Abstract
Non-Floating Harbour Syndrome (FLHS) neurodevelopmental disorder (NDD) is a recently described disorder caused by mutations in certain regions of the SRCAP gene. We generated two iPSC lines that contain truncating mutation on both alleles at the 3'-end of SRCAP using CRISPR/Cas9 technology. Both cell lines are pluripotent, differentiate into the 3 germ layers and contain no genomic aberrations or off-target modifications. The cell lines form part of a human disease model to investigate the effects of truncating mutations in different regions of SRCAP.

Abstract
Dicentric chromosome analysis (DCA) is the gold standard for individual radiation dose assessment. However, DCA is limited by the time-consuming phytohemagglutinin (PHA)-mediated lymphocyte activation. In this study using human peripheral blood lymphocytes, we investigated PHA-associated whole genome gene expression changes to elucidate this process and sought to identify suitable gene targets as a means of meeting our long-term objective of accelerating cell cycle kinetics to reduce DCA culture time. Human peripheral whole blood from three healthy donors was separately cultured in RPMI/FCS/antibiotics with BrdU and PHA-M. Diluted whole blood samples were transferred into PAXgene tubes at 0, 12, 24 and 36 h culture time. RNA was isolated and aliquots were used for whole genome gene expression screening. Microarray results were validated using qRT-PCR and differentially expressed genes [significantly (FDR corrected) twofold different from the 0 h value reference] were analyzed using several bioinformatic tools. The cell cycle positions and DNA-synthetic activities of lymphocytes were determined by analyzing the correlated total DNA content and incorporated BrdU level with flow cytometry after continued BrdU incubation. From 42,545 transcripts of the whole genome microarray 47.6%, on average, appeared expressed. The number of differentially expressed genes increased linearly from 855 to 2,858 and 4,607 at 12, 24 and 36 h after PHA addition, respectively. Approximately 2-3 times more up- than downregulated genes were observed with several hundred genes differentially expressed at each time point. Earliest enrichment was observed for gene sets related to the nucleus (12 h) followed by genes assigned to intracellular structures such as organelles (24 h) and finally genes related to the membrane and the extracellular matrix were enriched (36 h). Early gene expression changes at 12 h, in particular, were associated with protein classes such as chemokines/cytokines (e.g., CXCL1, CXCL2) and chaperones. Genes coding for biological processes involved in cell cycle control (e.g., MYBL2, RBL1, CCNA, CCNE) and DNA replication (e.g., POLA, POLE, MCM) appeared enriched at 24 h and later, but many more biological processes (42 altogether) showed enrichment as well. Flow cytometry data fit together with gene expression and bioinformatic analyses as cell cycle transition into S phase was observed with interindividual differences from 12 h onward, whereas progression into G2 as well as into the second G1 occurred from 36 h onward after activation. Gene set enrichment analysis over time identifies, in particular, two molecular categories of PHA-responsive gene targets (cytokine and cell cycle control genes). Based on that analysis target genes for cell cycle acceleration in lymphocytes have been identified ( CDKN1A/B/C, RBL-1/RBL-2, E2F2, Deaf-1), and it remains undetermined whether the time expenditure for DCA can be reduced by influencing gene expression involved in the regulatory circuits controlling PHA-associated cell cycle entry and/or progression at a specific early cell cycle phase.

Abstract
X-linked intellectual disability (XLID) is a clinically and genetically heterogeneous disorder. During the past two decades in excess of 100 X-chromosome ID genes have been identified. Yet, a large number of families mapping to the X-chromosome remained unresolved suggesting that more XLID genes or loci are yet to be identified. Here, we have investigated 405 unresolved families with XLID. We employed massively parallel sequencing of all X-chromosome exons in the index males. The majority of these males were previously tested negative for copy number variations and for mutations in a subset of known XLID genes by Sanger sequencing. In total, 745 X-chromosomal genes were screened. After stringent filtering, a total of 1297 non-recurrent exonic variants remained for prioritization. Co-segregation analysis of potential clinically relevant changes revealed that 80 families (20%) carried pathogenic variants in established XLID genes. In 19 families, we detected likely causative protein truncating and missense variants in 7 novel and validated XLID genes (CLCN4, CNKSR2, FRMPD4, KLHL15, LAS1L, RLIM and USP27X) and potentially deleterious variants in 2 novel candidate XLID genes (CDK16 and TAF1). We show that the CLCN4 and CNKSR2 variants impair protein functions as indicated by electrophysiological studies and altered differentiation of cultured primary neurons from Clcn4(-/-) mice or after mRNA knock-down. The newly identified and candidate XLID proteins belong to pathways and networks with established roles in cognitive function and intellectual disability in particular. We suggest that systematic sequencing of all X-chromosomal genes in a cohort of patients with genetic evidence for X-chromosome locus involvement may resolve up to 58% of Fragile X-negative cases.

