*Controls used by Forkosh et al were non-AJ whites obtained from the gnomAD dataset (gnomAD V.2.1.1 non-cancer NFE) and thus not geographically matched with the cases (USA commercial laboratory). These would largely overlap with the gnomAD non-Finnish European controls included in the table and, therefore, have not been included as matched controls for this study.
