Probes: PDGFRb (5q32), BCR/ABL1-ASS1 t(9;22), JAK2 (9p24.1), EPOR (19p13.2) and CRLF2 (Xp22.33/Yp11.32) are included in the ALL FISH (Ph-like) Panel. Probes may be ordered separately.
Disease(s): Philadelphia chromosome (Ph-like) acute lymphoblastic leukemia (ALL), B lymphoblastic leukemia/lymphoma.
Note: STAT processing is available by request for BCR-ABL1. Note STAT along with MD contact name and phone number to receive STAT results.
The ALL FISH Panel (Ph-like) detects cytogenetic abnormalities commonly associated with Philadelphia chromosome (Ph-like) acute lymphoblastic leukemia (ALL). Patients with Ph-like B-ALL are associated with an unfavorable prognosis, but may potentially be amenable to inhibition with select tyrosine kinase inhibitors.
- Bone Marrow Aspirate: 1-2 mL in sodium heparin tube. EDTA tube is acceptable.
