HeartBioPortal 3.0 (HBP 3.0) consolidates cardiovascular genomic intelligence into a single browser-based environment, incorporating 594.3 million allele-frequency observations across 18.1 million rsIDs, 3.04 million structural-variant records, 66,900 protein isoforms, 17,128 gene-drug records, and a clinical guideline knowledge graph containing 42,895 entities and 106,304 relationships. Data sourced from the Million Veteran Program and public aggregate repositories are unified through a reproducible ingestion layer called DataHub, which standardizes provenance tracking across heterogeneous omics, variant, and phenotypic datasets.
The cardiovascular genomics field has long suffered from a fragmentation problem: actionable signals emerging from GWAS, rare-variant studies, and clinical sequencing are scattered across ClinVar, gnomAD, GTEx, PharmGKB, and dozens of disease-specific registries. Tools like HBP 3.0 matter because translating a genetic hit into therapeutic or clinical relevance typically requires navigating five or more disconnected databases. By embedding clinical practice guideline context as a graph layer alongside population-scale frequency data and drug-discovery annotations, HBP 3.0 reduces that friction meaningfully for cardiologists and geneticists alike.
That said, this preprint — not yet peer-reviewed — describes a database and interface update rather than a novel biological discovery, so its impact depends heavily on adoption, data-currency maintenance, and community validation of its interpretive boundaries. Researchers should verify source-level provenance independently before clinical application. Editorially, this is an infrastructure advance: incremental in concept but potentially high-leverage if widely adopted.
