Rare cases of MLS show a variant t(12;22) translocation, resulting in EWS-CHOP fusion gene.     ///    The remaining 1 case showed an EWS-CHOP fusion transcript.     ///    "To examine whether the molecular variability of TLS-CHOP or EWS-CHOP fusion transcript structure is associated with the degree of inhibition of adipogenesis, a comparative ultrastructural and RT-PCR-based analysis of 14 MLS was performed.
