NOVEL MARKERS FOR DETECTING MICROSATELLITE INSTABILITY IN CANCER AND DETERMINING SYNTHETIC LETHALITY WITH INHIBITION OF THE DNA BASE EXCISION REPAIR PATHWAY

摘要

The present application relates to the field of cancer, particularly to mismatch repair (MMR-)deficient tumors. New markers are presented herein that have a high sensitivity to detect whether a tumor is mismatch repair deficient or not. The markers are particularly mutations in microsatellite regions. Accordingly, methods are provided for diagnosing microsatellite instability of a tumor, comprising determining the presence of these markers. Further, kits are provided to detect the presence of these markers (or subsets thereof) in a sample.
