Codon 178 mutation of the human prion protein gene in a German family (Backer family): sequencing data from 72-year-old celloidin-embedded brain tissue

Abstract

Familial Creutzfeldt-Jakob disease was first described in a family from northern Germany in the 1920s (Backer family). PCR amplification of DNA extracted from brain tissue embedded in celloidin 72 years ago shows a GAC to AAC substitution at codon 178 of the prion protein gene. This mutation is associated with fatal familial insomnia and familial Creutzfeldt-Jakob disease in a number of families of diverse ethnic background.
