Rearrangements of the T-cell receptor alpha/ delta TRA/D are recurrent and immature T-cell neoplasms. Many of these TRA/D rearrangements are cryptic at the conventional cytogenetic level and therefore are detected mainly by molecular testing and FISH. The majority of these rearrangements are translocations that juxtapose a transcrption factor gene to the TRA/D locus leading to its aberrant expression in developing thymocytes.

1-3 mL bone marrow in transport medium or 3-5 mL whole blood in a
sodium heparin tube (green top, dark/royal blue top, tan top).
Formalin fixed paraffin embedded tumor biopsy or 5 mm x 5 mm
fresh tumor biopsy in transport medium.

Clinical history/reason for referral is required with test order.
Prior therapy and transplant history should be provided with test
order.

SPECIMEN VIABILITY DECREASES DURING TRANSIT. SEND SPECIMEN TO
TESTING LAB FOR VIABILITY DETERMINATION. DO NOT REJECT.
