SOAPsv

SOAPsv detects structural variations from whole-genome de novo assembly of second-generation sequencing reads to identify insertions, deletions, inversions and precise breakpoints for mapping structural variation across genomes.

Key Features:

• Assembly-based detection: Uses whole-genome de novo assembly of second-generation sequencing reads to detect structural variants.
• Size range: Detects small- and intermediate-size homozygous variants in the 1–50 kilobase (kb) range.
• Variant types: Identifies insertions, deletions, inversions and determines precise breakpoints.
• Complex rearrangements: Resolves complex rearrangements that are not accurately detected by other methods.
• Performance on population data: Identified 277,243 SVs (1–23 kb) in 106 individuals from the 1000 Genomes Project.
• Accuracy metrics: Reports a false-positive rate <6% and false-negative rate <10% in assembleable genomic regions.
• Validation: Results validated through computational and experimental techniques.
• Demonstrated datasets: Applied to and demonstrated on Asian and African genomes.

Scientific Applications:

• Population-scale SV discovery: Enables discovery of structural variants across cohorts such as the 1000 Genomes Project.
• Comparative genomics: Maps SVs across diverse genomes, including Asian and African samples.
• Genetic diversity analysis: Facilitates assessment of the contribution of SVs to human genetic variability, potentially exceeding that of SNPs.
• Breakpoint-level studies: Supports high-resolution analysis of breakpoints and complex rearrangements for functional and evolutionary studies.

Methodology:

Performs whole-genome de novo assembly of second-generation sequencing reads and detects structural variants (insertions, deletions, inversions) with precise breakpoint identification.
