Talk Title:
Mutation discovery in cancer using next generation sequencing and probabilistic models

November 26, 2009, 6:00pm **PLEASE NOTE THE DATE CHANGE**

Molecular Oncology Department, BC Cancer Agency

Sohrab Shah

The advent of next generation sequencing (NGS) has propelled the field of cancer
genomics forward such that it is now cost-effective to interrogate entire genomes or
transcriptomes of clinical tumor samples for the presence of somatic mutations: often
the key driver genomic alterations in tumorigenesis. Since the number of data points
produced by NGS experiments is in the billions, variant discovery is necessarily a
computational exercise. I will describe the development of novel computational methods
for the discovery of mutations from NGS, based on probabilistic models. I will present
results of applying these approaches in two recent studies in ovarian and breast cancer:
namely the discovery of a novel recurrent and defining mutation in the FOXL2 gene in
granulosa cell tumours of the ovary and the first description of mutational evolution of a
breast cancer seen at nucleotide resolution.
