Abstract:
|
Understanding the genome-wide association of the occurrence of serious adverse drug reactions (SADRs) for a drug is a significant challenge in drug development and drug therapy. Collection of blood samples for such testing "post facto" is inefficient and costly. Consequently, limiting collection of "post facto" samples only from subjects with SADRs in conjunction with publicly available SNP control data sets requires careful power assessment. Power under conventional univariate methods(Menashe et al 2008) for different levels of multiple factors was assessed, assuming the prevalence of a SADR of 0.01, 1 million SNPs, recessive allele frequency of 0.1 or 0.2 for both gene and marker, and a ratio of 3 to 30 on relative risk (RR) for associated homozygous alleles SNP genotypes. Power from a computer simulated sequential genome-wide multivariate analysis (Kelly et al 2006) is also presented.
