[EX Q]: Question: Is development of rheumatoid arthritis associated with two polymorphisms in the Crohn 's disease gene CARD15?
Answer: Within defined statistical parameters, we excluded a role for the CARD15 1007fs and R702W variants in RA susceptibility. These data do not preclude a role for other polymorphisms in the CARD15 gene in RA susceptibility. Results from other autoimmune and inflammatory diseases will reveal whether the CARD15 gene is in fact a common autoimmune susceptibility locus.

no
