Genes and Blood Pressure Tracking
Author Information
Author(s): Wang Tao, Zhu Guohua, Keen Kevin J
Primary Institution: Case Western Reserve University
Hypothesis
Genes might be responsible for the tracking phenomenon of systolic blood pressure (SBP).
Conclusion
One or more genes in the range of 200–240 cM on chromosome 1 may be related to the tracking phenomenon of SBP.
Supporting Evidence
- The heritability of SBP was found to be statistically significant.
- Linkage analysis indicated regions on chromosomes 1, 3, 10, and 13 related to SBP tracking.
- Imputation analysis was shown to be more efficient than complete case analysis in some instances.
Takeaway
This study looked at how some genes might affect blood pressure over time, showing that certain genes could help explain why some people have higher blood pressure as they age.
Methodology
A mixed model was used to analyze SBP measurements from family members, with both complete and imputed data considered.
Potential Biases
There is a risk of losing information due to treating some SBP values as missing after treatment started.
Limitations
The study faced challenges with missing data and the treatment of subjects, which could introduce bias.
Participant Demographics
Participants were from the Framingham Heart Study, including original and offspring cohorts.
