectrum of ATP2A2 mutations in 19 families and six sporadic cases with DD and investigate genotype-phenotype correlations. All 21 exons and flanking intron boundaries were amplified and screened for mutations by conformation-sensitive gel electrophoresis and direct sequencing. We identified 24 novel mutations that are scattered throughout the ATP2A2 gene. Two families shared an identical mutation on a common disease-associated haplotype, suggesting inheritance from a common ancestor. The majority of the mutations (54%; 13/24) led to a premature termination codon which further supports the proposal that haploin-sufficiency is a common molecular mechanism for DD. Thirty-eight per cent of mutations (9/24) result in non-conservative amino acid substitutions at highly conserved positions. Two mutations predict mutated polypeptides lacking or carrying additional amino acids. Marked inter- and intrafamilial phenotypic variability of the disease was observed. These results illustrate the considerable diversity of ATP2A2 mutations causing DD and suggest that additional factors are important contributors to the clinical phenotype.

Abstract
Darier's disease (DD) is an autosomal dominant skin disorder characterized clinically by multiple keratotic papules, and histologically by focal loss of adhesion between epidermal cells (acantholysis) and by abnormal keratinization. Variant forms of cutaneous phenotype, sometimes familial, have been described. Associated neuropsychiatric features, including mental handicap, schizophrenia, bipolar disorder and epilepsy, have also been reported. The cause of DD was shown recently to be mutation in the ATP2A2 gene at 12q24.1, which encodes the sarco-endoplasmic reticulum calcium ATPase type 2 (SERCA2). Here, we show that while both common isoforms of SERCA2 are expressed in the cytoplasm of cultured keratinocytes and fibroblasts, in adult skin sections only the longer isoform, SERCA2b, was expressed abundantly in epidermal structures. Extended mutation analysis in European DD patients using single-strand conformation polymorphism and/or direct sequencing identified 40 different patient-specific mutations in 47 families. The majority (23/40) were likely to result in nonsense-mediated RNA decay. The remaining 17 were missense mutations distributed throughout the protein and were associated significantly with atypical clinical features. The clearest association was with the familial haemorrhagic variant where all four families tested had a missense mutation. Three of the families (one Scottish family and two unrelated Italian families) exhibited the same N767S substitution in the M5 transmembrane domain, and a fourth family, from Sweden, had a C268F substitution in the M3 transmembrane domain. Neuropsychiatric features did not appear to be associated with a specific class of mutation and may be an intrinsic, but inconsistent, effect of defective ATP2A2 expression.

Abstract
Chorea-acanthocytosis (CHAC) (OMIM 200150) is a rare neurological syndrome characterized by neurodegeneration in combination with morphologically abnormal red cells (acanthocytosis). A partial yeast artificial chromosome contig of the CHAC critical region on chromosome 9q21 has been constructed, and 21 expressed sequence tags have been mapped. We have subsequently cloned Galpha14, a member of the G-protein alpha-subunit multigene family, and have identified Galphaq in the contig. The genomic structure of both genes has been established after construction of a bacterial artificial chromosome contig that showed Galphaq and Galpha14 to be in a head-to-tail arrangement (Cen-Galphaq-Galpha14-qter). Northern analysis found Galphaq to be ubiquitously expressed and Galpha14 to display a more restricted pattern of expression. Mutation analysis of the coding regions and splice sites for Galphaq and Galpha14 in 10 affected individuals from different families identified no changes likely to cause disease; however, two distinct single nucleotide polymorphisms in the coding region of Galpha14 have been identified. This study has excluded two plausible candidate genes from involvement in CHAC and has provided a solid platform for a positional cloning initiative.

Abstract
Darier disease (DD) is an autosomal-dominant skin disorder characterized by loss of adhesion between epidermal cells (acantholysis) and abnormal keratinization. Recently we constructed a 2.4-Mb, P1-derived artificial chromosome contig spanning the DD candidate region on chromosome 12q23-24.1. After screening several genes that mapped to this region, we identified mutations in the ATP2A2 gene, which encodes the sarco/endoplasmic reticulum Ca2(+)-ATPase type 2 isoform (SERCA2) and is highly expressed in keratinocytes. Thirteen mutations were identified, including frameshift deletions, in-frame deletions or insertions, splice-site mutations and non-conservative missense mutations in functional domains. Our results demonstrate that mutations in ATP2A2 cause DD and disclose a role for this pump in a Ca(2+)-signalling pathway regulating cell-to-cell adhesion and differentiation of the epidermis.
