A-to-I RNA editing sites with the frequency of editing above 1% in three sets of normal human samples.

aGenomic position is the position in human genomic database from UCSC (http://genome.ucsc.edu, hg18 version, March 2006 assembly).bFrequency of RNA editing is presented as the percentage of the total population of transcripts.cReads is the number of transcripts sequenced.d11 new RNA editing sites identified by Li et al [24].

a) 基因组位点（genomic position）指的是UCSC人类基因组数据库（http://genome.ucsc.edu，hg18版本，2006年3月组装版）中的对应位点。
b) RNA编辑（RNA editing）频率以占总转录本群体的百分比形式呈现。
c) 测序读段（reads）指的是已完成测序的转录本总数量。
d) 本数据集包含Li等人[24]所鉴定的11个全新RNA编辑位点。
