Abstract:
This study was aimed to explore the single nucleotide polymorphism (SNPs) of breakpoint cluster region of bcr gene in Chinese people and the relationship between SNPs and chronic myelogenous leukemia (CML). A 3.12 kb region spanning from exon 13 to exon 15 in the bcr region were screened by DNA pooling and denaturing high performance liquid chromatography (dHPLC), and the results were verified by sequencing. The results indicated that 6 novel SNP sites and 2 bases different from reference sequence were confirmed in the region studied, and the frequency of 6 novel SNP sites in studied population was obtained, one SNP of which was found in exon 13 and caused a nonsynonymous mutation. The gene frequencies of novel SNPs had no significant difference between CML and control people. It is concluded that sequence polymorphisms in the major breakpoint cluster region of bcr gene are found, most of which are SNPs, No relationship can be confirmed between SNPs and CML disease.

Diversity of Antigen Receptors
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...

Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
