Abstract
The aim of the present study was to investigate whether chromosome 16p presents breakpoint regions susceptible to radiation-induced rearrangements. The frequencies of translocations were determined by fluorescence in situ hybridization (FISH) using cosmid probes C40 and C55 mapping on chromosome 16p, and a chromosome 16 centromere-specific probe (pHUR195). Peripheral lymphocytes were collected from normal individuals and from seven victims of 137Cs in the Goiania (Brasil) accident (absorbed doses: 0.8-4.6 Gy) 10 years after exposure. In vitro irradiated lymphocytes (3 Gy) were also analyzed. The mean translocation frequency/cell obtained for the 137Cs exposed individuals was 2.4-fold higher than the control value (3.6 x 10(-3) +/- 0.001), and the in vitro irradiated lymphocytes showed a seven-fold increase. The genomic translocation frequencies (FGs) were calculated by the formula Fp = 2.05 fp(1-fp)FG (Lucas et al., 1992). For the irradiated lymphocytes and victims of 137Cs, the FGs calculated on the basis of chromosome 16 were 2- to 8-fold higher than those for chromosomes 1, 4 and 12. Our results indicate that chromosome 16 is more prone to radiation-induced chromosome breaks, and demonstrate a non-random distribution of induced aberrations. This information is valuable for retrospective biological dosimetry in case of human exposure to radiation, since the estimates of absorbed doses are calculated by determining the translocation frequency for a sub-set of chromosomes, and the results are extrapolated to the whole genome, assuming a random distribution of induced aberrations. Furthermore, the demonstration of breakpoints on 16p is compatible with the reports about their involvement in neoplasias.

Abstract
Using a BRCA1 cDNA probe in Southern analysis, we detected a sequence of 348 bp on 4q28 that is homologous to the 3' end of BRCA1. A 28-kb sequence contig has been assembled spanning the homologous region, which we designated BRCA1-h. An open reading frame was identified encoding a sequence of 82 amino acids; 22 of the last 23 amino acids are identical to the last 23 residues of BRCA1. BLAST-searches, RT-PCR and RACE-experiments have been unable to provide evidence that BRCA1-h is part of an expressed gene.

Abstract
Chromosomal region 11q22-q23 is a frequent target for deletion during the development of many solid tumour types, including breast, ovary, cervix, stomach, bladder carcinomas and melanoma. One of the most commonly deleted subregions contains the SDHD gene, which encodes the small subunit of cytochrome b (cybS) in mitochondrial complex II (succinate-ubiquinone oxidoreductase). Germline mutations in SDHD cause hereditary paraganglioma type 1 (PGL1), and suggest a tumour suppressor role for cybS. We present a high-resolution physical map spanning SDHD, covered by 19 YACs and 20 BACs. An approximate 1.1-Mb gene-rich region around SDHD is spanned by a complete BAC contig. Twenty-six new STSs are developed from the BAC clone ends. In addition to the discovery and characterisation of 15 new simple tandem repeat polymorphisms, we provide integrated positional information for 33 ESTs and known genes, including KIAA1391, POU2AF1 (OBF1), PPP2R1B, CRYAB, HSPB2, DLAT, IL-18, PTPS, KIAA0781 and KAIA4591, which is mapped by NotI site cloning. We describe full-length transcript sequence for PPP2R1B, encoding the protein phosphatase 2A regulatory subunit A beta isoform. We also discover a processed pseudogene for USA-CYP, a cyclophilin associated with U4/U6 snRPNs, and a novel gene, DDP2, encoding a mitochondrial protein similar to the X-linked deafness-dystonia protein, which is juxtaposed 5'-to-5' to SDHD. This map will help assess this gene-rich region in PGL and in other common tumours.

