PCR single-strand conformation polymorphism (SSCP) and sequence analyses were performed for identification of structural alterations of the bcl-2 gene in the ORF region corresponding to the 239-amino acid p26-bcl-2 alpha protein.     ///    They also show that transformation of FL cells may be associated with somatic point mutations of the bcl-2 proto-oncogene ORF sequence resulting in alteration of the p26-bcl-2 alpha gene product..
