  1. Predicted siRNA target sites from siExplorer, siRNA target design and Reynolds et al. (2004) [22] were found to have overlapped regions. Bold indicates the position base preference. '*' indicates the selected siRNA target sites, '1' and '2' indicate the best matches from the blastn search against human transcript and genomic databases respectively. Details of the blastn matches are in additional file 1.
