DBASS

• University of Southampton

DBASS is a comprehensive repository of new exon boundaries that were induced by pathogenic mutations in human disease genes. This database consists of two databases, DBASS3 and DBASS5. They provide aberrant 5'- and 3'-splice sites that were activated either by mutations in the consensus sequences of natural exon-intron junctions (cryptic sites) or elsewhere ('de novo' sites). Data in DBASS3 and DBASS5 can be searched by disease phenotype, gene, mutation, location of aberrant splice sites in introns and exons and their distance from authentic counterparts, by bibliographic references and by the splice-site strength estimated with several prediction algorithms. The user is also able to retrieve reference sequences of both aberrant and authentic splice sites with the underlying mutation.
