A novel two-stage approach for epistasis detection in genome-wide case-control studies.

Abstract excerpt

A significant challenge in epistasis detection is the huge amount of data, which leads to combinatorial explosion. This study focuses on a two-stage approach for detecting epistasis only among single nucleotide polymorphisms (SNPs) that show some marginal effect. We present this two-stage approach based on the fusion of two criteria (TwoFC) to detect epistatic interactions. We fuse the G (2) test and absolute...
