Abstract

The PAX5 gene, which encodes the B-cell specific activator protein, is one of the most important factors in determination of B-cell development. This gene is the main target of somatic mutations in acute B lymphoblastic leukemia (B-ALL). For example, point mutations, deletions, as well as other gene rearrangements may lead to several forms of B-cell malignancy. In this study, we obtained 50 blood samples from patients diagnosed with ALL, and screened for PAX5 mutations using sequencing in exons 1, 2 and 3. We found a heterozygous germline variant, c.113G>A (p.Arg38His), which affects the paired domain of PAX5. It seems that this mutation is pathogenic, but is recessive. Our findings suggest that this mutation in a single allele of the PAX5 gene is not sufficient to cause disease, and it is possible that other alleles are also involved in the onset of B-ALL.

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
