DOCK8-JAK2 Fusion FISH Probe

The DOCK8-JAK2 Fusion FISH Probe is used to confirm a fusion of the DOCK8 and JAK2 genes. The fusion of the DOCK8 and JAK2 genes has been associated with Kidney Renal Clear Cell Carcinoma. These probes are FISH confirmed on normal peripheral blood in both interphase nuclei and metaphase spreads before shipment. Typical turnaround time for this product is 7-14 days after purchase.

** This product is for in vitro and research use only. This product is not intended for diagnostic use. Please note that both genes fall on the same chromosome and inter-chromosomal detection may be difficult to detect depending on the genes proximity to one another. Please consult our support staff before ordering this product to ensure that the probe can be designed to meet your specific needs.

JAK2 Gene Summary

This gene product is a protein tyrosine kinase involved in a specific subset of cytokine receptor signaling pathways. It has been found to be constituitively associated with the prolactin receptor and is required for responses to gamma interferon. Mice that do not express an active protein for this gene exhibit embryonic lethality associated with the absence of definitive erythropoiesis. [provided by RefSeq, Jul 2008]

Gene Name: Janus Kinase 2

Chromosome: CHR9: 4985244 -5128183

Locus: 9p24.1

DOCK8 Gene Summary

This gene encodes a member of the DOCK180 family of guanine nucleotide exchange factors. Guanine nucleotide exchange factors interact with Rho GTPases and are components of intracellular signaling networks. Mutations in this gene result in the autosomal recessive form of the hyper-IgE syndrome. Alternatively spliced transcript variants encoding different isoforms have been described.[provided by RefSeq, Jun 2010]

Gene Name: Dedicator Of Cytokinesis 8

Chromosome: CHR9: 214864 -465259

Locus: 9p24.3

JAK2 double minutes with resultant simultaneous amplification of JAK2 and CD274 in a therapy-related myelodysplastic syndrome evolving into an acute myeloid leukaemia

Amplification with double minutes (DM) of the JAK2 gene could potentially accelerate the progression of leukemia. FISH analysis was used in conjunction with SNP microarray to observe the effects of the amplification. FISH was performed using our JAK2 probe, showing multiple copies of JAK2 residing on the DMs. It was concluded that amplification of JAK2 could indeed contribute to progression of the disease.

First Case of Double T-Cell Receptor Alpha/Delta Rearrangements of t(11;14) and inv(14) and Subsequent JAK2 Rearrangement in a Patient with T-Cell Acute Lymphoblastic Leukemia

T-cell acute lymphoblastic leukemia (T-ALL) is characterized by translocations of oncogenic transcription factor genes and T-cell receptor loci. This study reported the first case of T-ALL with TCR alpha/delta (TRA/D) locus rearrangements associated with t(11;14)(p13;q11.2), inv(14)(q11.2q32), and clonal evolution of JAK2 rearrangement. Our JAK2 break-apart probe was used to detect a novel JAK2 translocation, t(8;9)(p22;p24), in the subject under study. As the patient tested negative for JAK2 rearrangements at diagnosis, the translocation must have developed during disease progression.

The diagnostic challenges and clinical course of a myeloid/lymphoid neoplasm with eosinophilia and ZBTB20-JAK2 gene fusion presenting as B-lymphoblastic leukemia

JAK2 rearrangements are hallmarks of both Ph-Like B-cell ALL and myeloid/lymphoid neoplasms with eosinophilia and gene rearrangements (MLN-EGR). This study used our JAK2 break-apart probe to discover a new JAK2 fusion - ZBTB20/JAK2 - in a patient with B-ALL with eosinophilia. The team found that her disease originated with a JAK2-rearranged myeloid neoplasm that developed into B-ALL.
