Multi-omics integration in Brugada syndrome reveals cooperative networks of genes, miRNAs, and proteins driving the disease phenotype, offering potential new diagnostic and prognostic biomarkers.
Supports multi-omics networks in Brugada syndrome; leaves open whether integrated profiling aids diagnosis or risk stratification.
PURPOSE: The Brugada syndrome (BrS) is a severe inherited cardiac disorder. Given the high genetic and phenotypic heterogeneity of this disease, three different "omics" approaches are integrated in a synergic way to elucidate the molecular mechanisms underlying the pathophysiology of BrS as well as for identifying reliable diagnostic/prognostic markers. EXPERIMENTAL DESIGN: The profiling of plasma Proteome and MiRNome is perfomed in a cohort of Brugada patients that were preliminary subjected to genomic analysis to assess a peculiar gene mutation profile. RESULTS: The integrated analysis of "omics" data unveiled a cooperative activity of mutated genes, deregulated miRNAs and proteins in orchestrating transcriptional and post-translational events that are critical determining factors for the development of the Brugada pattern. CONCLUSIONS AND CLINICAL RELEVANCE: This study provides the basis to shed light on the specific molecular fingerprints underlying BrS development and to gain further insights on the pathogenesis of this life-threatening cardiac disease.
