Mutation-specific histopathological variations across the spectrum of gCJD phenotypes. a Modified, “thickened” synaptic pattern of PrP deposition in the molecular layer of cerebellum in a patient carrying the E200K-129M haplotype. b, c Granular PrP deposits with long-thin (b) and short-thick (c) stripe-like appearance distributed perpendicularly to the surface in the molecular layer of cerebellum in 6- and 4-OPRI-129M carriers, respectively. d Round patches of fine, granular PrP deposits in the deep frontal cortex of a 4-OPRI-129M case. e Multiple, small PrP-amyloid plaques in the cerebellar molecular layer in a E211Q-129M carrier. f, g Multiple, intraneuronal globular PrP deposits distributed in the perikaryon in a E200K-129V individual with PrPSc type 2 (f, deep layers of frontal cortex) and E200K-129M with PrPSc type “i” (g, pons). h–k Spongiform change characterized by small and intermediate, non-confluent vacuoles in the caudate nucleus, and granular/mini plaque-like PrP deposits in the striatum and molecular layer of cerebellum of patients with T183A-129M (h, i) and atypical 6-OPRI-129V (j, k), respectively. Immunohistochemistry for PrP with mAb 3F4 (a–g, i, k), and haematoxylin–eosin staining (h, j)
