PLP1 and nervous system disorder: Among all Diseases and Biofunction predicted, we focused our attention on Neurological Diseases, where we found a significant association among several proteins up-regulated in SAL, such as Myelin oligodendrocyte glycoprotein (MOG), Myelin proteolipid protein (PLP1), Sodium/potassium-transporting ATPase subunit beta-2 (ATP1B2), Neurofilament medium polypeptide (NEFM) and movement disorders, neurodegeneration and paralysis (Table 1).
