Multi-center genetic study of hypertension: The Family Blood Pressure Program (FBPP)
Insights
The Family Blood Pressure Program (FBPP) unified four networks to study blood pressure genetics across diverse populations. This collaboration created a large, pooled dataset for comprehensive genetic analysis of hypertension.
Area of Science:
- Genetics
- Cardiovascular Health
- Population Health
Background:
- The Family Blood Pressure Program (FBPP) comprised four independent multicenter networks.
- These networks focused on the genetics of blood pressure and hypertension using diverse approaches.
- Participants were recruited from African American, Mexican American, Asian, and non-Hispanic white populations.
Purpose of the Study:
- To unify four distinct research networks into a cohesive program.
- To facilitate the genetic study of blood pressure and hypertension across diverse ethnic groups.
- To create a comprehensive, pooled dataset for genetic analysis.
Main Methods:
- Standardized clinic and laboratory protocols were implemented for core variables.
- Coordinated laboratory efforts minimized duplication.
- Genome-wide marker typing was performed by a single laboratory.
- A pooled dataset of phenotype and genotype information was created from over 11,000 individuals.
Main Results:
- Successful unification of four independent networks into the FBPP.
- Development of standardized protocols for cross-network data comparison.
- Creation of a large, integrated dataset for genetic research on blood pressure.
Conclusions:
- The unified FBPP enables robust genetic analysis of blood pressure and hypertension.
- The program's diverse population recruitment enhances the generalizability of findings.
- The pooled dataset provides a valuable resource for understanding the genetic basis of hypertension.
Abstract:
The Family Blood Pressure Program (FBPP) consists of 4 independently established multicenter networks of investigators who have complementary approaches to the genetics of blood pressure levels and hypertension. The program has recruited participants from the African American, Mexican American, Asian, and non-Hispanic white populations. Each network utilized study designs, laboratory measurements, and analytic methods that made efficient use of the unique characteristics of their populations and the investigators' expertise. The individual networks subsequently unified core study components into a single cohesive program. The unified FBPP includes (1) standardized clinic and laboratory protocols for core variables to facilitate direct comparison of results among networks, (2) coordination among laboratories to avoid unnecessary duplication of effort, (3) utilization of a single laboratory for genome-wide marker typing, and (4) a pooled data set containing phenotype and genotype information from >11 000 individuals.
