© 1984 American Academy of Neurology Familial amyloid polyneuropathyA new kinship of German ancestryFrom the Arthritis and Connective Tissue Disease Section, the Thorndike Memorial Laboratory and Division of Medicine, Boston City Hospital, Boston University School of Medicine, Boston, MA. Familial amyloid polyneuropathy (FAP) is an autosoma1 dominant inherited disorder that primarily affects the peripheral and autonomic nervous systems and usually becomes symptomatic in the third or fourth decade. Because of the confusion with other genetically transmitted neurologic conditions, the diagnosis is often delayed until advanced stages. We describe a new German kinship with FAP in which the disorder was detected in two asymptomatic family members who were seeking genetic counseling.
