RHEUMATOID FACTOR ACTIVITY ENCODED BY VARIANT IMMUNOGLOBULIN VARIABLE REGION

摘要

Diagnosis and therapy of inflammatory diseases is provided by detecting the presence of mutations in the framework regions of light chains of immunoglobulins. Particularly, a multiplicity of mutations in the framework region (3) at conserved sites is found to be associated with erosive arthritis. By detecting the presence of mutations in the nucleic acid or resulting encoded light chain, propensity for inflammatory diseases and prophylactic and therapeutic treatments is provided.
