The human genome is by far the largest genome to be sequenced, and its size and complexity present many challenges for sequence assembly. The International Human Genome Sequencing Consortium constructed a map of the whole genome to enable the selection of clones for sequencing and for the accurate assembly of the genome sequence. Here we report the(More)
Pancreatic carcinomas with acinar differentiation, including acinar cell carcinoma, pancreatoblastoma and carcinomas with mixed differentiation, are distinct pancreatic neoplasms with poor prognosis. Although recent whole-exome sequencing analyses have defined the somatic mutations that characterize the other major neoplasms of the pancreas, the molecular(More)
We have placed 7,600 cytogenetically defined landmarks on the draft sequence of the human genome to help with the characterization of genes altered by gross chromosomal aberrations that cause human disease. The landmarks are large-insert clones mapped to chromosome bands by fluorescence in situ hybridization. Each clone contains a sequence tag that is(More)
The cDNA for the fifth mammalian aquaporin (AQP5) was isolated from rat, and expression was demonstrated in rat salivary and lacrimal glands, cornea, and lung (Raina, S., Preston, G. M., Guggino, W. B., and Agre, P. (1995) J. Biol. Chem. 270, 1908-1912). Here we report the isolation and characterization of the human AQP5 cDNA and gene. The AQP5 cDNA from a(More)
Acinic cell carcinoma (ACC) is a low-grade salivary gland malignancy characterized by serous acinar differentiation. Most ACCs arise in the parotid gland, but ACCs have been reported to originate in nonparotid salivary glands where serous acini are less abundant. Given the recent discovery of mammary analog secretory carcinoma (MASC)-a salivary malignancy(More)
A subset of renal cell carcinomas (RCCs) is characterized by t(6;11)(p21;q12), which results in fusion of the untranslated Alpha (MALAT1) gene to the TFEB gene. Only 21 genetically confirmed cases of t(6;11) RCCs have been reported. This neoplasm typically demonstrates a distinctive biphasic morphology, comprising larger epithelioid cells and smaller cells(More)
Xp11 translocation renal cell carcinomas (RCCs) are characterized by chromosome translocations involving the Xp11.2 breakpoint, resulting in gene fusions involving the TFE3 transcription factor. In archival material, the diagnosis can often be confirmed by TFE3 immunohistochemistry (IHC), but variable fixation (especially prevalent in consultation material)(More)
Deletions of portions of chromosomes 1p and 19q are closely associated with the oligodendroglioma histologic phenotype. In most cases, 1p and 19q are codeleted, yet the mechanism of dual loss is unexplained. We report 5 cases (World Health Organization grade III) in which metaphase cytogenetics identified a derivative chromosome consisting of what appears(More)
GenMapDB (http://genomics.med.upenn.edu/genmapdb) is a repository of human bacterial artificial chromosome (BAC) clones mapped by our laboratory to sequence-tagged site markers. Currently, GenMapDB contains over 3000 mapped clones that span 19 chromosomes, chromosomes 2, 4, 5, 9-22, X and Y. This database provides positional information about human BAC(More)
