The Oncomine BRCA Assay uniquely empowers laboratories to detect all classes of mutations in one NGS workflow, removing the need to employ multiple technologies.
The Oncomine BRCA Assay enables robust performance and reliable, rapid and consistent high-quality results from every sample.
Learn how the Oncomine BRCA Research Assay offers sensitive, specific detection of SNVs, MNVs, indels, and whole-exon, multiple-exon, or entire-gene aberrations.
The Ion Torrent Oncomine BRCA Assay is now available for use on the Ion GeneStudio systems with the Ion Chef Instrument or for use on the Ion Torrent Genexus System.

The associated figures demonstrate the superior performance of the Oncomine BRCA Assay. All exons are 100% covered, with an average of 64 bases of flanking sequence into the introns upstream and downstream of each exon, allowing for over 99% confidence of detecting 5% somatic variants. The uniformity and high read counts ensure high sensitivity and accuracy of both somatic and germline mutation detection, demonstrated with different workflows (and sequencers). The performance has been verified for use on the Ion 530 chips on GeneStudio system and GX5 chip on Genexus system.
Figure 2. 100% exon coverage across both BRCA 1 and BRCA 2 genes, with high uniformity and read counts across all exons, allowing for over 99% confidence of detecting 5% somatic variant.

Figure 3. Superior accuracy in detecting somatic and germline variants that is highly consistent and independent of workflow. At 5% allele frequency, >1,000 SNV and >600 indel variants measured. At 50%, 100% allele frequency, >4,000 SNV and >200 indel variants measured. Positive predictive value (PPV) = true positives/total number of positives. Sensitivity = true positive/(true positives + false positives).
Figure 4. Relative abundance of BRCA exons are plotted. The sample has a deletion in BRCA1 (red) of exons 4–9 (green circle). BRCA2 (blue) has no CNV. The green plot indicates the sample ID amplicons used for normalization.z
