Differences in mutational patterns between rheumatoid factors in health and disease are related to variable heavy chain family and germ-line gene usage.

Abstract excerpt

The sequences of the heavy chain variable (V(H)) segment and dissociation constants (Kd) of 14 IgM rheumatoid factors (RF) derived from 11 different germline gene segments from five healthy immunized donors (HID) are described. We extend a previous analysis of two clones from one donor using only the germline segment DP-10. In the present study, the mutation patterns of these new RF and the two earlier reported...
