Research Abstract	We identified an approximately 330-bp sequence inserted into dystrophin gene. This inserted sequence had an approximately 110-bp stretch of T, and complementary sequence of the remaining 212-bp perfectly matched with genomic sequence on the human chromosome 11. Our finding suggested that the source region on chromosome 11 was inserted into dystrophin gene after reverse transcription. Further analysis of the transcript revealed that entire 452-bp region on chromosome 11 was actively transcribed. This 452-bp sequence was transcript from a region where no gene had been mapped and had no appreciable protein coding ability. Thus this transcript is currently considered a novel non-coding gene.
