  1. PPH, PolyPhen-2; TIS, Translation Initiation Site; D, Damaging/Probably damaging/Deleterious (SIFT/PPH/PROVEAN); P, Possibly damaging (PPH); N, Tolerated/Benign/Neutral (SIFT/PPH/PROVEAN); WT, Wild type; AS, Acceptor Site; DS, Donor Site; HSF, Human Splicing Finder.
  2. Those variants with concurring results referred as damaging by all of the effect prediction tools of a same category were classified as UV4. The mutations were stated as UV3 when pathogenicity was assessed by two out of the three predictors. Those with neutral or UV2 prognosticated effect were not taken into account as positive results and therefore data for those cases is not shown.
