The analysis of ETV6-NTRK3 fusion transcript. The results of the electrophoresis (a) and direct sequencing (b) revealed the presence of an ETV6-NTRK3 fusion gene. In (a), the arrow indicates the PCR product of the ETV6-NTRK3 transcript. PCR for β-actin and GAPDH was performed as a quality check of the extracted RNA. NC: negative control. L: ladder (molecular marker). In (b), the arrow indicates the fusion point of the ETV6-NTRK3 transcript.
