  Recipients of allogeneic bone marrow transplants (BMT) or stem cell transplants (SCT) require clinical monitoring to allow for early diagnosis of such post-transplant adverse effects as rejection, graft vs. host disease (GVHD), or a malignancy relapse. Triaging of the transplant recipients in clinical settings is achieved by monitoring the Minimal Residual Disease (MRD) and measuring the amount of mixed chimerism in peripheral blood lymphocytes (PBL). While MRD monitoring involves detection of the malignancy-specific markers, measuring the extent of mixed chimerism can be achieved via general PCR-based methods. We have developed a SNP genotyping method to detect low levels of mixed chimerism in PBL and genomic DNA. Sensitivity is achieved by measuring a cumulative skew in genotyping data across a cohort of 92 independent SNP markers. This method showed a s.. View More»
