Abstract excerpt
Genomic variations with no apparent effect ("neutral polymorphisms") may have a significant effect on splicing. The effect of this type of mutation is difficult to spot, unless a functional assay is undertaken. In our study, DNA sequencing of a patient with clinically defined neurofibromatosis type 1 (NF1) showed only a single polymorphism in intron 30 due to an A>G transition 279 nucleotides from the 3' splice...