Abstract
Submicroscopic duplications along the long arm of the X-chromosome with known phenotypic consequences are relatively rare events. The clinical features resulting from such duplications are various, though they often include intellectual disability, microcephaly, short stature, hypotonia, hypogonadism and feeding difficulties. Female carriers are often phenotypically normal or show a similar but milder phenotype, as in most cases the X-chromosome harbouring the duplication is subject to inactivation. Xq28, which includes MECP2 is the major locus for submicroscopic X-chromosome duplications, whereas duplications in Xq25 and Xq26 have been reported in only a few cases. Using genome-wide array platforms we identified overlapping interstitial Xq25q26 duplications ranging from 0.2 to 4.76 Mb in eight unrelated families with in total five affected males and seven affected females. All affected males shared a common phenotype with intrauterine- and postnatal growth retardation and feeding difficulties in childhood. Three had microcephaly and two out of five suffered from epilepsy. In addition, three males had a distinct facial appearance with congenital bilateral ptosis and large protruding ears and two of them showed a cleft palate. The affected females had various clinical symptoms similar to that of the males with congenital bilateral ptosis in three families as most remarkable feature. Comparison of the gene content of the individual duplications with the respective phenotypes suggested three critical regions with candidate genes (AIFM1, RAB33A, GPC3 and IGSF1) for the common phenotypes, including candidate loci for congenital bilateral ptosis, small head circumference, short stature, genital and digital defects.

Abstract
Accidents with ionizing radiation often involve single, acute high-dose exposures that can lead to acute radiation syndrome and late effects such as carcinogenesis. To study such effects at the cellular level, we investigated acute ionizing radiation-induced chromosomal aberrations in A549 adenocarcinoma cells at the genome-wide level by exposing the cells to an acute dose of 6 Gy 240 kV X rays. One sham-irradiated clone and four surviving irradiated clones were recovered by minimal dilution and further expanded and analyzed by chromosome painting and tiling-path array CGH, with the nonirradiated clone 0 serving as the control. Acute X-ray exposure induced specific translocations and changes in modal chromosome number in the four irradiated clones. Array CGH disclosed unique and recurrent genomic changes, predominantly losses, and revealed that the fragile sites FRA3B and FRA16D were preferential regions of genomic alterations in all irradiated clones, which is likely related to radioresistant S-phase progression and genomic stress. Furthermore, clone 4 displayed an increased radiosensitivity at doses >5 Gy. Pairwise comparisons of the gene expression patterns of all irradiated clones to the sham-irradiated clone 0 revealed an enrichment of the Gene Ontology term "M Phase" (P = 6.2 × 10(-7)) in the set of differentially expressed genes of clone 4 but not in those of clones 1-3. Ionizing radiation-induced genomic changes and fragile site expression highlight the capacity of a single acute radiation exposure to affect the genome of exposed cells by inflicting genomic stress.

