A twist on admixture mapping

A new study uses genome-wide SNP genotypes to identify a subset of children undergoing therapy for acute lymphoblastic leukemia that are at increased risk for relapse. Borrowing from the classical approach of admixture mapping, the work shows how genome-wide assessment of genetic ancestry can be used as a biomarker for disease outcome.
