A Novel Presenilin-1 Mutation (Leu85Pro) in Early-Onset Alzheimer Disease With Spastic Paraparesis

Abstract excerpt

BACKGROUND: Early-onset familial Alzheimer disease is caused by mutations in the amyloid precursor protein (APP), presenilin-1 (PSEN1), or presenilin-2 (PSEN2) genes. Phenotypic diversity has been reported to be associated with various mutations in PSEN1. Various mutations of PSEN1 have been reported in cases of early-onset Alzheimer disease with spastic paraparesis. OBJECTIVE: To describe a novel mutation in the...
