What is TOPMed?

Trans-Omics for Precision Medicine (TOPMed), is a program of the National Heart, Lung and Blood Institute (NHLBI), a part of the National Institutes of Health, which aims to improve scientific understanding of the fundamental biological processes that underlie heart, lung, blood, and sleep (HLBS) disorders and advance precision medicine in ways that lead to disease treatments tailored to individuals’ unique genes and environments.

TOPMed supports these scientific advances through the integration of whole-genome sequencing (WGS) and other omics data (e.g., metabolic profiles, epigenomics, protein and RNA expression patterns) with molecular, behavioral, imaging, environmental, and clinical data from pre-existing parent studies that have large samples of human subjects with rich phenotypic characterization and environmental exposure data. TOPMed also collects environmental and behavioral data, such as dietary habits, physical activity, and socioeconomic factors, to provide a more comprehensive understanding of the factors that contribute to these disorders.

TOPMed Artificial Intelligence Initiative (TOPMed-AI)

NHLBI’s TOPMed program aims to leverage the power of artificial intelligence (AI) and machine learning (ML) to accelerate the understanding of HLBS disorders. By utilizing the vast genomic data resources available through TOPMed and the computing infrastructure of BioData Catalyst (BDC), researchers will be able to develop advanced AI methods to analyze complex data and identify patterns that may lead to new insights and potential innovations for precision medicine.  The initiative will bring together AI/ML and other multidisciplinary experts to collaborate on innovative approaches to analyze and interpret TOPMed data.  The coordination center (AI-CC) at Westat serves as the central hub for coordinating research projects.

Initial use-cases for the TOPMed-AI initiative include:

  • Women’s health across the lifespan, starting with a focus on mid-life/menopause transition.
  • Imaging of lung disease. Radiogenomics focusing on chest CT data and including other imaging data as the program evolves.

Explore the Data

The TOPMed program provides data resources for researchers studying heart, lung, blood, and sleep disorders. These data resources include various types of genomic and other data, such as whole-genome sequencing, whole-exome sequencing, RNA sequencing, epigenetic data, metabolomic data, and proteomic data. Researchers who wish to access TOPMed data, including electronic health records, medical imaging data, and other patient health information, must get approval through the Database of Genotypes and Phenotypes (dbGaP). Once approval is granted, researchers can access the data from NHLBI BioData Catalyst® (BDC) or dbGaP.

BioData Catalyst (BDC)

  • Cloud-based computing ecosystem

  • Features secure workspaces, tools, applications, and workflows

  • Hosts data and supports collaboration

The TOPMed program uses BioData Catalyst (BDC) as a resource to facilitate research efforts. BDC is a cloud-based ecosystem where researchers can access NHLBI datasets, including TOPMed data, and leverage innovative data analysis tools, applications, and workflows to accelerate their research efforts. Additionally, BDC allows researchers to bring their own data, collaborate, and share their findings with other researchers in the community, ultimately driving discovery and scientific advancement in precision medicine.

Access BioData Catalyst

TOPMed Data Freeze 9

  • Variant discovery was initially made on approximately 206,000 samples.
  • 781 million single nucleotide variants were identified.
  • 62 million short insertion/deletion variants were identified and passed variant quality control (QC).

Note: These variant counts are slightly smaller than the corresponding numbers in data freeze 9 due to omitting sites that show no variation in TOPMed samples. More information about WGS methods can be found by selecting a freeze listed on the Methods page.

Omics Data Releases

TOPMed Omics data processing is being performed by several sequencing centers. The program requires that omics data be submitted to dbGaP with thorough documentation of bio-sampling, laboratory methods, and sample provenance. Visit the Methods webpage and scroll to the Standards, Pipelines and Flowcharts for Data Processing section to find available documented omics pipelines specific to omics type and phase. Below is a summary of the approved data sources for each study/cohort name categorized by data type.

Notes: 

“phs” is a dbGaP study accession number prefix indicating a phenotype study. A study accession number is a unique, stable, and versioned identifier.

AFGen dbGaP IDs: phs001435 , phs001543 , phs001624 , phs001732 , phs001600 , phs001189 , phs001546 , phs001606 , phs001547 , phs001725 , phs001545 , phs000993 , phs001598 , phs001062 , phs001434 , phs001544 , phs001024 , phs001601 , phs001933 , phs000997 , phs001032 , phs001040

ATGC dbGaP IDs: phs001728 , phs001729 , phs001730 , phs001602 , phs001603 , phs001604 , phs001605 , phs000920, phs001542 , phs001661 , phs001727 , phs000921 , phs001467

In the table, you may encounter phs links that redirect to a dbGaP error page. If so, this is because the TOPMed dbGaP study webpages are not available until the study accession is released.

TOPMed is generating a rich resource of multi-omics data that will include approximately 40,000 samples undergoing RNA-sequencing, 37,000 samples from metabolomics profiling, 57,000 samples from DNA methylation, and 4,000 samples from proteomics assaying. These projected totals include all stages of progress, from DNA/RNA that are currently being extracted to those that are undergoing sequencing/profiling or those that have completed the sequencing/profiling pipelines. Therefore, most omics data are in the process of being generated and will be released in the future.
