In addition, an abnormal FISH pattern previously described as the deletion of the 3'BCR region in some BCR/ABL1 positive cases was not proved in our patient.     ///    "A cryptic BCR/ABL1 fusion, which was caused by the insertion of part of the ABL1 gene into the 22q11 region, was proved in HeH clone by FISH, RT-PCR and CGH-SNP array. "    ///    An unusual case of high hyperdiploid childhood ALL with cryptic BCR/ABL1 rearrangement..     ///    "A novel case of extremely rare childhood ALL, characterized by HeH and a cryptic BCR/ABL1 fusion, is presented and to the best of our knowledge described for the first time. "    ///    Here we report a new case of a 17-year-old girl with newly diagnosed ALL and uncommon cytogenetic and clinical finding combining high hyperdiploidy and a cryptic BCR/ABL1 fusion and an inherited Charcot-Marie-Tooth neuropathy detected during the induction treatment.
