MutSpliceDB: a Database of Splice Sites Variants

Developed by: Computational and Systems Biology Branch
(Biometric Research Program, DCTD/NCI)

MutSpliceDB documents mutation effect(s) on splicing (such as exon inclusion/exclusion or intron retention) based on RNA-seq BAM files from sample(s) with particular splice site mutations.
The research community can propose additional splice site mutations for inclusion in this public resource when RNA-seq based evidence is available.

*Disclaimer*: MutSpliceDB is a free resource intended for research purposes only. It should NOT be used for emergencies or medical or professional advice.
