I definitely got ahead of myself, you are correct there is nothing to suggest that this study was done using subject data drawn in its majority or even a substantial fraction feom Japanese populations. I noted the affiliation with the Biobank Japan project and hastily assumed that this was the primary source of data for the study. Given that this would only be interesting in the context of the unusually homogeneous in a Japanese sample, and the consequent difficulty in compensating for this with data thus sourced, my original comment is no longer meaningful. Unfortunately its no longer possible to delete it.
