Genome-wide detection of human intronic AG-gain variants in BP-ACC region

Human variants that introduce an AG in the intronic region between the branchpoint (BP) and the canonical splice acceptor site (ACC) can disrupt pre-mRNA splicing and result in misspliced gene products.
 
Based on our previously developed BPHunter, we delineate the BP-ACC segments of all human introns of protein-coding genes, for the first time. We find an extreme depletion of AG/YAG in the high-risk [BP+8, ACC-4] region.
 
AGAIN is a genome-wide approach to pinpoint intronic AG-gain variants (SNVs, insertions, deletions) in the BP-ACC region of human genomes. AGAIN also predicts protein-level outcomes resulting from two major missplicing consequences (new acceptor site & complete exon skipping).
