GBAT: a gene-based association method for robust trans-gene regulation detection

Identification of trans -eQTLs has been limited by a heavy multiple testing burden, read-mapping biases, and hidden confounders. To address these issues, we developed GBAT, a powerful gene-based method that allows robust detection of trans gene regulation. Using simulated and real data, we show that GBAT drastically increases detection of trans -gene regulation over standard trans -eQTL analyses.
