“…Such a replication in an independent dataset would greatly strengthen the credibility of the variant we propose (Chanock et al, 2007). While all science progresses by the independent validation of experimental results, with GWA studies replication reduces the probability that the result is related to subtle population stratification (though our study is conducted in a homogeneous population, well suited for GWA studies) or to the issue of multiple comparisons (which we control for using the gold standard and, many argue, overly conservative Bonferroni correction).…”

“…For instance, winner's curse would be exacerbated by the smaller size of the replication sample. Chanock et al (2007) suggest, as far as possible, study design and phenotype should match to maximize the chance of replication.…”

“…There are likely many contributing risk alleles for all complex traits and complex diseases such that no single allele can explain all of the phenotypic variation 50. This becomes problematic during replication using different breeds and populations because the markers identified might merely reflect breed differences, or the markers might represent different alleles conferring different levels of risk across breeds or populations.…”

“…FcgRIIa-131H/R; FcgRIIIa-158 V/F NO 1) Some conflicting data; positive data mostly from small studies Bibeau et al, 2009;Musolino et al, 2008;Kim et al, 2006;Weng and Levy, 2003;Carlotti et al, 2007 false discovery is minimized either (optimally) by inclusion of a replication set, or by conservative adjustment for multiple comparisons (Chanock et al, 2007;van den Oord, 2008). Studies which are underpowered to adequately test less common variantsdvariants which in reality may be potentially important pharmacogenomic markersdcan have (falsely) negative results and can confuse the ability to understand conflicting data from several studies on a given drugegene pair.…”
