SureSeq™ CLL + CNV Panel
The SureSeq CLL + CNV Panel has been designed in collaboration with recognised cancer experts to detect 12 key genes and 5 chromosomal regions implicated in CLL progression.
Chronic lymphocytic leukaemia (CLL) is the most common type of leukaemia in adults. A wide variety of chromosomal abnormalities are associated with CLL, ranging from single nucleotide variants (SNVs) and insertions/deletions (indels) up to large copy-number variations (CNVs), including trisomies.
The SureSeq CLL + CNV Panel has been designed in collaboration with recognised cancer experts to detect 12 key genes and 5 chromosomal regions implicated in CLL progression (Table 1). The SureSeq CLL + CNV Panel alleviates the burden of running multiple assays and streamlines your CLL research to deliver a comprehensive genomic profile for each CLL sample using a single workflow.
The SureSeq CLL + CNV Panel offers:
- Unparalleled uniformity and high depth of coverage - detect low-frequency SNVs and indels
- CNV detection ranging from loss of single exons to full chromosome arms and
trisomy 12 - profile your samples for CNVs in the 5 most commonly aberrant regions in CLL
- Time savings - replace multiple assays with a single NGS panel, increasing throughput and
reducing turnaround time
- Complimentary data analysis software - analyse your data with Interpret, OGT’s powerful and
easy-to-use analysis solution for accurate identification of all variants and CNVs
Contains the latest evidence-based content
Investigating both chromosomal aberrations and SNVs/indels is imperative to advance research into CLL progression and treatment. Structural abnormalities are common in CLL and found in more than 80% of CLL cases, the most frequent being del(13q), del(11q), del(17p), del(6q) and trisomy 121. Some of these CNVs cover important tumour suppressors, such as del(17p) resulting in the loss of the TP53 gene. More recently, other genes have also been found to be mutated in CLL, including NOTCH1, SF3B1, MYD88 and BIRC3, adding to the genomic complexity of this leukaemia2.
Due to this genetic heterogeneity, current analysis strategies for CLL require multiple methods to obtain a comprehensive genetic picture, often using microarray or fluorescence in situ hybridisation (FISH) to detect structural abnormalities in combination with NGS for somatic variants. With OGT’s SureSeq CLL + CNV Panel, you can now obtain a more complete understanding of the genetic makeup of CLL progression in each sample using a single assay.
Table 1: The SureSeq CLL + CNV Panel targets the 5 most common chromosomal regions implicated in CLL and 14 genes, including 2 genes and 24 SNPs for easy sample tracking.
Superior coverage uniformity allowing reliable variant and somatic CNV detection
OGT’s expert bait design delivers outstanding uniformity and depth of coverage, offering confident detection of low frequency SNVs and indels down to 1% minor allele frequency (MAF) in 14 genes (Figure 1), including 2 genes and 24 SNPs to allow for easy sample tracking3.
Figure 1: Illustration of the excellent uniformity and high depth of coverage allowing confident detection of (A) a SF3B1 exon 15 hotspot variant Lys700Glu with 4.8% allele frequency and (B) a TP53 exon 4 frameshift deletion (TP53 c.124del) with frequency 38.9%.
The SureSeq CLL + CNV Panel covers the 5 most common CNVs in CLL and enables detection down to 10% MAF, corresponding to 20% tumour content. Compared to array data, often considered the gold standard for CNV detection, the events reported with the SureSeq CLL + CNV Panel were 100% concordant, even in genomic regions containing multiple aberrations (Figures 2 - 3). More so, facilitated by OGT’s excellent bait design, loss-of-heterozygosity (LOH) can be identified. With a CNV size detection range from single exon to whole gene, up to complete loss of a chromosomal arm and whole chromosome gains (trisomy 12), your data provides a more comprehensive genetic picture for each sample from a single assay.

Complimentary Interpret software
Interpret is OGT’s powerful and easy-to-use data analysis solution, facilitating analysis and visualisation of a wide range of somatic variants and structural aberrations. Designed to work seamlessly with all SureSeq panels, Interpret perfectly complements the SureSeq CLL + CNV Panel, delivering fast and accurate detection of all SNVs, indels, LOH and CNVs covered by the panel. Following detection, all events can be readily visualised in the user-friendly variant browser, for an effortless translation of all your CLL data into meaningful results (Figure 4).
Figure 4: Following analysis, all variants and CNVs are visualised for easy interpretation in OGT’s Interpret. In this example a trisomy 12 is detected, showing a reliable gain call across the whole chromosome.
