This invention relates to methods and compositions for assessing an amount of non-native nucleic acids in a sample, such as from a pregnant subject with the non-native nucleic acids being fetal specific. The methods and compositions provided herein can be used to determine risk of a condition, such as a fetal condition, in a pregnant subject.

The present invention is based on a detection method of the 9 KRAS mutations Gly12Ser, Gly12Arg, Gly12Cys, Gly12Asp, Gly12Ala, Gly12Val, Gly13Asp, Gln61His and Gln61Leu, in a sample susceptible of containing one or more of such mutations, based on amplification of the sample with the primers of the present invention. Further, the present invention relates to (i) a kit which comprises, amongst its components, reagents for ARMS amplification including one or more of the primers of the present invention; (ii) the primers themselves; and (iii) use of the method, kit and primers of above, for the diagnosis/prognosis of a pathological condition in a patient, particularly, of cancer.
