Abstract:
PAX5 rearrangements resulting in the expression of fusion transcripts account for 2-3% of childhood B-cell precursor acute lymphoblastic leukemia. Most PAX5 fusions are rare and many of them have only been described in a couple of, or even only in single, cases. We have identified the third case with a PAX5-AUTS2 fusion, which results from unbalanced t(7;9)(q11.2;p13.2) rearrangements. Our findings substantiate that PAX5-AUTS2 is a recurrent fusion gene in pediatric B-cell precursor acute lymphoblastic leukemia, and we summarize the clinical characteristics of such patients.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Cancer-Critical Genes I: Proto-oncogenes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
