Comprehensive profile of all mutations present in the exome
GATCLiquid Oncoexome is the first non-invasive service to provide researchers and clinicians an overview of all protein- coding regions in the genome of a suspected cancer patient.
The cancer exome sequencing tool offers the opportunity to discover novel variants, recurrent or frequent somatic mutations in circulating tumour DNA (ctDNA) in cases where limited information on tumour-associated genome instability exists.
- Tumour exome analysis of plasma ctDNA from a non-invasive blood test, where tissue biopsy is not feasible or recommended
- Examination of all mutations in the coding regions of a suspected cancer patient
- Cancer profiling in cases where limited information on tumour-associated mutations is available
- Discovery of structural variants, novel and common genomic alterations
- Comparison of exomes from tissue biopsy and liquid biopsy samples
- Selection of mutations for further analysis
