Among the other, this group comprise: Contactin-associated protein-like 2 (Caspr2) correlated with memory and affective disturbances (41), Glial fibrillary acidic protein (GFAP) potentially connected with thymoma and other more rare neoplasms (40) and it is postulated that this antibody presented in plasma has a potential in differentating SCA with MSA-C.
