  • mRNA positions (Human Genome Variation Society (HGVS) nomenclature), coverage (the number of times an alternate-splicing event was assessed, including multiple assessments of the same sample), detection rates (number of positives divided by the coverage) and methods are indicated.

  • Predominant alternate-splicing events are indicated in bold. Grey boxes indicate a positive detection for alternate-splicing event.

  • BREAST, breast tissue; LCL, lymphoblastoid cell lines; LEU, whole blood leucocytes; PBL, peripheral blood lymphocytes; PBMC, peripheral blood mononuclear cells; QA, qualitative abundance; seq, direct sequencing.
