CHARACTERIZING THE QUANTITATIVE GENETIC CONTRIBUTION TO RHEUMATOID ARTHRITIS USING DATA FROM TWINS Conclusion. Genetic factors have a substantial contribution to RA in the population, accounting for 60% of the variation in liability to disease. Although tempered by power considerations, there is no evidence in these twin data that the overall genetic contribution to RA differs by sex, age, age at disease onset, and disease severity.

Rheumatoid arthritis • We expect more subdivisions to be developed soon when additional biomarkers as well as additional clinically relevant features are identified that associate with different genetic polymorphisms and environmental triggers.