Abstract
OBJECTIVE Congenital hypothyroidism occurs in 1:3500 live births and is therefore the most common congenital endocrine disorder. A spectrum of defective thyroid morphology, termed thyroid dysgenesis (TD), represents 80% of permanent congenital hypothyroidism cases. Although several candidate genes have been implicated in thyroid development, comprehensive screens failed to detect mutation carriers in a significant number of patients with nonsyndromic TD. Due to the sporadic occurrence of TD, de novo chromosomal rearrangements are conceivably representing one of the molecular mechanisms participating in its etiology. METHODS The introduction of array comparative genomic hybridization (CGH) has provided the ability to map DNA copy number variations (CNVs) genome wide with high resolution. We performed an array CGH screen of 80 TD patients to determine the role of CNVs in the etiology of the disease. RESULTS We identified novel CNVs that have not been described as frequent variations in the healthy population in 8.75% of all patients. These CNVs exclusively affected patients with athyreosis or thyroid hypoplasia and were nonrecurrent, and the regions flanking the CNVs were not enriched for segmental duplications. CONCLUSIONS The high rate of chromosomal changes in TD argues for an involvement of CNVs in the etiology of this disease. Yet the lack of recurrent aberrations suggests that the genetic causes of TD are heterogenous and not restricted to specific genomic hot spots. Thus, future studies may have to shift the focus from singling out specific genes to the identification of deregulated pathways as the underlying cause of the disease.

Abstract
Campomelic dysplasia (MIM 114290) is a severe malformation syndrome frequently accompanied by male-to-female sex reversal. Causative are mutations within the SOX9 gene on 17q24.3 as well as chromosomal aberrations (translocations, inversions or deletions) in the vicinity of SOX9. Here, we report on a patient with muscular hypotonia, craniofacial dysmorphism, cleft palate, brachydactyly, malformations of thoracic spine, and gonadal dysgenesis with female external genitalia and müllerian duct derivatives in the presence of a male karyotype. X-ray examination and clinical examinations revealed no signs of campomelia. The combination of molecular cytogenetic analysis and array CGH revealed an unbalanced translocation between one chromosome 7 and one chromosome 17 [46,XY,t(7;17)(q33;q24).ish t(7;17)(wcp7+,wcp17+;wcp7+wcp17+)] with a deletion of approximately 4.2 Mb located about 0.5 Mb upstream of SOX9. STS analysis confirmed the deletion of chromosome 17, which has occurred de novo on the paternal chromosome. The proximal breakpoint on chromosome 17 is localized outside the known breakpoint cluster regions. The deletion on chromosome 17q24 removes several genes. Among these genes PRKAR1A is deleted. Inactivating mutations of PRKAR1A cause Carney complex. To our knowledge, this is the first report of a patient with acampomelic campomelic dysplasia, carrying both a deletion and a translocation.

Abstract
Zusammenfassung
Unter strukturellen Genomvarianten (SV) versteht man chromosomale Veränderungen größer als 1 kb. Obwohl es dank des technischen Fortschritts immer besser gelingt, die qualitativen und quantitativen Eigenschaften von SV zu definieren, sind deren phänotypischen Konsequenzen meist nur unzureichend verstanden. Die Unterscheidung zwischen neutraler Variante, prädisponierendem Faktor und krankheitsverursachender Veränderung stellt heute eine der großen Herausforderungen in der humangenetischen Diagnostik dar.

Abstract
BACKGROUND Congenital heart disease (CHD) is the most common birth defect and affects nearly 1% of newborns. The aetiology of CHD is largely unknown and only a small percentage can be assigned to environmental risk factors such as maternal diseases or exposure to mutagenic agents during pregnancy. Chromosomal imbalances have been identified in many forms of syndromic CHD, but very little is known about the impact of DNA copy number changes in non-syndromic CHD. METHOD A sub-megabase resolution array comparative genome hybridisation (CGH) screen was carried out on 105 patients with CHD as the sole abnormality at the time of diagnosis. RESULTS There were 18 chromosomal changes detected, which do not coincide with common DNA copy number variants, including one de novo deletion, two de novo duplications and eight familial copy number variations (one deletion and seven duplications). CONCLUSIONS Our data show that submicroscopic deletions and duplications play an important role in the aetiology of this condition, either as direct causes or as genetic risk factors for CHD. These findings have immediate consequences for genetic counselling and should pave the way for the elucidation of the pathogenetic mechanisms underlying CHD.

