HIVID2

HIVID2 identifies viral integration sites in host genomes by remapping paired-end reads and leveraging split and discordant chimeric reads to improve breakpoint detection specificity and sensitivity.

Key Features:

• Paired-End Combination (PE-combination): Processes potentially integrated paired-end reads and remaps resulting sequences onto reference genomes to consolidate evidence for integrations.
• Split and discordant chimeric read analysis: Utilizes split and discordant chimeric reads to pinpoint integration breakpoints with high confidence.
• Enhanced specificity and sensitivity: Demonstrates improved specificity and sensitivity over HIVID and other existing tools, predicting breakpoints closer to actual integrations as evaluated on simulated and real datasets.

Scientific Applications:

• Discovery of novel integration breakpoints: Enables identification of previously unreported viral integration breakpoints in host genomes.
• Cancer genomics (cervical cancer): Identified integration sites within cervical cancer–related genes FHIT and LRP1B with corroboration from protein expression data.

Methodology:

Remapping of paired-end sequences to reference genomes using the PE-combination approach and interrogation of split and discordant chimeric reads to identify integration breakpoints.
