One of the challenges in cancer research is the high level of genetic complexity and tumour heterogeneity.
Research that generates detailed information about the genetic profile of each individual tumour will further our understanding and may be used in the future to guide treatment strategies1 .
NGS has enabled the simultaneous study of multiple mutations in high-penetrance cancer predisposition genes. However, tissue biopsies are typically archived as formalin-fixed, paraffin embedded (FFPE) blocks which can significantly compromise the quality and amount of nucleic acids available for genomics research.
To overcome these issues, we have used the SureSeq™ FFPE DNA Repair Mix, in combination with a hybridisation-based NGS custom enrichment panel, the SureSeq Ovarian Cancer Panel (Table 1) to identify somatic variation in key DNA repair genes associated with ovarian cancer.

To evaluate the application of a hybridisation-based approach we:
