  1. Shown are the observed (obs) and expected (exp) numbers of replacement (R) and silent (S) mutations within each unique clonally related variant at each time point for members of the big clone in Sjögren’s syndrome subject 2. Both the complementarity-determining region (CDR) and the framework region (FWR) exhibit significant negative selection at all time points and overall (P <0.05 by the focused selection test; see Methods). N, number.
