SureSeq myPanel™ is a regularly updated, expert-curated library of pre-optimised cancer panel content for you to select from. Simply mix and match the gene, exonic or intronic content you need to create an NGS cancer panel that meets your exact requirements.
Our unique panel design coupled with hybridisation-based enrichment offers unparalleled coverage completeness and uniformity. This allows the accurate detection of difficult to sequence, low-frequency variants and minimises the requirement for supplementary fill-in with Sanger sequencing.
Getting started with your SureSeq myPanel NGS Custom Panel could not be simpler, find out more in this video…

Mutations in the CEBPA gene are among the most common molecular alterations in AML and bear important significance. Sequencing of the CEBPA gene is often hampered by a repetitive nucleotide sequence and a high GC-rich content, which can lead to technical challenges in assay design, requiring a supplementary fill-in with Sanger sequencing. OGT’s expert bait design overcomes these issues, offer a high level of uniformity coverage for a notoriously difficult gene to sequence.

The CALR gene is commonly mutated in various myeloproliferative neoplasms (MPNs). It is critical to identify key CALR indels (types 1 and 2 causing a frameshift) as well as increasingly recognised point mutations in this gene. OGT’s expert bait design offers excellent coverage uniformity across low-complexity regions with low nucleotide diversity (such as CALR exon 9), compared to other commercially available bait designs, which suffer from a considerable dip in coverage.

The BCR-ABL gene fusion is formed following a balanced translocation of chromosome 9 and 22, generating the Philadelphia chromosome, a hallmark of CML. Combine SNV and indel detection with BCR-ABL translocation content and replace multiple assays with a single streamlined NGS workflow for a more comprehensive picture of all your samples.
Figure 3: BCR-ABL translocation reported in Interpret. Split-reads covering both BCR (left panel) and ABL1 (right panel) are detected, indicative of the BCR-ABL gene fusion.
Figure 4: In this example, two translocations are present, with both BCR-ABL1 (chr22:23,632,850/chr9:133,643,198) and ABL1-BCR (chr9:133,643,072/chr22:23,632,613) translocations identified in the CML cell line JK-1. The breakpoints identified by NGS were found to match the coordinates reported in the literature (ref 1).
Partial tandem duplications in KMT2A (MLL), frequently observed in AML, are notoriously difficult to detect due to their size, often spanning multiple exons. With OGT’s expertise in hybridisation-based panel design, your SureSeq myPanel offers robust detection of all sizes of KMT2A-PTDs, alleviating the burden of running multiple assays (Figure 5).

We were delighted with the performance of the SureSeq panel. It showed complete concordance with our other techniques, detecting all known mutations with excellent sensitivity down to 1% [MAF (minor allele frequency)], including, in one case, a JAK2 V617F mutation which was not detected by ddPCR due to a second mutation under the primer. The panel also demonstrated mutations in other genes in samples with low level JAK2 V617F and good correlation between allele frequencies and quantitative analysis by ddPCR. We are planning to adopt the panel in the near future.
