  1. 1 Exon locations of the F (forward) and R (reverse) PCR primers. 2 Known Alternative Splicing Event As determined from RefSeq, full length mRNAs and ESTs on the UCSC Genome Browser. 3 Relative confidence in the interpretation. 4 Interpretation of the PCR results in terms of transcript structure. 5 Fold change at the gene level. (-) means that the signal is lower in Tumor. Abbreviations: Ex, exon; CE, cassette exon; MEE, mutually exclusive exon; Alt., alternative.
