In lung cancer, this association is largely driven by ASXL1-mutant clones. Specifically, high variant allele fraction (high-VAF) ASXL1 conferring a significantly increased risk (hazard ratio = 3.2), and the associations remained robust after adjustment for age, sex, body mass index (BMI), smoking status, and genetic ancestry. Notably, ASXL1 CHIP was substantially enriched among smokers, and its association with lung cancer risk was restricted to ever-smokers, highlighting a key interaction between CHIP and environmental exposure. The enrichment of ASXL1 CHIP in lung cancer was further validated in two independent cancer-only cohorts, including MSK-IMPACT and TCGA. In addition, rare germline variant association analysis revealed that germline variation in ASXL1 had the strongest association with lung cancer susceptibility among all solid tumors.  \nConclusions: Collectively, our findings support a model in which smoking–associated expansion of ASXL1-mutant clones contributes to lung cancer development and suggest that gene-spec","cbCaiqZWgFBZKqoD","https://ap.wps.com/l/cbCaiqZWgFBZKqoD","pdf",1498708,23,"English","# Abstract\n## Introduction\n## Methods\n## Results\n## Conclusions\n# Keywords\n# Abbreviations\n# Introduction","[{\"question\":\"What question does the study address about CHIP and cancer risk?\",\"answer\":\"The study evaluates how gene-specific CHIP relates to risk across 19 solid cancer types, noting that CHIP’s role in solid cancers is not fully resolved.\"},{\"question\":\"Which solid cancer showed the strongest CHIP association?\",\"answer\":\"Lung cancer exhibited the strongest association, driven largely by ASXL1-mutant clones.\"},{\"question\":\"How is the ASXL1 CHIP–lung cancer relationship influenced by smoking?\",\"answer\":\"ASXL1 CHIP was substantially enriched among smokers, and the association with lung cancer risk was restricted to ever-smokers, indicating an interaction between CHIP and environmental exposure.\"}]","Gene-Specific Analysis of Clonal Hematopoiesis Identifies ASXL1 as a Risk Factor for Lung Cancer | PDF",1790128422,58]
