Structural Variation Detection by Proximity Ligation from FFPE Tumor Tissue

GenomeWebinar

Instructor, Department of Pathology & Biomedical Data Science,
Stanford Medical School

Director of Product Management, Dovetail Genomics

This webinar will discuss a proximity ligation-based method for studying structural variation in formalin-fixed paraffin-embedded (FFPE) tissue.

FFPE tissue produces highly fragmented, low-molecular weight nucleic acids, presenting a principal challenge to identifying relevant genetic variants with tumor sequencing. This sub-optimal input specimen was previously not thought to contain long-range (Mbp+) information needed to accurately and robustly identify balanced and unbalanced large-scale structural variation and phasing from these specimens.

This webinar will highlight a proof-of-concept study for using Hi-C chromosome conformation capture methodology for FFPE tissue, called Fix-C, which yields phased read pairs spanning distances up to full chromosomes and enables unambiguous structural variation detection and variant phasing in archival specimens.

Join this webinar to:

  • Learn how proximity ligation technology works and proven applications for this multi-dimensional NGS datatype from structural variation detection to genome assembly
  • See how proximity ligation overcomes the main challenge of highly fragmented DNA for studying structural variation from FFPE samples with data from a proof of concept study