Abstract
Most reported microdeletions of the CREB-binding protein (CBP) gene in the Rubinstein-Taybi syndrome (RTS) were detected by fluorescence in situ hybridization (FISH) with a single cosmid probe specific to the 3' region of the gene. In order to test the hypothesis that the rate of microdeletion-positive cases would be greater if the entire gene was evaluated, we performed FISH on 66 patients with an established diagnosis of RTS, using a panel of five cosmids that span the CBP gene. Five of 66 patients had deletions by FISH (9%), consistent with those rates reported in various series that ranged between 3-25%. Among our cases, different deletions were observed; one was deleted for the 5' but not the 3' region of the CBP gene (case 055). Other deletions included a total CBP deletion extending from the 5' through the 3' region (case 017), a deletion of all but the 5' region (cases 006 and 060), and an interstitial deletion in the 3' region (case 028). Fine breakpoint mapping with additional cosmid and yeast artificial chromosome (YAC) constructs was performed on these patients. The findings of a partial 5' deletion and of interstitial deletions of the CBP gene add to the known spectrum of mutations of this gene in RTS and demonstrate the need for evaluation of the entire CBP gene region for deletions rather than only the 3' region in RTS patients. These results further suggest that the true rate of microdeletion across the CBP gene detectable by FISH has yet to be established firmly. No phenotypic differences between partial deletion, complete deletion, and nondeletion patients were observed, supporting a haploinsufficiency model for RSTS.

Abstract
The CREB-binding protein (CBP) is a large nuclear protein that regulates many signal transduction pathways and is involved in chromatin-mediated transcription. The translocation t(8;16)(p11;p13.3) consistently disrupts two genes: the CBP gene on chromosome band 16p13.3 and the MOZ gene on chromosome band 8p11. Although a fusion of these two genes as a result of the translocation is expected, attempts at detecting the fusion transcript by reverse transcriptase polymerase chain reaction (RT-PCR) have proven difficult; to date, only one in-frame CBP/MOZ fusion transcript has been reported. We therefore sought other reliable means of detecting CBP rearrangements. We applied fluorescence in situ hybridization (FISH) and Southern blot analyses to a series of AML patients with a t(8;16) and detected DNA rearrangements of both the CBP and the MOZ loci in all cases tested. All six cases examined for CBP rearrangements have breakpoints within a 13 kb breakpoint cluster region at the 5' end of the CBP gene. Additionally, we used a MOZ cDNA probe to construct a surrounding cosmid contig and detect DNA rearrangements in three t(8;16) cases, all of which display rearrangements within a 6 kb genomic fragment of the MOZ gene. We have thus developed a series of cosmid probes that consistently detect the disruption of the CBP gene in t(8;16) patients. These clones could potentially be used to screen other cancer-associated or congenital translocations involving chromosome band 16p13.3 as well.

Abstract
The pericentric inversion on chromosome 16 [inv(16)(p13q22)] and related t(16;16)(p13;q22) are recurrent aberrations associated with acute myeloid leukemia (AML) M4 Eo. Both abberations result in a fusion of the core binding factor beta (CBFB) and smooth muscle myosin heavy chain gene (MYH11). A selected genomic 6.9-kb BamHl probe detects MYH11 DNA rearrangements in 18 of 19 inv(16)/t(16;16) patients tested using HindIII digested DNA. The rearranged fragments were not detectable after remission in two cases tested, while they were present after relapse in one of these two cases tested.

Abstract
A YAC clone that contains the human gene NFKB3, encoding the p65 subunit of transcription factor nuclear factor kappa B (NF-kappa B), was isolated. The YAC contains the entire NFKB3 gene, which is smaller than 15 kb and present in a single copy in the genome. Fluorescence in situ hybridization with metaphase chromosomes showed two different chromosomal locations (11q12 and Xp11.4) for sequences present in the YAC. The NFKB3 gene was assigned to chromosome 11q12 by PCR analysis of a panel of relevant hybrid cell lines. Thus, no linkage exists between NFKB3 and genes encoding other known members of the NF-kappa B family.

Abstract
Chromosome 16 aberrations are well known in acute nonlymphocytic leukemia (ANLL). The most frequent chromosome 16 aberration in ANLL subtype M4Eo is the inv(16)(p13q22). Recently, we showed that in 5 inv(16) patients with ANLL M4Eo the short arm breakpoints are clustered within a 14-kb genomic EcoRI fragment. We report here the identification of a gene situated in the 14-kb fragment. The gene, which codes for a myosin peptide, is disrupted by the inversion of chromosome 16 in the 5 patients. To the best of our knowledge, this is the first report of a myosin gene disrupted in leukemia.

Abstract
A de novo duplication of the proximal part of the long arms of chromosome 5 was found in a male born with craniostenosis, ear tags and kidney dysplasia. The nature of the chromosomal aberration was defined by fluorescence in situ hybridization and the origin of the duplication was traced by polymorphic DNA markers. A comparison is made with the published cases showing similar duplications in the long arm of chromosome 5.

Abstract
The pericentric inversion of chromosome 16 and the t(16;16) are two recurrent aberrations in bone marrow of patients with acute nonlymphocytic leukemia subtype M4 Eo, characterized by abnormal eosinophilic granulation. We describe here the precise localization of the breakpoints using fluorescence in situ hybridization (FISH) with cosmids spread over the short arm of chromosome 16 and the detection, isolation and characterization of a 14Kb EcoRI fragment containing a cluster of breakpoints. First, cosmids were mapped to intervals defined by constitutional 16p rearrangements, second, the inv(16) and t(16;16) breakpoints were mapped to one of the intervals using FISH with the mapped cosmids and third, cosmids within this interval were ordered using two color interphase FISH. An STS of the cosmid closest to the breakpoints was then used to isolate five YACs, which did span all of the 16 inv(16) breakpoints and one t(16;16) breakpoint analysed. In the DNA of one inv(16) patient we detected an additional submicroscopic deletion immediately proximal to the 16p breakpoint. Since this patient has the same phenotype, the 16p sequences proximal to the breakpoint seem non-essential to M4 Eo. This implies that the pathologic event is the juxtaposition of sequences distal to the 16p breakpoint with sequences proximal to the 16q breakpoint. While four of the five YACs showed instability of the region around the inv(16) breakpoint, DNA halo analysis allowed us to identify one YAC which was co-linear with normal genomic DNA and has yielded the actual breakpoint sequences which could be subcloned into cosmids and fosmids.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Yeast artificial chromosomes (YACs) of 340 and 370 kb that contain the functional human glutamate dehydrogenase gene (GLUD1) and the pseudogene GLUDP2, respectively, were isolated. These genes were not physically linked to each other nor to any other sequences homologous to the exons of GLUD1. No additional GLUD sequences were found within at least 70 kb of the 5' and 175 kb of the 3' end of GLUD1 or 150 kb of either end of GLUDP2. By in situ hybridization, GLUD1 was located at 10q23.3, GLUDP2 at 10q11.2, and another pseudogene of the GLUD gene family, GLUDP3, at 10q22.1. DNA fragments of these three genes showed cross-hybridization to the loci assigned to the other two genes, but not to any other chromosomal locus. Thus, these three genes are located at distinct positions on chromosome 10q.

Abstract
We have previously described a series of patients in whom the deletion of 1-2 megabases (Mb) of DNA from the tip of the short arm of chromosome 16 (band 16p13.3) is associated with alpha-thalassemia/mental retardation syndrome (ATR-16). We now show that one of these patients has a de novo truncation of the terminal 2 Mb of chromosome 16p and that telomeric sequence (TTAGGG)n has been added at the site of breakage. This suggests that the chromosomal break, which is paternal in origin and which probably arose at meiosis, has been stabilized in vivo by the direct addition of the telomeric sequence. Sequence comparisons of this breakpoint with that of a previously described chromosomal truncation (alpha alpha)TI do not reveal extensive sequence homology. However, both breakpoints show minimal complementarity (3-4 bp) to the proposed RNA template of human telomerase at the site at which telomere repeats have been added. Unlike previously characterized individuals with ATR-16, the clinical features of this patient appear to be solely due to monosomy for the terminal portion of 16p13.3. The identification of further patients with "pure" monosomy for the tip of chromosome 16p will be important for defining the loci contributing to the phenotype of this syndrome.

