Clinics and Pathology

Disease

Phenotype stem cell 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 (cyclin D3)
Location
6p21.1
Note
synonym CGD3
Dna rna description
6,88kb, 5 exons, 5¹ - 3¹ telomeric orientation.
Protein description
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 (Immunoglobulin Heavy)
Location
14q32.33

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.
