  Chromosome Reports Description
In effort to allow the users of the essentially finished sequence viewable at the NCBI and the UCSC Human Genome Browser to evaluate the quality of the human genome sequence, we have created a series of web pages that show comparisons with existing genome-wide sequence tagged sites (STS) maps, BAC end sequence pair information, and clone sequence overlaps. Using this resource, areas in the genome of special research interest can be examined to determine whether the sequence information is accurate and reliable before expensive and time-consuming experiments are undertaken.

The following sequencing centers have primary responsibility for the listed chromosomes:

Sequencing CenterContactChromosomes
Baylor College of MedicineSteve Scherrer 3, 12
Genoscope National Sequencing CentreJean Weissenbach14
Dept. of Energy Joint Genome InstituteJoe Monforte5
Los Alamos National LaboratoryNorman Doggett16
RIKEN Human Genome Research GroupTodd Taylor 11, 21 (21 consortium)
Sanger CentreJane Rogers1, 6, 9, 10, 13, 20, 22, X
Stanford Human Genome CenterJane Grimwood19
Washington University Genome Sequencing CenterRick Wilson2, 4, 7, Y
Whitehead InstituteChad Nausbaum8, 15, 17, 18

More information about the sequencing effort can be found at Ensembl's Human Assemblies Genome Server and NCBI's Human Genome Sequencing web sites.

Each center is responsible for producing a complete recipe (agp file) composed of accessioned sequences for their chromosome(s). All of the sequence contained in the ordered and oriented portion of each chromosome is finished sequence.

For the essentially finished sequence, web pages have been created showing how each of these compare with other sources of information. Currently, the user can view the correspondence between the essentially finished sequence and sequence-tagged site STS maps in both a scatter plot and in a tabular format. The STS maps employed in this analysis include the Genethon and Marshfield genetic maps, the Whitehead Institute YAC map, and the NCBI GeneMap99 GB4 and G3, Whitehead Institute, and Stanford TNG radiation hybridization (RH) maps. In addition, there is BAC End Pairs and Clone Overlap information. A Summary Page is provided that shows a high-level view of all of this information for each chromosome. Multiple sources of information are used because each has errors. With this combination, it can be determined often whether there is an error in one of the chromosome sequences, or if there is a mistake in the conflicting information.

Feedback concerning both these webs pages and the underlying clone maps on which they are based is encouraged. If there appears to be an error in the chromosome sequence, please alert the chromosome coordinator for the corresponding chromosome as listed in the table above. Please include supporting evidence showing why the current sequence is not accurate.

For general comments regarding these web pages, please contact Terry Furey at UC Santa Cruz.
