It is becoming increasingly apparent that splicing defects play a key role in cancer, and that genomic changes in splicing elements [1?], sometimes termed “splicing spoilers” [4,5], can promote aberrant splicing. Because regulation of splicing is such a complex network [1,4], all genetic variations in genomic DNA and premRNA should be evaluated for their impact on splicing within any given genomic context. It has been estimated that ,50 of mutations underlying genetic diseases cause aberrant splicing [6]. Alterations in a splicing site or splicing control region can have long range implications for splicing events, including altered 3-D architecture of pre-mRNA, activation of cryptic splice sites, exclusion of exons and/or inclusion of all or part of introns. Single mutations can strengthen otherwise weak splice sites and discriminate against otherwise strong splice sites [2?].
