Somatic inflammatory gene mutations in human ulcerative colitis epithe
With ageing, normal human tissues experience an expansion of somatic clones that carry cancer mutations1–7. However, whether such clonal expansion exists in the non-neoplastic intestine remains unknown. Here, using whole-exome sequencing data from 76 clonal human colon organoids, we identify a unique pattern of somatic mutagenesis in the inflamed epithelium of patients with ulcerative colitis….
