Real-time RT-PCR for quantitative detection of t(9;22) BCR-ABL1 fusion transcripts that result in major p210 (E13, E14) or minor p190 (E1) fusion proteins with option to add p230 detection (micro or atypical variant). p230 testing may be ordered as a stand-alone test. For p210 and p190, analytical sensitivity is 1 tumor cell in 100,000 normal cells, log reduction score and percent abnormal are reported, and longitudinal data will appear as a NeoTRACK Result on the report. For p230, results are reported as percent abnormal.

Detects ABL1 kinase domain mutations in patients with BCR-ABL1-positive chronic myelogenous leukemia (CML) or acute lymphoblastic leukemia (ALL). RNA is isolated, reverse transcribed to complementary DNA (cDNA), and the DNA sequence of targeted regions of ABL (exons 4, 6-7) is determined using next-generation sequencing (NGS) technology. Analysis includes detection of the common T315I mutation.

Includes analysis of JAK2 V617F, JAK2 Exon 12-14, CALR exon 9, and MPL exon 10. Testing is performed on plasma for increased sensitivity whenever possible. Tests may also be ordered individually.

Detects the V617F mutation. V617F testing may be ordered as part of the MPN Molecular Panel.

RT-PCR and bi-directional sequencing to detect non-V617F mutations in exons 12-14 and most of exon 15, corresponding to the majority of the JAK2 pseudokinase domain. Exon deletion mutations are detectable. Testing is performed on plasma for increased sensitivity whenever possible. V617F analysis is recommended before or concurrently with this test. Exon 12-14 Mutation Analysis may be ordered separately, with concurrent V617F testing as part of the MPN Molecular Panel.

Bi-directional sequencing of exon 9 of the CALR (calreticulin) gene with fragment length analysis for enhanced detection of low levels of insertion/deletion mutations. This test may be ordered separately or as part of the MPN Molecular Panel.

Bi-directional sequencing of exon 10 of the MPL gene to detect all possible mutations at the W515 and S505 codons, and other mutations throughout the exon. Testing is performed on plasma for increased sensitivity whenever possible. This test may be ordered separately or as part of the MPN Molecular Panel.

Available as global test only. Markers are VB1, VB2, VB3, VB4, VB5.1, VB5.2, VB5.3, VB7.1, VB7.2, VB8, VB9, VB11, VB12, VB13.1, VB13.2, VB13.6, VB14, VB16, VB17, VB18, VB20, VB21.3, VB22, and VB23 (24 markers). Two additional T-cell markers are used to identify the population of interest and the markers vary from case to case.

Detection of clonal IgH gene rearrangements by PCR of IgH framework regions 1, 2, 3 and joining regions. In addition, Ig Kappa gene rearrangement analysis is performed using specific oligonucleotides recognizing the Vk, intragenic and Jk regions.

RT-PCR and bi-directional sequencing of the variable region of the immunoglobulin heavy chain for detection of mutation from germline sequence. The mutated VH gene family is identified in positive reports (>3% sequence deviation). Mutation may not be detectable in specimens containing < 10% clonal B-cells.

Detection of internal tandem duplication and exon 20 tyrosine kinase domain (TKD) mutations using bi-directional sequencing. Positive results identify specific TKD mutations or report ITD results quantitatively as percent abnormal ITD peak. Testing may be performed on plasma to increase sensitivity.

PCR and fragment analysis of exon 12 of the NPM1 gene to detect small insertion mutations specific to AML. Positive results are reported quantitatively as percent abnormal DNA. Testing may be performed on plasma to increase sensitivity.

Detection of internal tandem duplication and exon 20 tyrosine kinase domain (TKD) mutations using bi-directional sequencing. Positive results identify specific TKD mutations or report ITD results quantitatively as percent abnormal ITD peak. Testing may be performed on plasma to increase sensitivity.

PCR and fragment analysis of exon 12 of the NPM1 gene to detect small insertion mutations specific to AML. Positive results are reported quantitatively as percent abnormal DNA. Testing may be performed on plasma to increase sensitivity.

Bi-directional sequencing of KIT exons 8, 9, 11, 13 and 17 for detection of activating mutations including the common mutation D816V. For solid tumors, tumor enrichment is performed before extraction. In hematological disease, testing may be performed on plasma to increase sensitivity.

Real-time RT-PCR for quantitative detection of the t(15;17) PML-RARA fusion transcript. Both long and short isoforms of the fusion transcript are detected. Positive results identify the isoform and quantify it as a ratio with the amount of transcript from a normal control gene. Analytical sensitivity is 1 tumor cell in 100,000 normal cells.

Bi-directional sequencing of the relevant coding region and fragment analysis for detection of sequence variant and internal tandem duplication mutations. The SNP genotype at rs34529039 is reported. Testing is performed on plasma for increased sensitivity whenever possible.

Detects the MLL partial tandem duplication (PTD) between exons 2 and 8 in the MLL gene.