Abstract
To improve DNA resolution of fluorescence in situ hybridization we have adapted a nuclear extraction technique, resulting in highly extended DNA loops arranged around the nuclear matrix in a halo-like structure. In situ hybridization signals from alphoid and cosmid DNAs appear as beads-on-a-string, which, according to preliminary experiments, results from the association of individual probe fragments. By multicolor hybridizations we have been able to determine relative map position and to easily detect 10 kb overlap between individual cosmid clones, each of which shows linear beaded signals of ca. 10 microns, suggesting that the DNA is essentially linearized in our protocol. The map configuration can be typically derived from analysis of 5-10 cells only. The resolution range of the technique is at least 10-200 kb, and probably as little as a few kb, thus greatly extending the abilities of the existing FISH methodologies. This novel technique is much more efficient and practicable than pronuclei hybridizations, another method for high resolution FISH, and readily produces results with probes of a variety of genomic origin. In conclusion the DNA halo technique should be able to contribute significantly to the assessment of cosmid and YAC overlaps as well as to the sizing of gaps between adjacent contigs generated in genome projects.

Abstract
Fluorescence in situ hybridization (FISH) is now widely used for the localization of genomic DNA fragments, and the identification of chromosomes by painting. We now show that half of the chromosomal complement can be painted in twelve different colors by using human chromosome specific libraries carrying three distinct labels mixed in multiple ratios. The photographs are in 'real' color rather than 'colorized'. The painting technique described here can be used for the identification of small or complex chromosomal rearrangements and marker chromosomes in humans or in any other species for which well defined chromosome specific libraries exist in a laboratory equipped with a conventional fluorescence microscope. The versatility of this novel cytogenetic technology may well constitute an advancement comparable to the introduction of chromosome banding and high resolution analysis of chromosomes in prometaphase.

Abstract
The human dystrophin gene, mutations of which cause Duchenne and Becker muscular dystrophy, measures 2.4 Mb. This size seriously limits its cloning as a single DNA fragment and subsequent in-vitro expression studies. We have used stepwise in-vivo recombination between overlapping yeast artificial chromosomes (YACs) to reconstruct the dystrophin gene. The recombinant YACs are mitotically stable upon propagation in haploid yeast cells. In contrast, specific combinations of YACs display a remarkable mitotic and meiotic instability in diploid cells. Non-disjunction is rare for overlapping YACs, but increases upon sporulation of diploid cells containing non-overlapping molecules. We have exploited this feature in a three-point recombination to bridge a 280 kb gap between two non-overlapping YACs for which no YAC of proper polarity existed. Our largest recombinant YAC measures 2.3 Mb and contains the entire muscle specific DMD-gene with the exception of a 100 kb region containing the in-frame exon 60. The latter segment has a high tendency to undergo deletions in multi-molecular interactions, probably due to the presence of as yet unidentified instability-enhancing sequences. Fluorescent in situ hybridizations confirmed that the 2.3 Mb DMD YAC contained Xp21-sequences only and indicated a compact tertiary structure of the DMD-gene in interphase lymphocyte nuclei. We conclude that the yeast system is a flexible, efficient and generally applicable tool to reconstruct or build genomic regions from overlapping YAC constituents. Its application to the human dystrophin gene has provided many possibilities for future studies.

