We performed breakpoint analysis of the transcript expressed by the RCSD1-ABL1 fusion gene.     ///    "RT-PCR and sequence analyses detected transcription of a single RCSD1-ABL1 fusion gene variant, which had breakpoints in exon 3 of RCSD1 and exon 4 of ABL1. "    ///    "The RCSD1 portion of the RCSD1-ABL1 fusion transcript consists of exons 1, 2, and 3. "
