Randomized trial identifies independent association signals in multi-ancestry populations, highlighting improved accuracy.

The aim is to enhance the identification of independent genetic associations using multi-ancestry GWAS data.
Developed Manc-COJO, a C++ software package to analyze GWAS summary statistics.
Jointly modeled association signals across different ancestry groups while considering ancestry-specific linkage disequilibrium.
Included simulation and real-data analysis scripts along with example datasets.
Manc-COJO improved detection of independent associations compared to single-ancestry COJO.
Significantly reduced false positives in multi-ancestry analyses.
Provided validated software tools to facilitate further genetic research.

Wang et al. (2026) studied this question.
