Part Description

LP230270-3   Contactin-associated protein 2
Contactin-associated protein 2 (CASPR2) is present in the axons of the granule neurons of the cerebellum and the juxtaparanodal region of myelinated axons. Increased titers of CASPR2 antibodies were first discovered in patients with Morvan's syndrome. Symptoms of Morvan's syndrome include neuromyotonia, insomnia, autonomic dysfunction and neuropathic pain. Though CASPR2 antibodies have been found in 10% of patients with idiopathic cerebellar ataxia, no specific disease has been attributed to patients with the rare occurrence of positive antibodies for CASPR2 with cerebellar involvement.
