Identity

ICD-Topo C420,C421,C424 BLOOD, BONE MARROW, & HEMATOPOIETIC SYS
Atlas_Id 2140

Clinics and Pathology

Disease Diffuse large B-cell lymphoma (DLBCL)
Epidemiology One case to date, a female patient aged 80 years (Bertrand et al., 2007).
Prognosis The patient died 6 months after diagnosis.

Cytogenetics

Cytogenetics Morphological A complex karyotype was found, with an i(6)(p10), a +20, and other abnormalities.

Genes involved and Proteins

Note Breakpoints occurred close to MYC in 8q24 and 100 kb from COBL and 1Mb from IKZF1 in 7p12.
- COBL is an actin nucleator which uses its WH2 domains for binding actin, to promote actin filament formation. Role in neuromorphogenesis (dendrite formation and dendritic arborisation) (Schwintzer et al., 2011).
- IKZF1 is a zinc finger transcription factor involved in both activation and repression of target genes. IKZF1 is expressed during early embryonic hematopoiesis, including hematopoietic stem cells, lymphoid precursors, erythroid precursors, and myeloid precursors. It is also expressed in developing striatal neurons. In the adult, IKZF1 expression is mainly restricted to lymphopoietic tissues and peripheral blood leukocytes (review in John and Ward, 2011).
Gene Name MYC
Location 8q24.2
Protein DNA binding protein. Binds DNA as a heterodimer with MAX. Involved in various cellular processes including cell growth, proliferation, cell adhesion, apoptosis, angiogenesis, and stem cell behaviour modulation.
