| description | Glial Nuclear Antibody (AGNA) Type 1 antibody is a marker found in paraneoplastic syndrome associated with small cell lung carcinoma (SCLC). It is also closely associated with paraneoplastic Lambert-Eaton Myasthenia Syndrome (LEMS). There appears to be a tight association between AGNA and voltage-gated calcium channel antibodies in patients with SCLC. Patients with AGNA have characteristic nuclear staining of the Bergmann glia in the Purkinje cell layer of the cerebellum.

Tavolato, B. Giometto, A. Vincent and Francesc Graus, JNNPm 2007; 78; p. 204-205. | ||
