It is concluded that SET-NUP214 fusion gene is often resulted from del(9)(q34).     ///    [Expression of SET-NUP214 fusion gene in patients with T-cell acute lymphoblastic leukemia and its clinical significance]..     ///    RT-PCR was used to detect the expression of SET-NUP214 fusion gene in 58 T-ALL cases.     ///    " This study was aimed to investigate the occurrence and clinical significance of the SET-NUP214 fusion gene in patients with T-cell acute lymphoblastic leukemia (T-ALL), analyse clinical and biological characteristics in this disease. "    ///    The results showed that 6 out of 58 T-ALL cases (10.3%) were detected to have the SET-NUP214 fusion gene by RT-PCR.     ///    PHF6 and NOTCH1 mutations may be potential leukemogenic event in SET-NUP214 fusion gene..     ///    Array-CGH results of 3 SET-NUP214 positive T-ALL patients confirmed that this fusion gene was resulted from a cryptic deletion of 9q34.11q34.13.     ///    "PHF6 and NOTCH1 gene mutations were found in 4 and 5 out of 6 SET-NUP214 positive T-ALL patients, respectively.
