Ensembl Human What's New v11.31.1 (3 March 2003)

	Ensembl: Latest Developments
	Updated data in v11.31.1    NCBI 31 Ensembl Human release 11.31.1 is built around the NCBI 31 assembly. This assembly has far more finished regions and better gap closure as the human genome approaches "essentially complete" status. The Ensembl gene build process built 24,847 genes containing 37,347 transcripts with many genes showing significant alternative splicing. This new information was principally acquired from more effective use of cDNA data. The gene build has over 95% of known genes represented inside it, with over 50% being identical at the amino acid level, and the rest mostly differing in only one or two positions. Ensembl also provides an transcript-only build, the "EST genes", with a total of 282908 transcripts. This build makes aggressive use of ESTs and contains significant alternative splicing, but also comes with the caveats of using the EST data.    New markers A new marker set has been mapped to the 31 assembly. The set, assembled with the help of Terry Furey from UCSC, is derived from the Genethon, Marshfield, and deCODE genetic maps, the GeneMap99 , G3 and TNG radiation hybrid maps, the Whitehead YAC and RH maps, and NCBI FISH-mapped BAC clones.    New SNPs Ensembl SNP data is now in synch with dbSNP 110.    New comparative data The compara database now contains pairwise homology matches between human, mouse, rat & fugu, as well as synteny data between human, mouse and rat.    New Affymetrix mappings There are now a total of eight Affymetrix chipsets mapped across human, mouse and rat genes. New Features in v11.31.1    Additional synteny display CytoView now displays a track of syntenic regions, allowing easier navigation between homologous regions in different species. [eg...]    Supporting evidence display The display of supporting evidence for exons (found on ExonView) has been redesigned. [more...]    TransView cDNA display TransView can now show cDNA sequence marked up with codons, translations, and SNPs. A dropdown allows you to select how you wish to view the sequence. The lines can also be numbered to allow easy location of a particular region of the sequence. [more...]    MartView updates See the EnsMart homepage for details of Mart updates.
