The NeoTYPE AITL/Peripheral T-Cell Lymphoma Profile is performed by the sequencing of all exons in the genes BCL1 (CCND1), IDH1, IDH2, DNMT3A, TET2 and select exons in RHOA.
Angioimmunoblastic T-cell lymphoma (AITL) is a subtype of peripheral T-cell lymphoma (PTCL) and accounts for 20-25% of PTCLs. Peripheral T-cell lymphoma is known as an aggressive group of lymphoid malignancies and represent about 10-15% of non-Hodgkin lymphomas. Frequent mutations have been detected in the genes IDH1/2, DNMT3A, TET2 and RHOA in patients diagnosed with AITL. These mutations may play a role in the pathogenesis of AITL/PTCLs.
- Bone marrow (Preferred): 2 mL in EDTA tube.
- Peripheral blood: 5 mL in EDTA tube.
- FFPE tissue: Paraffin block. Alternatively, send 1 H&E slide plus 5-10 unstained slides cut at 5 or more microns. Please use positively-charged slides and 10% NBF fixative is the recommended fixative. Do not use zinc or mercury fixatives (B5). Highly acidic or prolonged decalcification processes will not yield sufficient nucleic acid to accurately perform molecular studies.
Use cold pack for transport, making sure cold pack is not in direct contact with specimen. Ship same day as drawn whenever possible; specimens <72 hours old preferred.
