TP63 FISH Probe
The TP63 FISH probe is designed to hybridize to the TP63 gene and is primarily used for detecting amplifications and deletions associated with the gene. This probe
is FISH confirmed on normal peripheral blood metaphase spreads and interphase nuclei. The probe can be labeled in one of five colors. Each probe is sold in a 20 test kit (approximately 20 slides - 22x22 mm area) and includes
hybridization buffer. Please note that due to design optimizations, prices are subject to change.

This gene encodes a member of the p53 family of transcription factors. The functional domains of p53 family proteins include an N-terminal transactivation domain, a central DNA-binding domain and an oligomerization domain. Alternative splicing of this gene and the use of alternative promoters results in multiple transcript variants encoding different isoforms that vary in their functional properties. These isoforms function during skin development and maintenance, adult stem/progenitor cell regulation, heart development and premature aging. Some isoforms have been found to protect the germline by eliminating oocytes or testicular germ cells that have suffered DNA damage. Mutations in this gene are associated with ectodermal dysplasia, and cleft lip/palate syndrome 3 (EEC3); split-hand/foot malformation 4 (SHFM4); ankyloblepharon-ectodermal defects-cleft lip/palate; ADULT syndrome (acro-dermato-ungual-lacrimal-tooth); limb-mammary syndrome; Rap-Hodgkin syndrome (RHS); and orofacial cleft 8.

Anaplastic large cell lymphoma (ALCL) is a rare form of T-cell lymphoma that makes up about 3% of adult non-Hodgkin lymphoma. Recently, TP63 translocations have emerged as a new class of biomarkers in ALCL. This study examined two cases of TP63-rearranged ALCL, using Empire Genomics’ TP63 break apart probe to detect translocations of the gene. Although the effects of TP63 rearrangement still aren’t clear, results suggest that the N-terminal domain of the protein, which is truncated as a result of gene rearrangement, may act as a tumor suppressor.
Systemic, primary cutaneous, and breast implant-associated ALK-negative anaplastic large cell lymphomas, although diverse in their clinical features, can be difficult to distinguish histopathologically. This study sought to cytogenetically discern between these lymphoma 3 subtypes using IHC and FISH. Twenty-two S-ALCL ALK?, 13 PC-ALCL, and 2 BI-ALCL were analyzed. Empire Genomics' PD-L1 and TP63 break apart probes were used to detect PD-L1 and TP63 rearrangements.
This publication looked at 4 different ALCL subtypes to determine whether a correlation existed between several tumor microenvironment factors (PDL1 expression, FOXP3+ regulatory cell density, and CD8+ tumor-infiltrating lymphocyte density) and ALCL subtype. Our break apart probes for DUSP22/IRF4 and TP63 were used to determine which patients fell into 2 of the 4 ALCL subtypes under analysis: DUSP22/IRF-rearranged ALCL and TP63-rearranged-ALCL.
