PVAAS

PVAAS identifies single nucleotide variants (SNVs) associated with aberrant alternative splicing by integrating variant detection and splicing analysis from RNA-seq data.

Key Features:

• Simultaneous analysis: Integrates detection of aberrant splicing events with identification of SNVs from RNA-seq data in a single analysis.
• Aberrant splicing detection: Detects deviations from expected splicing patterns using RNA-seq-derived transcriptome data.
• Variant integration and calling: Supports incorporation of pre-existing variant lists or performs variant calling directly from RNA-seq reads.
• Association assessment: Evaluates statistical significance of associations between identified SNVs and aberrant splicing events.
• Three-step workflow: Implements a three-step process of splicing detection, variant integration/calling, and statistical association testing.

Scientific Applications:

• Disease research: Investigating how specific SNVs contribute to diseases characterized by aberrant splicing, such as cancers and genetic disorders.
• Functional genomics: Exploring the functional consequences of genetic variation on gene expression regulation via alternative splicing mechanisms.
• Transcriptome analysis: Linking SNVs to alterations in splicing patterns to enhance interpretation of RNA-seq-based transcriptomic studies.

Methodology:

Identify aberrant splicing events from RNA-seq data; integrate or call SNVs from RNA-seq or pre-existing variant lists; assess statistical significance of SNV–splicing associations.
