Type I anti-neuronal nuclear antibody (ANNA-1) is present in patients with paraneoplastic syndromes (paraneoplastic sensory neuropathy or paraneoplastic encephalomyelitis) most commonly associated with small-cell lung carcinoma (SCLC). ANNA-2 is present in patients with midbrain encephalitis, cerebellar ataxia, eye movement disorders (usually opsoclonus), and occasionally myelopathy. Neoplasms most often associated with ANNA-2 are breast carcinoma and SCLC. ANNA-1 and ANNA-2 may be detectable before the associated neoplasm is detectable. Source: ARUP Laboratories, ANNA
