Philadelphia chromosome-negative, bcr/abl-positive chronic myelogenous leukemia.
Chronic myelogenous leukemia(CML)is characterized by the presence of the abnormal chromosome 22, which is termed the Philadelphia chromosome(Ph). The Ph is derived from a translocation between chromosomes 9 and 22, t (9; 22)(q 34; q 11). The c-abl oncogene on the long arm of chromosome 9 fused to the bcr gene on the long arm of chromosome 22 and leads to the formation of a chimeric bcr abl gene...
متن کاملBCR-ABL fusion genes and laboratory findings in patients with chronic myeloid leukemia in northeast Iran
Background: A specific chromosomal abnormality, the Philadelphia chromosome (BCR-ABL fusion), is present in all patients with chronic myeloid leukemia (CML). The b2a2 and b3a2 fusion mRNAs encode p210 fusion protein p210 and e1a2 encode p190. The aim of this study was to evaluate the frequency of BCR-ABL fusion transcript variants in Northeast of Iranian CML patients and to compare the laborato...
متن کاملFrequency of BCR-ABL Fusion Transcripts in Iranian Azeri Turkish patients with Chronic Myeloid Leukemia
Background: The Philadelphia chromosome (Ph) characterized by t (9; 22) (q34; q11.2) is a reciprocal translocation giving rise to a chimeric BCR-ABL fusion gene. Incidence of Ph chromosome is over 98% in Patients with Chronic Myeloid Leukemia (CML) and around 20% in acute lymphoblastic leukemia (ALL). The finding of this fusion gene is essential for diagnosis of CML by detection of various fusi...
متن کاملRearrangement of the bcr gene in Philadelphia chromosome-negative chronic myeloid leukemia.
We studied the clinical, hematologic, cytogenetic, and molecular biologic features of seven patients with Philadelphia (Ph1) chromosome-negative chronic myeloid leukemia (CML). In five cases the hematologic findings were indistinguishable from those of patients with classical Ph1-positive disease. Myeloid cells were studied by chromosome-banding techniques. One patient had a masked Ph1 chromoso...
متن کاملPhiladelphia-negative chromosomal evolution during treatment for chronic myeloid leukemia.
Chromosome evolution is one of the major mechanisms of disease progression and resistance in chronic myeloid leukemia (CML) patients. However, the clinical significance of chromosomal evolution in the Philadelphia (Ph)-negative clone during therapy is not fully understood. We evaluated 94 CML patients in the chronic phase of CML during treatment of the disease. Six of them had Ph-negative ...
