Paraneoplastic cerebellar degeneration (PCD).
Hodgkin disease, rarely, non-Hodgkin lymphoma.
Frequency of anti-Tr antibodies in patients with suspected PCD without evidence of cancer: 11% (3/28)
Frequency of anti-Tr antibodies in patients with Hodgkin disease alone:
0% (30 cases studies)
Immunohistochemistry on frozen rat or mouse cerebellar sections. (figure).

Not available. Antibody not detected by immunoblot
Patients with anti-Tr antibodies frequently have anti-MAZ (myc-associated zinc-finger protein) antibodies. In one study 16 of 19 patients presented both antibodies. However, anti-MAZ antibodies were also present in 16 of 131 controls.
