Extended Data Fig. 1

For each filter, the number of samples retained after applying the filter is shown. First, samples of broad European ancestry were retained, then samples were excluded in case of low call rate (<0.9), outlying heterozygosity rate (F < − 0.1 or F > 0.1), genetically predicted sex that did not match reported sex, a deviant number of SNVs, INDELs, singletons or outlying Ti/Tv or SNV/INDEL ratio, ≤2nd degree relatedness (one of each pair is kept) or outlying values on the first five principal components.
