a Gene symbol of the upstream gene. RefSeq name appears where gene symbol is N/A

b Gene symbol of the downstream gene

c The number of fusion-supporting ESTs found by our computational search

d RT–PCR validation of the existence of the wild-type upstream sequence (having the original termination point). In four of the 20 tested cases, the WT was not detected in the tissues we tested

e RT–PCR validation of the fusion transcript between genes 1 and 2. In case the expression of the fusion was confined to a specific tissue, the tissue name is mentioned in parentheses. No tissue name is mentioned in cases where the expression of the fused transcript was detected in RNAs from multiple tissues
