Abstract
We present the completed dataset and clone repository of the Cancer Chromosome Aberration Project (CCAP), an initiative developed and funded through the intramural program of the U.S. National Cancer Institute, to provide seamless linkage of human cytogenetic markers with the primary nucleotide sequence of the human genome. Spaced at 1-2 Mb intervals across the human genome, 1,339 bacterial artificial chromosome (BAC) clones have been localized to chromosomal bands through high-resolution fluorescence in situ hybridization (FISH) mapping. Of these clones, 99.8% can be positioned on the primary human genome sequence and 95% are placed at or close to their precise nucleotide starts and stops. This dataset can be studied and manipulated within generally available public Web sites. The clones are available from a commercial repository. The CCAP BAC clone set provides anchors for the interrogation of gene and sequence involvement in oncogenic and developmental disorders when the starting point is the recognition of a structural, numerical, or interstitial chromosomal aberration. This dataset also provides a current view of the quality and coherence of the available genome sequence and insight into the nucleotide and three-dimensional structures that manifest as Giemsa light and dark chromosomal banding patterns.

Abstract
The redundancy of sequences in dbEST has approached a level where contiguous cDNA sequences of genes can be assembled, without the need to physically handle the clones from which the ESTs are derived. This is termed EST based in silico gene cloning. With the availability of sequence chromatogram files for a subset of ESTs, the quality of EST sequences can be ascertained accurately and used in contig assembly. In this report, we performed a study using this approach and isolated five novel human genes, C11orf1-C11orf5, in the 11q13-q22 region. The full open reading frames of these genes were determined by comparison with their orthologs, of which four mouse orthologs were isolated (c11orf1, c11orf2, c11orf3 and c11orf5). These genes were then analyzed using several proteomics tools. Both C11orf1 and C11orf2 are nuclear proteins with no other distinguishing features. C11orf3 is a cytoplasmic protein containing an ATP/GTP binding site, a signal peptide located in the N-terminus and a similarity to the C. elegans protein "Probable ARP 2/3 complex 20kD subunit." C11orf4 is a peptide which displays four putative transmembrane domains and is predicted to have a cytoplasmic localization. It contains signal peptides at the N- and C-termini. C11orf5 is a putative nuclear protein displaying a central coiled coil domain. Here, we propose that this purely EST-based cloning approach can be used by modestly sized laboratories to rapidly and accurately characterize and map a significant number of human genes without the need of further sequencing.

Abstract
Prostate-specific membrane antigen (PSMA) is a 100 kDa type II transmembrane protein with folate hydrolase and NAALAdase activity. PSMA is highly expressed in prostate cancer and the vasculature of most solid tumors, and is currently the target of a number of diagnostic and therapeutic strategies. PSMA is also expressed in the brain, and is involved in conversion of the major neurotransmitter NAAG (N-acetyl-aspartyl glutamate) to NAA and free glutamate, the levels of which are disrupted in several neurological disorders including multiple sclerosis, amyotrophic lateral sclerosis, Alzheimer's disease and schizophrenia. To facilitate analysis of the role of PSMA in carcinoma we have determined the structural organization of the gene. The gene consists of 19 exons spanning approximately 60 kb of genomic DNA. A 1244 nt portion of the 5' region of the PSMA gene was able to drive the firefly luciferase reporter gene in prostate but not breast-derived cell lines. We have mapped the gene encoding PSMA to 11p11-p12, however a gene homologous, but not identical, to PSMA exists on chromosome 11q14. Analysis of sequence differences between non-coding regions of the two genes suggests duplication and divergence occurred 22 million years ago.

Abstract
The genes responsible for hereditary paragangliomas (glomus tumors, MIM No. 168000) have been mapped to two distinct loci on the long arm of chromosome 11. Most of the informative families appear to be linked to the distal locus on chromosome 11q23 (PGL1), which has been previously confined to a 2-cM interval by haplotype analysis in an extended Dutch pedigree. To facilitate the identification of the PGL1 disease gene, we constructed an approximately 4-Mb ordered clone contig map of Sequence tagged sites, expressed sequence tags (ESTs), and known genes that spans the PGL1 critical region on chromosome 11q23. Among 29 new positional candidate ESTs, only two (EST100999 and EST241777) mapped within the PGL1 critical region. We further characterized the genomic organization of the promyelocytic leukemia zinc finger (PLZF) gene that maps within the PGL1 critical region and physically excluded the serotonin receptor type 3 (5HT3R) gene. Finally, we identified a common, silent, single-base substitution polymorphism in the 5HT3R gene and characterized the allele sets of two new highly polymorphic microsatellite repeats within the PGL1 critical region.

Abstract
Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant disorder that results in parathyroid, anterior pituitary, and pancreatic and duodenal endocrine tumors in affected individuals. The MEN1 locus is tightly linked to the marker PYGM on chromosome 11q13, and linkage analysis has placed the MEN1 gene within a 2-Mb interval flanked by D11S1883 and D11S449. As a step toward cloning the MEN1 gene, we have constructed a 2.8-Mb clone contig consisting of YAC and bacterial clones (PAC, BAC, and P1) for the D11S480 to D11S913 region. The bacterial clones alone represent nearly all of the 2.8-Mb contig. The contig was assembled based on a high-density STS-content analysis of 79 genomic clones (YAC, PAC, BAC, and P1) with 118 STSs. The STSs included 22 polymorphic markers and 20 transcripts, with the remainder primarily derived from the end sequences of the genomic clones. An independent cosmid contig for the 1-Mb PYGM-SEA region was also generated. Support for correctness of the 2.8-Mb contig map comes from an independent ordering of the clones by fiber-FISH. This sequence-ready contig will be a useful resource for positional cloning of MEN1 and other disease genes whose loci fall within this region.

Abstract
Molecular methods that use long-range information to solve genomics problems (i.e., top-down strategies) efficiently have become increasingly prominent in the genomics literature. One such method, an implementation of inner product mapping (IPM), uses noisy, long-range radiation hybrid (RH)/YAC overlap data and relatively noise-free RH/STS overlap data to localize clones to specific chromosomal regions. Because the molecular data are rarely noise-free, statistical models tailored to the top-down molecular methods make the methods far more effective. We develop two statistical models for IPM (or any other top-down strategy of similar form), a parametric logit model and a nonparametric order-restricted model, and show how these models can be implemented within a hierarchical Bayes framework. Using these models, we refine the chromosome 11 map reported in M. Perlin et al. (1995, Genomics 28: 315-327). Our analyses improve the IPM map, both in terms of successful localization of clones and in terms of the confidence with which they are localized.

Abstract
The past few years have been significant advances in our understanding of eukaryotic genomes. In the field of parasitology, this is best exemplified by the application of genome mapping techniques to the study of genome structure and function in the protozoan parasite, Leishmania. Although much is known about the organism and the diseases it causes, molecular genetics has only recently begun to play a major part in elucidating some of the unusual characteristics of this interesting parasite. Mapping of the small (35 Mb) genome and determination of the functional role of genes by the application of in vitro homologous gene targeting techniques are revealing novel avenues for the development of prophylactic measures.

Abstract
We present a radiation hybrid (RH) map of human Chromosome (Chr) X, using 50 markers on 72 radiation hybrids. The markers, obtained from the consensus map, form a grid spanning the entire chromosome. To check the RH map, the marker order was determined by analysis of presence or absence of retained human DNA fragments in the RHs; the comparison with the consensus showed a similar order. Any STSs, microsatellites, genes, and clones can be positioned and ordered relative to the marker grid. This approach integrates genetic, physical, and large-scale clone mapping and is used to link YAC contigs containing data from various experimental sources.
