GID4 (17p11.2) / OLIG2 (21q22.11)OLIG2 (21q22.11) / TENM4 (11q14.1)


Note OLIG2 is an essential transcriptional regulator in motoneuron and oligodendrocyte development.


Description 329 amino acids; 32 kDa; contains 1 basic helix-loop-helix DNA-binding domain (bHLH).
Expression Olig2 is expressed in the ventral thalamus of developing mice.
Function Required for oligodendrocyte and motor neuron specification in the spinal cord.

Implicated in

Entity T-cell lymphoma
Cytogenetics Translocation t(14;21)(q11.2;q22)
Hybrid/Mutated Gene T-cell receptor promoter translocated upstream of OLIG2.
Abnormal Protein none
Entity Brain cancer
Disease Oligodendroglioma, astrocytoma, glioblastoma.
Prognosis variable
Cytogenetics No known genetic abnormalities in OLIG2.
Hybrid/Mutated Gene n/a
Oncogenesis OLIG expression in brain cancer raises possibilities that it could regulate behavior of tumor cell populations but this has not been demonstrated.
