Hypothesis
Can candidate genes be associated with rheumatoid arthritis using related cases?
Conclusion
The study found significant associations between several SNPs in the candidate gene PTPN22 and rheumatoid arthritis status.
Supporting Evidence
- Several SNPs in the candidate gene PTPN22 showed significant associations with RA status.
- SNP9 (R620W) had the strongest association with RA status.
- Other candidate genes like CTLA4, HAVCR1, and SUMO4 also showed significant associations.
Takeaway
Researchers looked at genes to see if they are linked to rheumatoid arthritis and found some that are.
Methodology
Case-control association analysis using weighted composite likelihood ratio test on SNP markers.
Potential Biases
Potential bias from the random selection of cases from families.
Limitations
The study may have limitations due to the exclusion of some SNPs and the random selection of cases.
Participant Demographics
Participants included 1256 cases from 665 nuclear families and 1519 unrelated controls.
