Abstract
“Transcriptomic Structural Variation Detection”
Genomic structural variants that affect expressed transcripts have been implicated in cancer and other diseases. However, detecting these transcriptomic structural variants is challenging computationally. I will describe several computational methods for identifying structural variants from short-read RNA sequencing data. These methods come in two variations. The first type identifies a set of genomic rearrangements that best explains the observed reads and does so in an annotation agnostic way. This allows for the detection of both fusion genes and rearrangements that are not fusions genes but that nevertheless change the sequence of a transcript. The second type of method I will describe identifies coverage anomalies, defined as regions of transcripts where the observed read coverage differs significantly from what one would expect given a sequencing bias model. This is joint work with Cong Ma, Yutong Qiu, and Mingfu Shao.
