It is likely that further susceptibility genes will be identified through follow-up of other signals for which the evidence from our scan is less conclusive (see below for some specific examples). For example, there are 58 further signals with single-point P values between 10-5 and 5×10-7 for which inspection of cluster plots verifies CHIAMO calls (Table 4). As described below, analyses which make use of selected case samples to expand the reference group should also provide a useful route to the prioritization of such putative signals for further analysis. For convenience, the strongest association results are presented separately for each disease in Supplementary Table 7.
