چکیده

Biphenotypic acute leukemia (BAL) is a subtype of leukemia of ambiguous lineage in the World Health Organization classification system. About one third of the cases have the Philadelphia chromosome, and some cases are associated with other structural abnormalities involving 11q23. BAL is known to have a poor prognosis in both children and adults. According to the previously reported BAL cases with positive BCR-ABL fusion gene, most of the BCR-ABL mRNA transcript type was e1a2. So, we describe here a 30-year-old adult BAL case with the karyotype 46,XY,t(9;22)(q34;q11.2) resulting in a very rare b3a2 type of BCR-ABL mRNA transcript.

BCR-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...

Frequency 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...
