| Clinics and Pathology |
| Disease | t(6;14)(p21.1;q32.3) is mainly multiple myeloma / plasma cell leukaemia, but also observed in diffuse large B cell non Hodgkin lymphoma (DLBCL) and marginal zone B cell lymphoma. |
| Phenotype / cell stem origin | mature B-lymphocyte |
| Epidemiology | Approximately 4% of primary MM cases. MGUS? Should be rather frequent in lymphoma but not yet systematically estimated. |
| Cytology | CD138+ dystrophic or not dystrophic plasma cells in MM; CD5+ diffuse large B cell lymphoma and splenic lymphoma with villous lymphocytes in NHL. |
| Prognosis | No prognosis value clearly established. |
| Cytogenetics |
| Cytogenetics Morphological | May be not easy to detect. |
| Cytogenetics Molecular | Translocation detected by FISH with CCND3 and IgH probes; der(14) sometimes in multiple copies; der(6) sometimes lost. |
| Additional anomalies | Complex karyotype in most cases. |
| Genes involved and Proteins |
| Gene Name | CCND3 |
| Location | 6p21.1 |
| Note | synonym CGD3 |
| Dna / Rna | 6,88kb, 5 exons, 5¹ - 3¹ telomeric orientation. |
| Protein | 32,5kDA, 292 amino acids; regulates Rb1 phosphorylation and, hence, cell cycle G1/S transition, as a result of interaction with CDK4 and CDK6 protein kinases. |
| Gene Name | IGH |
| Location | 14q32.3 |
| Result of the chromosomal anomaly |
| Description | 6p21.1 breakpoint centromeric to CCND3; 14q32.3 breakpoint in the switch region; leads to proximity between IGHS sequences and CCND3 on der(14). |
| Note | no |
| Oncogenesis | Dysregulation and overexpression of CCND3. |
| To be noted |
| Case Report | A case of Chronic Lymphocytic Leukemia (CLL) with a rare chromosome abnormality: t(1;14;6)(q21;q32;p21), a variant of t(6;14)(p21;q32). |

| Cyclin D3 immunoreactivity in follicular lymphoma is independent of the t(6;14)(p21.1;q32.3) translocation or cyclin D3 gene amplification and is correlated with histologic grade and Ki-67 labeling index. |
