Despite the observation that many of the clonal mosaic anomalies observed here are characteristic of hematological cancer, the fraction of subjects with one or more mosaics who have a record of hematological cancer before DNA sampling is low. This fraction was estimated as 2.8% (95% CI=1.0 – 4.7%) in 291 mosaic subjects (with DNA from blood; from 13 GENEVA studies; using medical records, self-reported conditions and study exclusion criteria, as described in the Supplementary Note).
