Dumitru Brinza, Jingwu He, Alexander Zelikovsky
2006 2006 International Conference of the IEEE Engineering in Medicine and Biology Society  
In the reduced set of SNPs, we then propose to apply a novel combinatorial method for finding disease-associated multi-SNP combinations (MSCs).  ...  Unfortunately, an exhaustive search among all possible corresponding multi-markers can be unfeasible even for small number of SNPs let alone the complete genome.  ...  Since statistically significant MSCs are searched among many such combinations, the computed pvalue requires adjustment for multiple testing.  ...
