Patent ID: 8709719

Claim:
A method for determining the prognosis of a breast cancer in a patient comprising the following steps: assaying a tumor sample from the patient for at least one prognostic marker of breast cancer and assessing the level of expression of the ZNF217 gene in said sample; and if the sample displays at least one prognostic marker classifying the breast cancer as having a favorable prognosis, re-classifying the breast cancer as having a poor prognosis if the ZNF217 gene is over-expressed in said sample, wherein the level of expression of the ZNF217 gene in the sample is assessed by quantification of the ZNF217 gene transcript(s) by reverse transcription and amplification, wherein the amplification is performed using a combination of primers comprising a first primer as forward primer and a second primer as reverse primer, the first primer comprising the sequence as depicted in SEQ ID NO 1 or the reverse primer comprising the sequence as depicted in SEQ ID NO 2, followed by quantitative detection of the amplicon obtained.
