Age is the dominant risk factor for infectious diseases, but the mechanisms linking age to infectious disease risk are incompletely understood. Age–related mosaic chromosomal alterations (mCAs) detected from genotyping of blood–derived DNA, are structural somatic variants indicative of clonal hematopoiesis, and are associated with aberrant leukocyte cell counts, hematological malignancy, and mortality. Here, we show that mCAs predispose to diverse types of infections. We analyzed mCAs from 768,762 individuals without hematological cancer at the time of DNA acquisition across five biobanks. Expanded autosomal mCAs were associated with diverse incident infections (hazard ratio (HR) 1.25; 95% confidence interval (CI) = 1.15–1.36; P = 1.8 x 10-7), including sepsis (HR 2.68; 95% CI = 2.25–3.19; P = 3.1 x 10-28), pneumonia (HR 1.76; 95% CI = 1.53–2.03; P = 2.3 x 10-15), digestive system infections (HR 1.51; 95% CI = 1.32–1.73; P = 2.2 x 10-9) and genitourinary infections (HR 1.25; 95% CI = 1.11–1.41; P = 3.7 x 10-4). A genome–wide association study of expanded mCAs identified 63 loci, which were enriched at transcriptional regulatory sites for immune cells. These results suggest that mCAs are a marker of impaired immunity and confer increased predisposition to infections. |
