Long interspersed nuclear element-1 (LINE-1 or L1) is a type of retrotransposon that comprise around 17% of the human genome. Increasing evidence has suggested that L1 activity, termed as L1 retrotransposition, may occur in somatic cells such as neural progenitor cells (NPC) in higher rate than other non-brain tissues. Indeed, L1 retrotransposition has been found to be associated with several types of neurological disorders. Thus, L1 activity may contribute to the mosaicism in brain tissues, suggesting an intriguing, and also important role of L1 in the central nervous system.
