A PrP gene codon 178 base substitution and a 24-bp interstitial deletion in familial Creutzfeldt-Jakob disease.
Several mutations in the prion protein (PrP) gene are associated with familial Creutzfeldt-Jakob disease (FCJD). We describe a family in which five members in three generations have had FCJD. The proband and some descendants of the affected members carried an abnormal PrP gene allele. This allele contained a 24-bp deletion from the tandem repeat region of the open reading frame and a codon 178 missense substitution. Observations suggest that the codon 178 mutation is involved in the pathogenesis of FCJD in the family described here. The 24-bp deletion may be an uncommon polymorphism.
