for example, the estimated OR was >1.05 for only 10 loci, and 920 loci had an estimated OR of >1.02. When taking into account effects from the previously known loci, these analyses suggest that ~28% of familial risk is explained by common variants selected for iCOGS, of which ~14% can be explained by the 67 established loci (with a further ~20% due to higher penetrance loci).
