The glial cell neoplasms are not fully classified by using cellular morphology. However, this is possible using known molecular markers in glial development. Oligo-dendrocyte lineage gene induces differentiation of neural progenitors and putative immature progenitor cells of the adult central nervous system. These oligo-dendrocyte lineage genes OLIG1 and OLIG2 encode basic helix-loop-helix transcription factors. The murine bHLH transcription factors found in chromosome 21 are essential for oligo-dendrocyte development. Moreover, OLIG3 of the OLIG family is known to be linked with the brain and spinal cord development. Therefore, it is of interest to analyse oligodendrocyte lineage genes in the OLIG family of bHLH domain for the understanding of oligo-dendrogenesis in eukaryotes. We report several bHLH domain linked basic-helix-loop-helix transcription factors in Homo sapiens and Mus musculus from this analysis. Thus, genomics data analysis of OLIG family of bHLH transcription factors help explain observed similarity and differences within the molecular evolutionary context and hence assess the functional significance of the distinct genetic blueprints.
