Deregulation of the proto-oncogene, MET, confers an aggressive phenotype in a variety of cancers. MET deregulation can be driven be gene amplification, overexpression, single nucleotide variants (SNVs), exon 14 skipping and fusions. We developed target enrichment kits for next-generation sequencing (NGS) to sensitively detect all types of MET aberrations from low-input clinical sample types, such as FFPE samples.


VariantPlex™ and FusionPlex™ kits were developed based on Anchored Multiplex PCR (AMP™) to generate NGS libraries from DNA and RNA, respectively. Probes were designed to cover the MET gene and transcript, enabling detection of copy numbers and SNVs by VariantPlex, and fusions, exon skipping and expression by FusionPlex kits.


VariantPlex and FusionPlex kits enabled detection of MET amplifications, confirmed by FISH, and the resulting overexpression in FFPE samples. Exon 14 skipping was also detected in FFPE and in cells, concomitant with splice site SNVs, and verified by RT-PCR. Lastly, we detected a GTF2I:MET fusion in an FFPE sample and a Y1253D activating point mutation in cells.


These results demonstrate the utility of Archer VariantPlex and FusionPlex kits to detect all types of MET mutations by NGS. Enhanced detection sensitivity enabled by AMP technology permits confident detection of mutations from low-input clinical samples.

Thyroid and lung cancers are driven by multiple types of genetic aberrations, including single nucleotide variants (SNVs), insertions and deletions (indels), copy number variants (CNVs) and fusions. Next generation sequencing (NGS) of target-enriched libraries is a highly sensitive and scalable method to detect these mutations. Anchored Multiplex PCR (AMP™) is a target enrichment strategy that uses unidirectional gene-specific primers and molecular barcoded adapters ligated to DNA ends for amplification. This enables amplification of both known and unknown mutations within target regions and increases coverage of target regions.


We developed AMP-based comprehensive thyroid and lung (CTL) assays, VariantPlex™ and FusionPlex™ CTL, with probes covering relevant genes in thyroid and lung cancers.


Our data show that parallel interrogation of DNA and RNA using VariantPlex and FusionPlex CTL assays, respectively, enables simultaneous detection of known and unknown SNVs, indels, CNVs and fusions from low-input clinical sample types. Furthermore, we show that characterization of gene expression, including detection of splice variants, expression imbalances and whole gene expression levels provides orthogonal verification of detected mutations.


These results demonstrate the utility of CTL assays to simultaneously and sensitively detect all types of mutations in clinically relevant genes in thyroid and lung cancer samples.

Sensitive detection of copy number variants from FFPE samples by Anchored Multiplex PCR-based next-generation sequencing

Copy number variations (CNVs) impact more of the cancer genome than all other mutation types combined. Next-generation sequencing (NGS) is an invaluable tool to detect CNVs. However, routine formalin-fixed paraffin-embedded (FFPE) storage of clinical specimens severely damages DNA, limiting detection sensitivity. We developed a target enrichment strategy based on Anchored Multiplex PCR (AMP™) to enhance NGS-based detection sensitivity of CNVs.


AMP generates libraries for NGS by amplifying degraded DNA fragments, thereby increasing read coverage of target regions. We developed the Archer™ VariantPlex™ Solid Tumor kit with AMP probes to amplify 43 CNVs associated with a variety of carcinomas. We also developed the PreSeq™ DNA QC Assay to determine the integrity of genomic DNA prior to library preparation.


By screening 139 FFPE samples, we show that NGS-based CNV detection sensitivity is primarily driven by the integrity of the input genomic DNA. Using optimal input amounts of genomic DNA, the VariantPlex Solid Tumor kit enabled detection of CNVs as low as 2-fold in FFPE samples and in samples with as low as 3% tumor cellularity.


These results demonstrate that AMP-based NGS accurately detects low-level CNVs in genomic DNA from low-input clinical samples and from samples with low tumor cellularity.
