This gene was initially published as med-6 and in that paper the authors determined it was the same gene as let-425. However, the med gene class was already reserved for a different use and so it was agreed that mediator genes should be in the mdt gene class. Thus med-6 in WBPaper00004853 is the same gene as mdt-6 which is the same gene as let-425. The main name for this gene remains mdt-6. [krb 030513]
