- Study Description
This study is part of the NHLBI Trans-Omics for Precision Medicine (TOPMed) Whole Genome Sequencing Program. TOPMed is part of a broader Precision Medicine Initiative, which aims to provide disease treatments that are tailored to an individual's unique genes and environment. TOPMed will contribute to this initiative through the integration of whole-genome sequencing (WGS) and other -omics (e.g., metabolic profiles, protein and RNA expression patterns) data with molecular, behavioral, imaging, environmental, and clinical data. In doing so, this program aims to uncover factors that increase or decrease the risk of disease, to identify subtypes of disease, and to develop more targeted and personalized treatments. Two genotype call sets derived from WGS are now available, Freeze 8 (GRCh38) and Freeze 9b (GRCh38), with largely overlapping sample sets. Information about how to identify other TOPMed WGS accessions for cross-study analysis, as well as descriptions of TOPMed methods of data acquisition, data processing and quality control, are provided in the accompanying documents, "TOPMed Whole Genome Sequencing Project - Freeze 8, Phases 1-4" and "TOPMed Whole Genome Sequencing Project - Freeze 9b, Phases 1-4". Please check the study list at the top of each of these methods documents to determine whether it applies to this study accession.
The GenSalt study aims to identify genes which interact with dietary sodium and potassium intake to influence blood pressure in Han Chinese participants from rural north China. Whole genome sequencing will be conducted among 1,860 participants of the Genetic Epidemiology Network of Salt Sensitivity (GenSalt) Study. We will work in collaboration with participating TOPMed studies to identify novel common, low-frequency and rare variants associated with an array of cardiometabolic phenotypes. In addition, we will explore the relation of low-frequency and rare variants with salt-sensitivity among GenSalt study participants.
