Automatic sequencing of two aberrant FHIT transcripts. (A) This splice variant was found in normal salivary gland tissue and lacked exons 5–8. (B) This variant was detected in a pleomorphic adenoma and demonstrated replacement of exons 4–8 by a non-coding sequence of 46 bp identified in intron 5. The insertion shifted the reading frame and introduced a premature stop codon at the beginning of exon 9.
