3 Figure 1 Characteristics of Clonal Hematopoiesis (CH) Mutations Identified in the Cohort (A) Number of mutations harbored per patient. (B) Density of mutations by VAF in blood and tumor tissue. (C) Patterns of mutation co-occurrence and number of patients with mutations in ten most recurrently mutated genes. The first 1,912 patients in the cohort underwent sequencing with a 341-gene assay, which did not include PPM1D but did include all other genes listed. The remaining patients (n = 6,898) underwent sequencing with a 410-gene assay, which included all genes shown. (D) Distribution of DNMT3A mutations within the cohort. Gene models are based on the UniProt database. (E) Distribution of PPM1D mutations within the cohort. Gene models are based on the UniProt database. (F) Association between CH and age/age distribution of patients in the cohort. Cell Stem Cell  , e4DOI: ( /j.stem ) Copyright © 2017 Elsevier Inc. Terms and Conditions

4 Figure 2 Distribution of Patients with CH across Solid Tumor Types and Signatures of CH Mutations (A) Detailed tumor types, and percentage of patients with CH and corresponding age distributions. This includes the 16 most frequently sequenced tumors, and patients with less common tumors are not included in this figure. Note that for detailed tumor types depicted, non-small cell lung cancer does not include small cell lung cancers or mesotheliomas. (B) Effect of smoking on observed CH mutations. Rates of different substitution types that lead to silent and non-silent CH mutations are compared among four groups: treatment-naive never smokers, treatment-naive smokers, previously treated (chemotherapy, RT, or both) never smokers, and previously treated (chemotherapy, RT, or both) smokers. (C) Rates of different substitutions with their nucleotide context are compared among the same four groups of patients. Cell Stem Cell  , e4DOI: ( /j.stem ) Copyright © 2017 Elsevier Inc.

5 Figure 3 Association between CH and Clonal Hematopoiesis with Presumptive Drivers (CH-PD) and Subsequent Hematologic Cancers and OS (A) Incidence of new hematologic cancer in patients with and without CH. (B) Incidence of new hematologic cancer in patients with and without CH-PD. (C) OS in CH versus non-CH (all ages). Time-point estimates for CH versus non-CH are 12-month OS: 0.70 (0.68–0.73) versus 0.74 ( ); 18-month OS: 0.57 (0.54–0.60) versus 0.64 (0.62–0.66); and 24-month OS: 0.50 (0.46–0.53) versus 0.55 (0.53–0.57). (D) OS in CH-PD versus non-CH-PD (all ages). Time-point estimates for CH-PD versus non-CH-PD are 12-month OS: 0.67 (0.62–0.74) versus 0.74 (0.72–0.75); 18-month OS: 0.55 (0.49–0.63) versus 0.63 (0.61–0.64); and 24-month OS: 0.48 (0.40–0.57) versus 0.54 (0.52–0.56). Differences in the incidence of new hematologic cancer were compared using Gray’s test, while survival differences were assessed using the Peto and Peto modification of the Gehan-Wilcoxon test. Survival was compared both overall and stratified based on categories of age, gender, and smoking status. Cell Stem Cell  , e4DOI: ( /j.stem ) Copyright © 2017 Elsevier Inc. Terms and Conditions
