Nucleotide and deduced amino acid sequences ofTFG-ALK cDNA in short TFG-ALK_S (A) and long TFG-ALK_L (B) forms. (A) Nucleotide sequence was numbered according to the previously described sequences. The putative coiled-coil domain of the TFG sequence is underlined. The asterisk marks a previously undescribed polymorphism (gtc → atc; Val → Ile). The translocation breakpoint in the cDNA is marked with an arrow. (B) The additional 165 bp TFG sequence is underlined. The translocation breakpoint in the cDNA is marked with an arrow.
