TIMELINE-Key dates in Genzyme's manufacturing crisis

Aug 13 (Reuters) - U.S. biotechnology company Genzyme Corp GENZ.O, a maker of extremely expensive lifesaving medicines for rare genetic disorders, is considering an acquisition offer by French drugmaker Sanofi-Aventis SASY.PA.

A key focus of any talks will be Genzyme’s ability to move past a viral contamination at its main plant that caused severe shortages of its most important products. [ID:nN12260234]