Abstract
Specific rearrangements of chromosome 16 are well known in acute nonlymphocytic leukemia with abnormal eosinophils. While mapping cosmids relative to breakpoints in chromosome 16 in leukemic cells with fluorescence in situ hybridization (FISH), we have identified three areas of extensive cross-homology between 16p and 16q. Three cosmids among 99 tested showed two large signals on the short arm and one signal on the long arm of chromosome 16. A fourth cosmid showed mainly two signals on the short arm. With the 16p-specific cosmid we can demonstrate that the breakpoints of a pericentric inversion and a reciprocal (16;16) translocation, both of which are characteristic for acute leukemia, map to the most distal of two blocks on the short arm. We suggest that there may be at least two distinct repetitive elements specific for chromosome 16 interdigitated on 16p. The presence of a similar repeat in the short, as well as the long arm of the chromosome, may play a role in the origin of chromosome 16 rearrangements in acute leukemia.

Abstract
A yeast artificial chromosome (YAC) library has been constructed from a somatic cell hybrid containing a t(1p;19q) chromosome and chromosome 17. After amplification, part of this library was analyzed by high-density colony filter screening with a repetitive human DNA probe (Alu). The human YACs distinguished by the screening were further analyzed by Alu fingerprinting and Alu PCR. Fluorescent in situ hybridization (FISH) was performed to localize the YACs to subchromosomal regions of chromosome 1p, 17, or 19q. We have obtained a panel of 123 individual YACs with a mean size of 160 kb, and 77 of these were regionally localized by FISH: 33 to 1p, 10 to 17p, 25 to 17q, and 9 to 19q. The YACs cover a total of 19.7 Mb or 9% of the 220 Mb of human DNA contained in the hybrid. No overlapping YACs have yet been detected. These YACs are available upon request and should be helpful in mapping studies of disease loci, e.g., Charcot-Marie-Tooth disease, Miller-Dieker syndrome, hereditary breast tumor, myotonic dystrophy, and malignant hyperthermia.

Abstract
Chromosome aberrations of a hypodiploid ovarian carcinoma cell line (modal chromosome number 38) having a complex karyotype were analyzed using biotinylated DNA library probes that specifically hybridize to chromosomes 3, 6, 7, 8, 11, 13, and 16 from telomere (pter) to telomere (qter). A series of cosmid probes localized to the short arm of chromosome 16 were used to further investigate one of the two aberrant chromosomes 16 present in this cell line. The competitive in situ suppression (CISS) hybridization of DNA-libraries was mostly performed subsequent to GTG-banding of the same metaphase cell in order to interpret the hybridization signals optimally. This combined approach made it possible to detect the origin of chromosomal material that could not be identified using GTG-banding. Furthermore, the in situ hybridization techniques appeared to be helpful in the characterization of complex translocations and for accurate breakpoint determination.

Abstract
We report a case of acute nonlymphocytic leukemia (ANLL) M5 with the characteristic t(8;16)(p11;p13). The breakpoint in the short arm was regionally localized using nonradioactive in situ hybridization with a series of cosmids of chromosome 16. The results show that a difference exists between the breakpoint in chromosome 16(p13) in this t(8;16) and the breakpoint involved in the short arm in the characteristic inversion 16 (p13;q22)) that occurs in ANLL M4eo. Two different loci appear to be involved in these chromosomal rearrangements.

Abstract
In order to develop a suitable mammalian expression system for human insulin-like growth factors (hIGFs) and mutant IGFs, we have constructed several artificial IGF genes, based on a cDNA encoding the IGF-I precursor (153 amino acids). Transient expression experiments using mouse Ltk- cells revealed that the IGF-I gene constructs were efficiently expressed when placed under control of the SV40 Early promoter (SV40E). This resulted in the synthesis and secretion of IGF-I receptor-reactive products. Constructs encoding an IGF-I precursor with a truncated signal peptide of 25 amino acids under control of SV40E promoter or the inducible Drosophila heat shock hsp70 promoter, were used to establish stably transformed CHOdhfr- and mouse L cells. Clones secreting IGF-I were identified by an IGF-I-specific radioreceptor assay. Immunoblot analysis of conditioned media from these clones resulted in the specific precipitation of a protein of 7 kDa identical in size to native IGF-I purified from human serum. After optimization of the expression conditions, the stable cell lines secrete 0.5-2 microgram/10(6) cells of IGF-I. The biological activity of the secreted recombinant IGF-I was shown by its ability to stimulate DNA synthesis in human MCF-7 cells. The results described in this paper indicate that a mammalian expression system, employing CHOdhfr- or L cells, is a useful system for the synthesis of biological active IGF-I.