Abstract
Nievergelt syndrome (NS) is an autosomal dominant mesomelic dysplasia characterized by specific deformities of the radius, ulna, fibula and a rhomboid shape of the tibia. Phenotypically overlapping conditions such as mesomelic dysplasia, Savarirayan-type (MIM 605274), have been described, but their pathogenesis also remains unknown. We report on a girl with fibular agenesis, severely abnormal, triangular tibiae, urogenital tract malformations, failure to thrive, convulsions and recurrent apnoeas leading to respiratory arrest at the age of 4 months. Her skeletal findings correspond to those of the mesomelic dysplasia, Savarirayan-type recently described in two patients. In addition to the skeletal findings, our patient had central nervous system manifestations and developmental anomalies of the urogenital tract. In the patient described in this study, array comparative genomic hybridization (CGH) analysis revealed a de novo interstitial microdeletion of 500 kb on chromosome 2q11.1 containing the LAF4/AFF3 (lymphoid-nuclear-protein-related AF4) gene. In situ hybridization analysis of Laf4 in mouse embryos revealed expression in the developing brain, in the limb buds and in the zeugopod corresponding to the limb phenotype. Haploinsufficiency for LAF4/AFF3 is associated with limb, brain and urogenital malformations and specific changes of the tibia that are part of the NS spectrum.

Abstract
Mowat-Wilson syndrome (MWS) is an autosomal dominant developmental disorder with mental retardation and variable multiple congenital abnormalities due to mutations of the ZEB2 (ZFHX1B) gene at 2q22. MWS was first described in 1998 and the causative gene was delineated in 2001. Since then, 115 different mutations of ZEB2 have been published in association with this syndrome in 161 individuals. However, recent reports suggest that due to the variability of the congenital abnormalities, this syndrome may still be underdiagnosed. We report two unrelated patients with MWS where the clinical diagnosis was established only after finding of disruption of the ZEB2 gene by a balanced translocation breakpoint and an interstitial microdeletion, respectively.

Abstract
BACKGROUND Sonic hedgehog (SHH) plays an important role in defining the anterior-posterior axis in the developing limbs. A highly conserved non-coding sequence about approximately 1 Mb upstream from the sonic hedgehog gene (SHH) was shown to be a long range regulator for SHH expression in the limb bud. Point mutations within this non-coding regulatory region designated ZRS lead to ectopic expression of Shh in the anterior margin of the limb bud, as shown in mice, and cause the human triphalangeal thumb and polysyndactyly (TPT-PS) phenotype. Even though this association is well established, its molecular mechanism remains unclear. METHODS AND RESULTS We investigated a large pedigree with variable TPT-PS. A single nucleotide exchange within the SHH limb regulator sequence was excluded, but locus specific microsatellite marker analyses confirmed a linkage to this region. Subsequently, array comparative genomic hybridisation (array CGH) was carried out using a submegabase whole human genome tiling path bacterial artificial chromosome (BAC) array revealing a microduplication in 7q36.3 in affected individuals. A duplicated region of 588,819 bp comprising the ZRS was identified by quantitative real-time polymerase chain reaction (qPCR) and direct sequencing. CONCLUSION A novel microduplication in 7q36.3 results in a similar TPT-PS phenotype as caused by single nucleotide alterations in the ZRS, the limb specific SHH regulatory element. Duplications can be added to the growing list of mechanisms that cause abnormalities of long range transcriptional control.

Abstract
Most patients with neurofibromatosis (NF1) are endowed with heterozygous mutations in the NF1 gene. Approximately 5% show an interstitial deletion of chromosome 17q11.2 (including NF1) and in most cases also a more severe phenotype. Here we report on a 7-year-old girl with classical NF1 signs, and in addition mild overgrowth (97th percentile), relatively low OFC (10th-25th percentile), facial dysmorphy, hoarse voice, and developmental delay. FISH analysis revealed a 17q11.2 microdeletion as well as an unbalanced 7p;13q translocation leading to trisomy of the 7q36.3 subtelomeric region. The patient's mother and grandmother who were phenotypically normal carried the same unbalanced translocation. The 17q11.2 microdeletion had arisen de novo. Array comparative genomic hybridization (CGH) demonstrated gain of a 550-kb segment from 7qter and loss of 2.5 Mb from 17q11.2 (an atypical NF1 microdeletion). We conclude that the patient's phenotype is caused by the atypical NF1 deletion, whereas 7q36.3 trisomy represents a subtelomeric copy number variation without phenotypic consequences. To our knowledge this is the first report that a duplication of the subtelomeric region of chromosome 7q containing functional genes (FAM62B, WDR60, and VIPR2) can be tolerated without phenotypic consequences. The 17q11.2 microdeletion (containing nine more genes than the common NF1 microdeletions) and the 7qter duplication were not accompanied by unexpected clinical features. Most likely the 7qter trisomy and the 17q11.2 microdeletion coincide by chance in our patient.

