Genetics

PRNP Mutations

P102L: Most common mutation
A117V: Second most common
F198S: Associated with 'cotton wool' plaques
Q217R: Scandinavian founder mutation
Octapeptide repeat insertions: Variable phenotype

Penetrance

High penetrance, typically adult onset
Variable age of onset (35-70 years)
Disease duration: 1-10 years

Prion Protein Pathogenesis

Normal PrP (PrP^C)

Cellular function: Copper binding, synaptic plasticity
Localization: Cell membrane, lipid rafts
Structure: Alpha-helix rich, globular domain

Mutant PrP^Sc

Conformational change: β-sheet rich aggregation
Protease resistance: Partial proteinase K resistance
Neurotoxicity: Gain-of-function mechanism
Cell-to-cell spread: Template-directed conversion

Vulnerable Brain Regions

Cerebellum

Purkinje cells: Severe loss
Granule cells: Degeneration
Deep cerebellar nuclei: Involvement
Ataxia correlation: Cerebellar pathology

Cerebral Cortex

Frontal lobe: Neuronal loss
Temporal lobe: Variable involvement
Cortical degeneration: Cognitive decline

Subcortical Structures

Substantia nigra: Variable involvement
Thalamus: Specific nuclei affected
Brainstem: Reticular formation

Neuropathology

PrP Deposits

Amyloid plaques: 'Kuru-type' multicentric plaques
Perivacuolar localization: Spongiform changes
Amyloid angiopathy: Vascular involvement
Synaptic pathology: Presynaptic terminals

Spongiform Change

Vacuolation: Intracellular vacuoles
Astrocytosis: Reactive gliosis
Neuronal loss: Variable by region

Molecular Mechanisms

PrP Aggregation

N-terminal mutations: Altered protein interactions

Glycosylation changes: Altered trafficking

Membrane association: Lipid raft dysfunction

ER stress: Unfolded protein response

Neurodegeneration

Oxidative stress: ROS accumulation
Calcium dysregulation: Excitotoxicity
Synaptic failure: Neurotransmitter deficits
Autophagy impairment: Aggregate clearance

Clinical Features

Core Symptoms

Progressive cerebellar ataxia
Cognitive decline/dementia
Pyramidal signs
Pseudobulbar affect

Disease Progression

Initial: Gait instability
Mid: Limb ataxia, dysarthria
Late: Severe dementia, immobility

Research Models

Cellular

iPSC-derived neurons: Patient neurons with PRNP mutations
PrP-transfected cells: Overexpression systems
Organoids: Cerebral organoid models

Animal

Transgenic mice: P101L, F198S models
Knock-in models: Patient mutations
PrP-null mice: Background strain

Diagnostic Biomarkers

14-3-3 protein: In CSF (supportive)
Tau protein: Elevated in CSF
PrP^Sc detection: RT-QuIC, PMCA
MRI: Cerebellar/cortical atrophy
