Scientists have decoded the complete DNA of a cancer patient and traced her disease to its genetic roots.
The Washington University team identified 10 gene mutations which appeared key to the development of the woman's acute myeloid leukaemia.
Just two of these had been linked to the disease before.
The sequencing technique, described in the journal
Nature, could be applied to other cancers and aid the design of targeted drugs.
