Optimal unified approach for rare-variant association testing with application to small-sample case-control whole-exome sequencing studies.

Abstract excerpt

We propose in this paper a unified approach for testing the association between rare variants and phenotypes in sequencing association studies. This approach maximizes power by adaptively using the data to optimally combine the burden test and the nonburden sequence kernel association test (SKAT). Burden tests are more powerful when most variants in a region are causal and the effects are in the same direction,...
