Hypothesis
Can we identify causal SNPs associated with disease traits in the chromosome 6 region using linkage and association analysis?
Conclusion
The study identified two SNPs that explain most of the observed disease association in the chromosome 6 region.
Supporting Evidence
- The most significant region of linkage was found on chromosome 6.
- Highly significant TDT results were obtained in each replicate on chromosome 6.
- Stepwise regression identified SNPs that account for the association at the DR/C location.
Takeaway
Researchers looked at a part of chromosome 6 to find out which tiny changes in our genes might be linked to diseases, and they found a couple of important ones.
Methodology
Linkage and family-based association analysis using the Kong and Cox allele-sharing test and transmission/disequilibrium test.
Limitations
The study's findings may not generalize to other populations with different linkage disequilibrium patterns.
Participant Demographics
Affected-sib-pair families with parents and two children.