Abstract
Polymorphic DNA markers can now be used for presymptomatic and prenatal diagnosis of the autosomal dominant form of polycystic kidney disease (PKD). A detailed map is known for the chromosomal region around the PKD1 gene on the short arm of chromosome 16. We present here a simple, two step procedure for diagnosis of PKD1 by family studies. Using this approach, at least 92% of random subjects are informative for polymorphic DNA markers bracketing the PKD1 gene. The recombination rate between these flanking markers is on average 10%. In non-recombinants (90% of family members), the accuracy of diagnosis using DNA markers is greater than 99%. We conclude that sufficient well defined DNA markers are now available for routine diagnosis of PKD1. We recommend, however, that prenatal diagnosis of PKD by chorionic villi sampling should be attempted only after the linkage phase of the DNA markers has been established by haplotyping the index family. Since autosomal dominant PKD has been found to be genetically heterogeneous, families should be of sufficient size to rule out the rare form of PKD not caused by a mutation on the short arm of chromosome 16.

Abstract
To define the PKD1 locus further, the gene involved in the most frequent form of adult polycystic kidney disease, probes from 16 polymorphic loci were mapped on 16p13.1-pter with the combined use of cell lines containing rearranged chromosomes and family studies. Five breakpoints in the distal part of 16p arbitrarily subdivided the loci into five groups. By analysing 58 recombination events among 259 informative meioses in 12 large families with PKD, we were able to construct a linkage map for the distal part of 16p. The order of the markers obtained with chromosomal rearrangements was confirmed by the family studies. The D16S85 locus near alpha globin, D16S21, and D16S83 map distal, or telomeric, to PKD1. The polymorphic red cell enzyme phosphoglycolate phosphatase (PGP), D16S84, D16S259, and D16S246 showed no recombination with PKD1. The remaining nine RFLPs all map proximal to the PKD1 gene. By cosmid walking, additional RFLPs were detected at the D16S21 locus. A single intrahaplotype recombination observed defines the orientation of D16S21 relative to PKD1. The new polymorphisms are valuable for presymptomatic and prenatal diagnosis of PKD1. Furthermore, our map is both a good starting point for the physical map of 16p and a useful tool for the isolation of the PKD1 gene.

Abstract
The pericentric inversion of chromosome 16 characteristic for acute nonlymphocytic leukemia, subtype M4, was detected in five patients by means of nonradioactive in situ hybridization of complete cosmids. First, five cosmids situated along the short arm of chromosome 16 were used to map the breakpoint of the inversion distal to the rare folate-sensitive fragile site FRA16A. Then, the use of two cosmids on either side of the breakpoint, combined with a probe specific for the centromeric region of chromosome 16, readily detected the inversion, even in poor metaphase spreads.

Abstract
A rapid method for localizing large numbers of complete cosmids by nonradioactive in situ hybridization is described. The cosmids are nick translated in the presence of biotin-16-dUTP, incubated with an excess of sonicated human DNA, and used as a probe for in situ hybridization. Sites of hybridization are detected by successive treatments with FITC-labeled avidin and biotinylated anti-avidin antibody. Fifty-two cosmids were localized on chromosome 16 in 5 d relative to translocation breakpoints contained in two cell lines. Rapid identification of chromosome 16 was achieved by cohybridization with a chromosome 16-specific centromeric repeat probe.
