EMK 1.0

:: DESCRIPTION

EMK (extended Monks and Kaplan method )is a program that can perform both allele- and genotype- based association tests in any pedigree structure. To evaluate the performance of EMK, we utilized simulated pedigree data and real data from our previous report of GSTO1 and GSTO2 genes in Alzheimer disease (AD). Both allele- and genotype-based EMK methods (allele-EMK and geno-EMK) showed correct type I error for various pedigree structures and admixture populations. The geno-EMK method showed comparable power to the allele-EMK test. By treating age-at-onset (AAO) as a quantitative trait, the EMK program was able to detect significant associations for rs4925 in GSTO1 (P= 0.006 for allele-EMK and P= 0.009 for geno-EMK), and rs2297235 in GSTO2 (P= 0.005 for allele-EMK and P= 0.009 for geno-EMK), which are consistent with our previous findings.
