A method for detecting a methylated genomic locus is provided. In certain embodiments, the method comprises: a) treating a nucleic acid sample that contains both unmethylated and methylated copies of a genomic locus with an agent that modifies cytosine to uracil to produce a treated nucleic acid; b) amplifying a product from the treated nucleic acid using a first primer and a second primer, wherein the first primer hybridizes to a site in the locus that contain methylcytosines and the amplifying preferentially amplifies the methylated copies of the genomic locus, to produce an amplified sample; and c) detecting the presence of amplified methylated copies of the genomic locus in the amplified sample using a flap assay that employs an invasive oligonucleotide having a 3′ terminal G or C nucleotide that corresponds to a site of methylation in the genomic locus.

The present invention relates to the field of pharmacogenomics and in particular to detecting the presence or absence of hypermethylated DNA. The detection of CpG methylation in marker DNA is useful for the diagnosis of cancers and the invention provides improved methods for this purpose. These improved methods allow in particular for a more sensitive detection of methylated marker DNA with high backgrounds of unmethylated marker DNA.
