Sequencing for Discovery of Candidate Mutations in Lymphoma Transcriptomes
This project involves identifying and characterizing the range of mutations found in lymphoma tumours. Once identified, specific mutations may be shown to effect or be associated with response to treatment, patient outcome and survival, or be useful as a target for anti-cancer drug development.

We will collect fresh-frozen tumour biopsy material and DNA from normal non-cancerous tissues from a group of patients with diffuse large B cell lymphoma (DBCL). Each sample of cells will be subjected to genomic, cytogenetic and functional analyses involving:
- A whole transcriptome “shotgun” approach that has the potential to identify both point mutations and novel transcript structures, such as transcriptional fusions that might arise as a consequence of genome rearrangements
- Computational identification of candidate mutations
- Karyotypic and more detailed cytogenetic characterization using FISH, aCGH and SNP CHIP analyses
- Validation studies utilizing matched normal samples
This research will result in a list of somatic mutations, both large and small scale, that will be likely suspects in driving the development of lymphoid cancers and in the progression of the disease.
