KRAS assays from FFPE

Wednesday 7 December 2011

Activating mutations of the BRAF and KRAS genes cause constitutive stimulation of an important cell-signaling pathway promoting tumorigenesis, and are increasingly recognized as determinants of response to targeted cancer therapies.

The frequency of KRAS mutations is about 32%, with G>A transitions at position 2 of codons 12 and 13 being most prevalent.
