Somatic point mutations in the translocated bcl-2 genes of non-Hodgkin's lymphomas and lymphocytic leukemias: implications for mechanisms of tumor progression.

Abstract excerpt

The t[14;18] chromosomal translocation is the most common cytogenetic abnormality found in hematolymphoid malignancies. The t[14;18] fuses the bcl-2 gene at 18q21 with the immunoglobulin heavy-chain locus at 14q32, resulting in deregulated expression of bcl-2 and production of high levels of its encoded 26-kD protein in the majority of non-Hodgkin lymphomas. Recent data indicate that somatic point mutations...
