ABSTRACT
BACKGROUND & OBJECTIVE:
BCR-ABL fusion gene is regarded as the molecular hallmark of chronic myelogenous leukemia (CML), and its expression is controlled by the BCR gene promoter. This study was designed to investigate the polymorphism of the promoter region of BCR gene, and its possible correlation with the disease.METHODS:
A 1.13 kb fragment of BCR gene 5' promotor region was amplified and sequenced from 30 CML patients and 19 controls. Transcription factor binding sites and repeat sequences in this region were analyzed using softwares and online tools.RESULTS:
Four novel single nucleotide polymorphisms (SNPs) and 3 bases different from the reference sequence were detected in the region studied. Among these 2 novel SNPs and 1 different base were located in or near several bases of binding sites. The gene frequencies of the novel SNPs had no significant difference between CML and control people.CONCLUSION:
Sequence polymorphisms were found in the 5' promotor region of BCR gene, most of them being SNPs. No relativity can be validated between the SNPs and the disease. But it appears that some SNPs might have the probability of bringing influence to the transcription and expression of the gene.
