Comparison of two linkage inference procedures for genes related to the P300 component of the event related potential.

abstract：:We propose a new approach to detect gene × gene joint action in genome-wide association studies (GWASs) for case-control designs. This approach offers an exhaustive search for all two-way joint action (including, as a special case, single gene action) that is computationally feasible at the genome-wide level and has r...
