SOAPfusion

SOAPfusion identifies fusion transcripts from paired-end RNA-Seq reads to detect gene fusions relevant to cancer genomics and other genetic disorders.

Key Features:

• Direct Fusion Identification: Processes paired-end RNA-Seq reads to directly identify fusion candidates rather than locating candidate regions first.
• High Sensitivity: Demonstrates sensitivity of 93% or higher in reported evaluations.
• Low False-Positive Rate: Maintains a reported false-positive rate of 1.36% or less.
• Performance at Low Coverage: Retains high detection accuracy at sequencing depths as low as 10×.
• Empirical Validation: Identified seven novel fusion genes in Universal Human Reference RNA (UHRR) samples that were validated by reverse transcription–PCR and Sanger sequencing.
• Multiple-Mapping Handling: Implements verification steps that address multiple mappings common in fusion detection.

Scientific Applications:

• Cancer Genomics: Detection of gene fusions implicated in tumorigenesis and potential therapeutic targets.
• Large-Scale Transcriptomic Studies: Discovery of novel fusion transcripts across cohorts using RNA-Seq data, including low-coverage datasets.

Methodology:

Processes paired-end RNA-Seq reads to directly identify fusion candidates, applies verification steps, and handles multiple mappings to confirm detected fusions.
