Expression of FAP-1 (Fas-associated phosphatase) and resistance to Fas-mediated apoptosis in T cell lines derived from human T cell leukemia virus type 1-associated myelopathy/tropical spastic paraparesis patients.
However, unlike FAP 1, in which peripheral neuropathy is a dominant feature, our patient's clinical manifestations, which included communicating hydrocephalus and myelopathy, were more suggestive of familial oculoleptomeningeal amyloidosis (FOLMA).
