  1. Five prediction programs were used: Splice Site Finder (SSF), MaxEntScan (MES), NNsplice (NNS), GeneSplicer (GS), and Human Splicing Finder (HSF). The thresholds represent score predicted for wt sequence/score predicted for mutated sequence. Scores indicate the values for SD or SA sites, respectively. Changes relative to wild type sequences are indicated in % (bold if >10%). IVS = intron; NI = not identified.
