Structural variant calling using third-generation sequencing data Thema der Disputation:
Genome graphs and their application in pangenomics
Abstract:
Since its first publication in 2001, the human reference genome has transformed the biological and medical sciences. Acting as the baseline for most genetic analyses it has enabled numerous discoveries but at the same time imposed unique limitations and biases. In particular, analyses using a single linear reference genome are blind to the considerable amount of human genome sequence missing from the reference and its associated variants and phenotypes. In this talk, I will present pangenomic approaches as an alternative that can capture the genetic diversity in human and other species more completely. Instead of choosing a single genome as the reference, pangenomes model the full set of genomic elements present in a population. After introducing different representations of pangenomes I will focus on genome graphs because they can model both simple and complex genomic variation. My talk will cover 1) the basic elements of genome graphs, 2) two different methods for genome graph construction and 3) the application of genome graphs for the genotyping of structural variants (SVs).
