The incidence of one or other rearrangement in chronic myeloid leukemia (CML) patients varies in different reported series. In this study we report the frequencies of BCR-ABL1 fusion transcript variants studied in 43 CML patients from Sudan. The study includes 46 Sudanese patients, three of which negative for the BCR-ABL1 fusion transcript. More than half of 43 positive patients showed b2a2 fusion transcript (53.5%), while (41.9%) showed b3a2 transcript and the remaining (4.6%) coexpression of b3a2/ b2a2 and b3a2/b2a2/e19a2. We detected neither coexpression of p210/p190 nor e1a2 alone. Male patients showed a tendency to express b2a2, while female tende to express b3a2 (p = 0.017). Moreover, a single nucleotide polymorphism was detected in BCR exon 13 in...

An analysis of multiplex-PCR in the detection of BCR-ABL transcripts in hematological disorders
Provedor de dados: Genetics and Molecular Biology
Autores: Sastre,Darío A.; Argaraña,Carlos E.; Heller,Viviana B.; Gallo,Mónica; Fernández,Enrique N.; Rodríguez,Cecilia M.
In this work, we describe the advantages of multiplex-PCR in the specific detection of BCR-ABL transcripts in different hematological disorders and its sensitivity compared to nested PCR. Fifty-three patients were studied for the presence of BCR-ABL transcripts: 24 patients with chronic myeloid leukemia (CML), 20 with acute leukemia (AL), and 9 patients with other hematological disorders. A variant rearrangement (b3a3) was found in a single case of CML (4.2%). Four out of the 20 patients with AL (20.0%) (14 adults, 6 children) were bcr-abl(+), and in this group three cases were classified as B-acute lymphoblastic leukemia (B-ALL), and one as acute myeloblastic leukemia (AML). Two of the three patients with B-ALL were positive for b2a2 and the other one for...
