Higher West African (YRI) ancestry proportion in MAGENTA cohort participants is linked to more allele-specific expression–positive genes per person, even after key covariate adjustments.
- Why it matters: Most allele-specific expression work has focused on European-descent samples, leaving uncertainty about how ancestry within admixed individuals shapes regulatory differences in blood.
- What they did: The study combined phased whole-blood RNA-seq with local ancestry inference in 779 MAGENTA participants, testing ancestry associations with ASE-positive gene counts and performing gene-level and genome-wide window scans.
- The result: Gene-level testing found 2,053 of 15,008 genes with significant imbalance across population groups, and a genome-wide scan identified 52 replicated ancestry-associated loci, with locus-specific dominance at 11 loci.
