DBASS3 and DBASS5: databases of aberrant 3'- and 5'-splice sites

Buratti, Emanuele, Chivers, Martin, Hwang, Gyulin and Vorechovsky, Igor (2011) DBASS3 and DBASS5: databases of aberrant 3'- and 5'-splice sites Nucleic Acids Research, 39, (Supplement 1), D86-D91. (doi:10.1093/nar/gkq887). (PMID:20929868).

DBASS3 and DBASS5 provide comprehensive repositories of new exon boundaries that were induced by pathogenic mutations in human disease genes. Aberrant 5?- and 3?-splice sites were activated either by mutations in the consensus sequences of natural exon–intron junctions (cryptic sites) or elsewhere (‘de novo’ sites). DBASS3 and DBASS5 currently contain approximately 900 records of cryptic and de novo 3?- and 5?-splice sites that were produced by over a thousand different mutations in approximately 360 genes. DBASS3 and DBASS5 data 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 can also retrieve reference sequences of both aberrant and authentic splice sites with the underlying mutation. These data will facilitate identification of introns or exons frequently involved in aberrant splicing, mutation analysis of human disease genes and study of germline or somatic mutations that impair RNA processing. Finally, this resource will be useful for fine-tuning splice-site prediction algorithms, better definition of auxiliary splicing signals and design of new reporter assays.
