qBiomarker Somatic Mutation PCR Arrays are intended for molecular biology applications. These products are not intended for the diagnosis, prevention, or treatment of a disease.


Performance

qBiomarker Somatic Mutation PCR Arrays show a high degree of sensitivity even with formalin-fixed paraffin-embedded (FFPE) samples (see figures "High degree of sensitivity" and "Sensitivity of qBiomarker Somatic Mutation PCR Arrays with FFPE samples").

qBiomarker Somatic Mutation PCR Arrays have utility in the detection of mutations in cell lines or research samples, which is critical for toxicological, drug development, and cancer studies (see figure "Profiling of common cancer cell lines for somatic mutation status").

Principle
Real-time PCR is the most sensitive and reliable method for the detection of DNA mutations. By combining allele-specific amplification and hydrolysis probe detection, qBiomarker Somatic Mutation real-time PCR assays have been developed which can detect as few as 1% somatic mutations in the background of wild-type genomic DNA. Allele-specific amplification is achieved by Amplification Refractory Mutation System (ARMS) technology, which is based on the discrimination by Taq polymerase between a match and a mismatch at the 3’ end of the PCR primer (see figure "Principle of ARMS technology").
Procedure

Simply mix the DNA template with the ready-to-use PCR mastermix, aliquot equal volumes to each well of the same plate, and then run the real-time PCR cycling program. qBiomarker Somatic Mutation PCR Arrays are compatible with all ABI, Bio-Rad, Eppendorf, Roche, and Stratagene instruments.

qBiomarker Somatic Mutation PCR Arrays are available in 96-well and 384-well plates and are used to detect mutations related to a disease state or pathway, plus gene copy number controls for normalization. Each qBiomarker Somatic Mutation PCR Array also includes control elements for general PCR performance.

Myelodysplastic Syndromes (MDS) qBiomarker Somatic Mutation PCR Array
Introduction
The Human Myelodysplastic Syndromes (MDS) qBiomarker Somatic Mutation PCR Array is a translational research tool that allows rapid, accurate and comprehensive profiling of recurrent somatic mutations in human MDS samples. MDS and related disorders (myelodysplasia) comprise a group of myeloid neoplasms characterized by deregulated, dysplastic blood cell production. Mutations in a number of genes have been implicated in the pathogenesis of MDS, including ASXL1, CBL, DNMT3A, EZH2, IDH1, IDH2, NRAS, RUNX1, TET2, TP53, and the more recently identified mutations in the RNA splicing machinery components SF3B1, SRSF2 and U2AF35. Detection of somatic molecular abnormalities that may cause and maintain MDS is crucial for patient sample stratification in translational research studies. These mutations also warrant extensive investigation to enhance the understanding of carcinogenesis and identify potential drug targets. With its comprehensive content coverage, this array is designed for studying mutations in the context of MDS and has the potential for discovering and verifying MDS biomarkers. The 83 real-time PCR DNA sequence assays included on the array detect the most frequent, functionally verified, and biologically significant mutations in MDS. These mutations were chosen from curated, comprehensive somatic mutation databases and peer-reviewed scientific literature. The simplicity of the product format and operating procedure allows routine somatic mutation profiling in any research laboratory with access to real-time PCR instruments.
Gene List

ASXL1: 5 Assays
Most frequently observed mutations in this gene are C-terminal truncations that lose the interaction domain with RARA, the poly-serine region, and the atypical PHD-type domain. Other truncations also lose part of the NCOA1 interaction domain and a glycine-rich region.

CBL: 4 Assays
The most frequently occurring mutations in this gene reside in its RING-type, or zinc finger-like, domain in an Asp/Glu-rich (acidic) region likely involved in its ubiquitination activity. Other mutations include p.R420Q and p.K382E, which impair CBL-mediated degradation of cell-surface receptors in a dominant-negative fashion, and p.Y371H, which should reduce tyrosine phosphorylation by the insulin receptor.

DNMT3A: 2 Assays
Mutations are frequently observed in the domain conserved among S-adenosylmethionine-dependent methyltransferases superfamily members.

EZH2: 3 Assays
All detected mutations lie in the SET domain responsible for histone lysine methyltransferase activity.

IDH1: 5 Assays
Most of these mutations abolish magnesium binding and alters the enzyme's activity to convert alpha-ketoglutarate into R(-)-2-hydroxyglutarate instead of isocitrate into alpha-ketoglutarate.

IDH2: 7 Assays
These mutations all lie in the substrate binding domain, and one (p.R140Q) is associated with D-2-hydroxyglutaric aciduria.

NRAS: 14 Assays
The mutation assays include the most important NRAS mutations at codons 12, 13, and 61.

RUNX1: 7 Assays
RUNX is the alpha subunit of the core binding factor that is thought to be involved in normal hematopoiesis. Chromosomal translocations involving this gene have been associated with several types of leukemia.

SF3B1: 6 Assays
The most frequently occurring mutations in this gene reside in any one of its 11 HEAT repeats. These domains are possibly protein-protein interaction surfaces or involved in intracellular transport processes.

SRSF2: 3 Assays
Mutations frequently occur at a proline residue in amino acid position 95.

TET2: 2 Assays
The most common variants of this gene are C-terminal truncations missing its two glutamine-rich regions, all of its metal binding site residues, and a phosphoserine and a phosphotyrosine site.

TP53: 19 Assays
The most frequently detected somatic mutations in TP53 are largely composed of DNA-binding domain mutations which disrupt either DNA binding or protein structure.

U2AF35: 4 Assays
Mutations frequently occur at two residues each in different zinc fingers (C3H1-type domains) likely involved in RNA binding.