Abstract
We report on a 30-year-old man with azoospermia, primary hypogonadism and minor dysmorphic features who carried a balanced insertional chromosome translocation inv ins (2p24;4q28.3q31.22)de novo. Molecular cytogenetic analyses of the chromosome breakpoints revealed the localization of the breakpoint in 4q28.3 between BACs RP11-143E9 and RP11-285A15, an interval that harbours the PCDH10 gene. In 4q31.22, a breakpoint-spanning clone (RP11-6L6) was identified which contains the genes LSM6 and SLC10A7. On chromosome 2, BACs RP11-531P14 and RP11-360O18 flank the breakpoint in 2p24, a region void of known genes. In conclusion, the chromosome aberration of this patient suggests a gene locus for primary hypogonadism in 2p24, 4q28.3 or 4q31.2, and three possible candidate genes (LSM6, SLC10A7 and PCDH10) were identified by breakpoint analyses.

Abstract
Low copy repeats (LCRs) are stretches of duplicated DNA that are more than 1 kb in size and share a sequence similarity that exceeds 90%. Non-allelic homologous recombination (NAHR) between highly similar LCRs has been implicated in numerous genomic disorders. This study aimed at defining the impact of LCRs on the generation of balanced and unbalanced chromosomal rearrangements in mentally retarded patients. A cohort of 22 patients, preselected for the presence of submicroscopic imbalances, was analysed using submegabase resolution tiling path array CGH and the results were compared with a set of 41 patients with balanced translocations and breakpoints that were mapped to the BAC level by FISH. Our data indicate an accumulation of LCRs at breakpoints of both balanced and unbalanced rearrangements. LCRs with high sequence similarity in both breakpoint regions, suggesting NAHR as the most likely cause of rearrangement, were observed in 6/22 patients with chromosomal imbalances, but not in any of the balanced translocation cases studied. In case of chromosomal imbalances, the likelihood of NAHR seems to be inversely related to the size of the aberration. Our data also suggest the presence of additional mechanisms coinciding with or dependent on the presence of LCRs that may induce an increased instability at these chromosomal sites.

Abstract
We report on a currently six-year-old patient with a de novo complex chromosome rearrangement (CCR) involving chromosomes 2 and 12. A translocation 2;12 that appeared to be reciprocal after standard banding turned out to be a complex event with seven breaks after molecular cytogenetic analyses. Array CGH analysis showed no imbalances at the breakpoints but revealed an additional microdeletion of about 80 kb on chromosome 11. The same deletion was also present in the phenotypically normal father. The patient showed relatively mild mental retardation, defined mainly as impaired speech development (orofacial dyspraxia) and psychomotor retardation. In addition, mild dysmorphic facial features like hypertelorism, a prominent philtrum and down-turned corners of the mouth were observed. We narrowed down all breakpoint regions to about 100 kb, using a panel of mapped bacterial artificial chromosome (BAC) clones for fluorescence in situ hybridization (FISH). BACs spanning or flanking all seven breakpoints were identified and no chromosomal imbalances were found consistent with the array CGH results. Our investigations resulted in the following karyotype: 46,XY,t(2;12)(2pter-->2p25.3::2p23.3-->2p25.2::2p23.3-->2p14::2q14.3-->2p14::2q14.3-->2q14.3::12q 12-->12qter;12pter-->12q12::2p25.3-->2p25.2::2q14.3-->2qter).

