Comparison of Haplotype Methods for Rheumatoid Arthritis Data
Author Information
Author(s): Li Xin, Li Jing
Primary Institution: Case Western Reserve University
Hypothesis
Can haplotyping methods using families provide better accuracy than those using unrelated individuals on simulated rheumatoid arthritis data?
Conclusion
PedPhase outperforms fastPHASE in phasing accuracy, while fastPHASE is better for genotype inference.
Supporting Evidence
- PedPhase has better phasing accuracy than fastPHASE.
- fastPHASE performs better for missing genotype imputation.
- Family constraints improve haplotyping accuracy.
Takeaway
This study looked at two ways to figure out genetic information from families and unrelated people. One way was better at getting the right answers when looking at families, while the other was better at guessing missing information.
Methodology
The study compared two haplotyping programs, PedPhase and fastPHASE, using simulated rheumatoid arthritis data from 1500 families.
Limitations
The study only used simulated data and focused on a specific family size, which may not represent all scenarios.
Participant Demographics
1500 nominally unrelated nuclear families of size 4.
