Primary Outcome Measures:
  • Genetic Association with risk for rheumatoid arthritis [ Time Frame: 10 years ] [ Designated as safety issue: No ]
    The project aims to identify risk alleles for rheumatoid arthritis using association methods in trio families, combined with data from singleton cases and multiplex families

Biospecimen Retention:   Samples With DNA

DNA, plasma, serum and cells

Estimated Enrollment: 3000
Study Start Date: October 2002
Estimated Study Completion Date: December 2015
Estimated Primary Completion Date: December 2015 (Final data collection date for primary outcome measure)
Detailed Description:

The identification of genes for complex disorders such as RA requires large numbers of genetically informative families. This study enrolls people diagnosed with with RA and their families.

This study will enroll 1000 RA patients and their parents. Participants with RA will be evaluated at his or her doctor's office or other location convenient for the participant. Participants will have a brief phone interview with a study coordinator and a blood sample will be obtained. Disease evaluation will be done at one visit and will include confirmation of diagnosis, a 28 joint count, joint alignment and mobility score (JAMS) and administration of a health assessment questionnaire.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Persons with RA who have two living biological parents. Parents can be affected or unaffected with RA. We call the family units "trios".


Inclusion Criteria:

  • Adult onset RA
  • Diagnosis of RA made between 18 and 60 years old
  • Both parents alive and willing to participate
  • Parents may have diagnosis of RA (affected) or be unaffected

Exclusion Criteria:

  • Inflammatory bowel disease
  • Lupus
  • Psoriatic arthritis
