PedGenie: A Tool for Genetic Association Testing in Families
Author Information
Author(s): Kristina Allen-Brady, Jathine Wong, Nicola Camp
Primary Institution: University of Utah
Hypothesis
Can PedGenie effectively analyze genetic associations in extended pedigrees?
Conclusion
PedGenie is a valid and flexible tool for genetic association testing that can handle complex family structures.
Supporting Evidence
- PedGenie provides valid p-value calculations for genetic association tests.
- A significant association was found between the NBS1 tSNP rs709816 and breast cancer.
- The study included 462 breast cancer cases and 572 controls.
Takeaway
PedGenie helps scientists study how genes might be linked to diseases by looking at family trees, making it easier to find connections.
Methodology
PedGenie uses Monte Carlo significance testing to analyze genetic markers in pedigrees of any size, allowing for both qualitative and quantitative traits.
Potential Biases
There is a risk of bias due to the relatedness of individuals in the case-control cohort.
Limitations
The study may be limited by the complexity of family structures and the potential for related individuals in the case-control cohort.
Participant Demographics
Participants were selected from 139 high-risk Utah breast cancer families, primarily of Northern and Western European descent.
