| Identity |
| Note | t(11;14) is mainly found in mantle cell lymphoma, but also in B-prolymphocytic leukaemia, in plasma cell leukaemia, in splenic lymphoma with villous lymphocytes, in chronic lymphocytic leukaemia, and in multiple myeloma, herein briefly described; all these diseases involve a B-lineage lymphocyte. |

| Clinics and Pathology |
| Disease | mantle cell lymphoma |
| Phenotype / cell stem origin | B-cell non Hodgkin lymphoma of the low to intermediate grade |
| Epidemiology | annual incidence 5/106; median age: 65 yrs |
| Clinics | advanced disease |
| Prognosis | median survival: 3 to 4 yrs |
| Disease | B-prolymphocytic leukaemia |
| Phenotype / cell stem origin | chronic lymphoproliferative disorder affecting mature B-cells |
| Epidemiology | rare disease; median age 70 yrs |
| Clinics | patients often present with advanced stage disease |
| Prognosis | median survival: 3 yrs |
| Disease | plasma cell leukaemia |
| Phenotype / cell stem origin | proliferation involving plasma cells |
| Epidemiology | rare disorder |
| Prognosis | median survival is less than a yr |
| Disease | splenic lymphoma with villous lymphocytes |
| Phenotype / cell stem origin | chronic B-cell lymphoproliferation |
| Epidemiology | rare disorder; median age: 70 yrs |
| Clinics | relatively benign clinical course |
| Prognosis | 80% 5-yr survival |
| Disease | chronic lymphocytic leukaemia |
| Phenotype / cell stem origin | chronic B-cell lymphoproliferation |
| Epidemiology | annual incidence 30/106; median age: 60-80 yrs |
| Clinics | often a slow evolutive disease |
| Prognosis | highly variable according to the staging: from staging A: survival not reduced compared to age matched population, to staging C: median survival of 2 yrs |
| Disease | multiple myeloma |
| Phenotype / cell stem origin | malignant plasma cell proliferation (terminally differenciated B-cell) |
| Epidemiology | annual incidence: 30/106; median age: 60 yrs |
| Prognosis | median survival: 3 yrs. |
| Cytogenetics |
| Cytogenetics Morphological | t(11;14) has earlier been thought to be the hallmark of the mantle cell lymphoma; actually, the frequency of t(11;14) is: 50-70% in mantle cell lymphoma, 10-20% in B-prolymphocytic leukaemia, in plasma cell leukaemia, and in splenic lymphoma with villous lymphocytes, and 2-5% in chronic lymphocytic leukaemia, and in multiple myeloma. |
| Cytogenetics Molecular | in particular interphase cytogenetics, are relevant in these diseases with an usually low mitotic index |
| Additional anomalies | sole anomaly in only 10% of cases; part of a complex karyotype in 2/3 of cases; numerous recurrent anomalies found conjointly (which is the primary?), particularly: +3, +7, del(9p), +18, + mar, found in about 10% of cases each; other: del(1p), del(6q), del(7q), -8, +12, del(13q), del(17p) |
| Variants | three way complex t(11;14; Var) exist and showed that the crucial event lies on der(14) |
| Genes involved and Proteins |
| Gene Name | BCL1 |
| Location | 11q13 |
| Dna / Rna | 5 exons |
| Protein | encodes the cyclin D1; role in the cell cycle control: G1 progression and G1/S transition |
| Gene Name | IgH |
| Location | 14q32 |
| Result of the chromosomal anomaly |
| Description | 5' BCL1 translocated on chromosome 14 near JH (junctions genes of IgH) and C in 3'; the breakpoint in BCL1 is in MTC (major translocation cluster), centromeric to the gene (in 5'), in 80% of cases, or dispersed in mTC1, 2, or 3 in 5'of the gene or in the 3' untranslated region of exon 5. |
| Description | no fusion protein, but promoter exchange; the immunoglobulin gene enhancer stimulates the expression of BCL1 |
| Oncogenesis | overexpression of BCL1 accelerates passage through the G1 phase. |