Abstract
The 22q11.2 microdeletion syndrome is the most frequent microdeletion syndrome in humans, yet its genetic basis is complex and is still not fully understood. Most patients harbor a 3-Mb deletion (typically deleted region [TDR]), but occasionally patients with atypical deletions, some of which do not overlap with each other and/or the TDR, have been described. Microduplication of the TDR leads to a phenotype similar, albeit not identical, to the deletion of this region. Here we present a child initially suspected of having 22q11 microdeletion syndrome, who in addition developed a fatal malignant rhabdoid tumor of the kidney. Detailed cytogenetic and molecular analyses revealed a complex de novo rearrangement of band q11 of the paternally derived chromosome 22. This aberration exhibited two novel features. First, a microduplication of the 22q11 TDR was associated with an atypical 22q11 microdeletion immediately telomeric of the duplicated region. Second, this deletion was considerably larger than previously reported atypical 22q11 deletions, spanning 2.8 Mb and extending beyond the SMARCB1/SNF5/INI1 tumor suppressor gene, whose second allele harbored a somatic frameshift-causing sequence alteration in the patient's tumor. Two nonallelic homologous recombination events between low-copy repeats (LCRs) could explain the emergence of this novel and complex mutation associated with the phenotype of 22q11 microdeletion syndrome.

Abstract
Atypical adenomatous hyperplasia (AAH) is a probable forerunner of bronchioloalveolar carcinoma (BAC) and pulmonary adenocarcinoma (AC) of mixed type. The present study analysed four low-grade AAHs, 13 high-grade AAHs, two BACs, nine mixed ACs, and one squamous cell carcinoma derived from 13 patients using comparative genomic hybridization. The average number of chromosomal aberrations was 1.2 in low-grade AAH, 9.6 in high-grade AAH, and 12.5 in AC. A high degree of overlap of genetic changes was found in high-grade AAH, BAC, and AC within individual patients. The high number of aberrations and the degree of shared aberrations found in high-grade AAH and AC raises questions about the separation of these two entities. In addition, in view of the monoclonal origin of multiple foci within the same patient, AAH may not be a precursor of AC in some cases, but rather may represent intraepithelial spread.

Abstract
Large-cell neuroendocrine carcinoma (LCNEC) and small-cell lung cancer (SCLC) are high-grade neuroendocrine tumors of the lung. Despite different morphologic appearances, loss of heterozygosity and oncogene studies on LCNEC to date suggest genetic similarities. We analyzed 13 LCNEC and 5 mixed SCLC/LCNEC tumors by comparative genomic hybridization and subsequently compared our results with previously published data on 32 SCLCs. Comparison with SCLC showed several shared chromosomal aberrations, specifically losses of 3p, 4q, 5q, and 13q and gains of 5p. However, these aberrations are no special feature of neuroendocrine lung tumors but can also be found in other high-grade lung carcinomas. From this point of view, genetic similarities of LCNEC and SCLC are less important than the nonrandom changes that differ between these 2 tumor types. A gain of 3q observed in 66% of all SCLCs was detected only once in the LCNEC group. In contrast to the pure LCNEC, all mixed types with a SCLC component had a gain of 3q. Gains of 6p occurred more frequently in LCNEC. Deletions of 10q, 16q, and 17p were less frequent in LCNEC than in SCLC.

Abstract
Classical chromosomal analysis and comparative genomic hybridization (CGH) were performed in a tubular bronchial gland adenoma. Trisomy of chromosomes 2, 11, 18 and 20 and clonal loss of Y were found in cultured cells derived from two different kryotubes; this was also confirmed by CGH from one of these tubes. Cells from two other tubes, investigated by CGH only, showed gains and losses of parts of chromosome 11q in one, and in the second additional gain of the distal portion of 9q and 17q, respectively. CGH analysis of tumor DNA extracted from paraffin-embedded sections showed no chromosomal imbalances. In cell culture growth the advantage of specific clones probably altered the clone distribution. This study highlights the risk of cytogenetic analysis based on cell cultures only.

