Sorting wheat from chaff in genomewide association studies may well entail more time and effort than the original study. It is therefore important to critically evaluate results from truly independent data sets and, as this study attempts, to take the analysis beyond just statistical association toward some sort of functional analysis. That said, this would appear to be a fairly dramatic example of winner's curse, for the strength of association reported in the Irish sample would not have warranted even the briefest mention in the original Cardiff study (O'Donovan et al., 2008).
