Clinical Significance

Follicular lymphoma is the most common type of non-Hodgkin's lymphoma in the United States. Up to 90% of follicular lymphomas carry BCL-2/JH t(14;18) (q32;Q21) chromosome translocation. The presence of the BCL-2 translocation has been associated with poor prognosis in one group of diffuse large-cell and follicular lymphoma patients. Analysis of BCL-2 translocations provides an important marker for detection and monitoring of malignancy during patient treatment and follow up.