Abstract
Neuroendocrine lung tumors such as typical carcinoid, atypical carcinoid, small-cell lung carcinoma, and large-cell neuroendocrine carcinoma represent a variable group with different biologic characteristics and unclear genetical relationships. We investigated the pattern of allelic loss on chromosome arm 11q in 20 sporadic carcinoid tumors of the lung using 10 microsatellite markers. Loss of heterozygosity was found in 13 of 20 tumors. In 5 of 9 typical carcinoids, 3 distinct regions of allelic loss were identified: 11q13.1 (D11S1883), 11q14.3-11q21 (D11S906), and 11q25 (D11S910). Atypical carcinoids showed loss of heterozygosity at 4 different regions: the first, most proximal region at 11q13 between markers PYGM and D11S937; the second at 11q14.3-11q21 (D11S906); and the third and fourth defined by markers D11S939 (11q23.2-23.3) and D11S910 (11q25). However, the region 11q13 harboring the MEN1 gene was more frequently affected in atypical carcinoids (7 of 11) than in typical carcinoids (2 of 9). The high rate of allelic losses within chromosomal region 11q13 in atypical carcinoids emphasizes the importance of this region for tumor development. We also recognized that more aggressive atypical carcinoids defined by high mitotic counts, vascular invasion, and/or organ metastasis are combined with increased allelic losses.

Abstract
C(4)-dicarboxylate transport is a prerequisite for anaerobic respiration with fumarate in Wolinella succinogenes, since the substrate site of fumarate reductase is oriented towards the cytoplasmic side of the membrane. W. succinogenes was found to transport C(4)-dicarboxylates (fumarate, succinate, malate, and aspartate) across the cytoplasmic membrane by antiport and uniport mechanisms. The electrogenic uniport resulted in dicarboxylate accumulation driven by anaerobic respiration. The molar ratio of internal to external dicarboxylate concentration was up to 10(3). The dicarboxylate antiport was either electrogenic or electroneutral. The electroneutral antiport required the presence of internal Na(+), whereas the electrogenic antiport also operated in the absence of Na(+). In the absence of Na(+), no electrochemical proton potential (delta p) was measured across the membrane of cells catalyzing fumarate respiration. This suggests that the proton potential generated by fumarate respiration is dissipated by the concomitant electrogenic dicarboxylate antiport. Three gene loci (dcuA, dcuB, and dctPQM) encoding putative C(4)-dicarboxylate transporters were identified on the genome of W. succinogenes. The predicted gene products of dcuA and dcuB are similar to the Dcu transporters that are involved in the fumarate respiration of Escherichia coli with external C(4)-dicarboxylates. The genes dctP, -Q, and -M probably encode a binding-protein-dependent secondary uptake transporter for dicarboxylates. A mutant (DcuA(-) DcuB(-)) of W. succinogenes lacking the intact dcuA and dcuB genes grew by nitrate respiration with succinate as the carbon source but did not grow by fumarate respiration with fumarate, malate, or aspartate as substrates. The DcuA(-), DcuB(-), and DctQM(-) mutants grew by fumarate respiration as well as by nitrate respiration with succinate as the carbon source. Cells of the DcuA(-) DcuB(-) mutant performed fumarate respiration without generating a proton potential even in the presence of Na(+). This explains why the DcuA(-) DcuB(-) mutant does not grow by fumarate respiration. Growth by fumarate respiration appears to depend on the function of the Na(+)-dependent, electroneutral dicarboxylate antiport which is catalyzed exclusively by the Dcu transporters. Dicarboxylate transport via the electrogenic uniport is probably catalyzed by the DctPQM transporter and by a fourth, unknown transporter that may also operate as an electrogenic antiporter.

Abstract
Members of the myosin superfamily play crucial roles in cellular processes including management of the cortical cytoskeleton, organelle transport and signal transduction. GTPases of the Rho family act as key control elements in the reorganization of the actin cytoskeleton in response to growth factors, and other functions such as membrane trafficking, transcriptional regulation, growth control and development. Here, we describe a novel unconventional myosin from Dictyostelium discoideum, MyoM. Primary sequence analysis revealed that it has the appearance of a natural chimera between a myosin motor domain and a guanine nucleotide exchange factor (GEF) domain for Rho GTPases. The functionality of both domains was established. Binding of the motor domain to F-actin was ATP-dependent and potentially regulated by phosphorylation. The GEF domain displayed selective activity on Rac1-related GTPases. Overexpression, rather than absence of MyoM, affected the cell morphology and viability. Particularly in response to hypo-osmotic stress, cells overexpressing the MyoM tail domain extended massive actin-driven protrusions. The GEF was enriched at the tip of growing protuberances, probably through its pleckstrin homology domain. MyoM is the first unconventional myosin containing an active Rac-GEF domain, suggesting a role at the interface of Rac-mediated signal transduction and remodeling of the actin cytoskeleton.

