Although these mutations occur in all proliferating cells, their accumulation under non-malignant conditions, such as in autoimmune disorders, has not been investigated. Here, we show that patients with newly diagnosed rheumatoid arthritis have expanded CD8(+) T-cell clones; in 20% (5/25) of patients CD8(+) T cells, but not CD4(+) T cells, harbour somatic mutations. In healthy controls (n = 20), only one mutation is identified in the CD8(+) T-cell p...
