Title:
Harnessing Long-Read Sequencing and Imaging Technology for Structural Variant Characterization
Abstract:
Structural variants (SVs) represent a significant component of human genomic diversity and disease susceptibility, yet their comprehensive characterization has been hindered by limitations of short-read sequencing technologies. Leveraging long-read sequencing of samples from the 1000 Genomes Project, our recent work uncovered approximately 200,000 sequence-resolved SVs, including complex events such as retrotransposon-mediated transductions, and a diversity of homology-mediated rearrangements. My talk will present the advancements made possible by the population-wide SV resource generated, including its relationship for elucidating the genetic basis of human disease. Furthermore, our exploration of inversion polymorphisms has revealed novel insights into their association with genomic instability and predisposition to complex disorders. By characterizing polymorphic inversions across 41 genomes, we have measured their recurrence linked to flanking segmental duplications, emphasizing the mutational burden carried by recurrent inversions. To foster our work on SVs, we have recently developed the MAGIC platform, a novel technology that integrates real-time live-cell imaging, machine learning, and single-cell genomics to unravel the mechanisms of de novo chromosomal rearrangements. By systematically tracking chromosomal aberrations over successive cell cycles, MAGIC enables us to establish baseline rates of chromosomal instability and elucidate the roles of DNA double-strand breaks and dicentric chromosomes in driving complex chromosomal abnormalities.

Following the PhD, he pursued postdoctoral research at Yale University, USA. In October 2008, he returned to EMBL as a group leader. Since 2016, he has held the position of Senior Scientist at EMBL, with a joint appointment at the European Bioinformatics Institute (EMBL-EBI). In addition, he has been a Senior Scientist in the Molecular Medicine Partnership Unit and, since 2020, Head of Data Science. Jan Korbel has been an ERC Investigator since 2014 and is also a faculty member of the ELLIS Unit.