Abstract
Typical and atypical carcinoids (TC, ATC) and small (SCLC) and large cell neuroendocrine carcinomas (LCNEC) constitute the spectrum of neuroendocrine lung tumors. Chromosomal aberrations have not been studied in LCNEC and only rarely in carcinoids. Only SCLCs have been investigated frequently for chromosomal aberrations. We compared three typical and four atypical carcinoids, one atypical carcinoid/SCLC mixed type, three SCLC, and three LCNEC for chromosomal gains and losses using comparative genomic hybridization. Typical carcinoids showed either no changes or only few chromosomal gains. Atypical carcinoids appeared genetically heterogeneous: One case had no aberrations, and three cases had few aberrations; two of them showed a deletion of 11q. SCLC and LCNEC were characterized by many gains and losses, especially similar changes of 3p, 5q, 5p, and 13q. Although ATC resemble LCNEC morphologically, there were no similarities at the genetic level. We have found a reciprocal relationship of prognosis and the amount of aberrations. TCs and ATCs with few chromosomal changes have the best prognosis, whereas SCLCs and LCNECs were generally characterized by a great amount of aberrations and worst prognosis. There was no unbalanced aberration common in all types of neuroendocrine tumors of the lung.

Abstract
The use of scanning tunneling microscopy in an electrochemical environment as a tool for the nanoscale modification of gold electrodes was demonstrated. Small copper clusters, typically two to four atomic layers in height, were precisely positioned on a gold(111) electrode by a process in which copper was first deposited onto the tip of the scanning tunneling microscope, which then acted as a reservoir from which copper could be transferred to the surface during an appropriate approach of the tip to the surface. Tip approach and position were controlled externally by a microprocessor unit, allowing the fabrication of various patterns, cluster arrays, and "conducting wires" in a very flexible and convenient manner.

Abstract
As a result of a sociological-oriented noise study in the city of Erfurt specific intracity noise problems are analysed via their effects. The authors deal with the expectation of calm of people living in different areas of the city, with the relevance of effect of the two usual evaluation levels Leq and Lmax for noise by running traffic, with noise decrease by sound attenuation improvements, and with the subjective and objective evaluation of an industrial front ventilation element. Moreover, the effects of traffic noise on inhabitants before and after significant traffic reduction are shown.

Abstract
Interpreting a sociological study in the city of Erfurt the results of a written interrogation of noise annoyance of a representative random sample of inhabitants are shown and selected characteristics both of the annoyed and the nonannoyed inhabitants are compared. From noise level measurements a proposal for a traffic noise threshold limit has been derived that corresponds to the requirement for calm. Moreover, moderators have been investigated which interfere with the degree of annoyance; health complaints of both groups of the interrogated individuals were compared. It could be shown, that a written interrogation of inhabitants of a territory is able to deliver sufficiently exact information concerning noise annoyance.

Abstract
Several big agricultural fermentation plants for producing of "biogas" are in operation in the GDR. Problems of distances to other objects, utilisation of methane and storage of liquid manure (slurry) are discussed. Some results of experiments about the immissions in the environment are demonstrated. They have point out, that the emissions of microorganisms and viruses cannot be demonstrated in a distance of more than about 200 meters. It is the most important hygienic acknowledge, that the distance of organoleptic observation is always greater than the epidemiologic or sanitary one. Therefore the production of energy by anaerobic fermentation of liquid manure and sewage sludge seems to be an useful way from hygienic point of view.

Abstract
Annually in the district Erfurt 7 percent of all reported diarrhoeal illnesses were microbiologically identified. Salmonellosis, shigellosis and Campylobacter infections dominate. Between 1986 and 1987 a strong increase of salmonellosis were registered, which was caused by S. enteritidis in 70% of the cases and associated with the consumption of eggs or other products, which were manufactured from eggs contaminated with S. enteritidis.
