Abstract
Fatal familial insomnia (FFI), a condition characterized by inability to sleep, dysautonomia, motor disturbances, and selective thalamic atrophy is a prion disease linked to a GAC----AAC mutation at codon 178 of the prion gene. These data were obtained from one kindred. We now report a second kindred affected by FFI and carrying the same mutation. The finding of the same disease phenotype and genotype in a second family further validates FFI as a distinct disease entity and a phenotype of the GAC----AAC mutation at codon 178 of the prion gene.Keywords
