BACKGROUND: Long-read sequencing and multi-omic analytical frameworks are increasingly being adopted in rare disease diagnostics. However, clinical workflows comprehensively integrating these methodologies remain uncommon. OBJECTIVE: This study aimed to assess the potential and limitations of integrating long-read genomic, transcriptomic, and proteomic analyses to characterize complex structural variants. METHODS: Two unrelated patients presenting with dystonia and comorbid neurological features underwent nanopore-based long-read DNA sequencing. In patient 1, complementary transcriptomic and proteomic analyses were performed. RESULTS: The workflow enabled the identification and characterization of two pathogenic complex structural variants: a homozygous AluY-mediated inversion disrupting PANK2, underlying neurodegeneration with brain iron accumulation (patient 1), and a heterozygous de novo 16p13.3 duplication-triplication event associated with an atypical dystonia-parkinsonism phenotype (patient 2). CONCLUSIONS: Our findings underscore the diagnostic potential of integrated long-read and multi-omic approaches for complex structural variant characterization, while illustrating persistent limitations of automated pipelines and highlighting unpredictable relationships between genomic, transcriptomic, and proteomic findings. © 2026 The Author(s).
