Table S5. Comparison of co-located ES events among the 26,989 events discovered from the Illumina Human Body Map data and the 25,114 exon skipping (ES) events extracted from the Ensembl v.61 annotations.

All – all events co-located within V bp; Loci – clusters of co-located events (each with a representative ‘anchor’); Var ( =All-Loci) – variations (not including ‘anchors’), representing potential mapping artifacts.
