Associated Diseases (KEGG IDs)A chromosomal aberration involving BCL2 has been found in chronic lymphatic leukemia. Translocation t(14;18)(q32;q21) with immunoglobulin gene regions. BCL2 mutations found in non-Hodgkin lymphomas carrying the chromosomal translocation could be attributed to the Ig somatic hypermutation mechanism resulting in nucleotide transitions. {ECO:0000269|PubMed:2875799, ECO:0000269|PubMed:3285301}.
General Description of Bcl-2 Oncoprotein .
Bcl-2 antibody is useful in differentiation of follicular lymphoma from reactive follicular proliferation (bcl-2 negative). In addition, bcl-2 expression has been shown to be correlated with disease prognosis in breast cancer, prostate cancer, ovarian cancer, endometrial cancer and colon cancer. The sensitivity of this antibody in diagnosis of follicular lymphoma is higher than other Bcl-2 antibody as reported by Masir et al. (3).

Bcl-2 Oncoprotein Information for Pathologists


BCL2 is a proto-oncogene at locus 18q21.3 the plays a role in inhibiting apoptosis. The BCL2 protein has a M.W. of 25 kDa.

Common Uses By Pathologists:

BCL2 staining is used to distinguish follicular hyperplasia of lymph node (germinal centers are BCL2 negative) from follicular lymphoma (germinal centers are BCL2 positive). However, there are reported cases of follicular lymphomas that are BCL2 negative (Am J Surg Pathol 2011;35:1691, Am J Surg Pathol 2009;33:591). BCL2 staining can also identify immature enteric ganglion cells in pediatric intestinal pseudo-obstruction (Am J Surg Pathol 2005;29:1017). BCL2 antibodies label diffuse large cell lymphoma which is an adverse prognostic factor in some studies (Mod Pathol 2005;18:1113, Clin Cancer Res 2011;15:7785). Myelodysplastic syndrome patients should be screened for BCL2 as increased expression is associated with progression. Finally, BCL2 may have prognostic value in early stage breast cancer (Br J Cancer 2010;103:668).
