Most CJD is sporadic; ~15% is familial due to PRNP mutations. The prion protein gene also affects susceptibility to acquired forms.
How Genetic Is Creutzfeldt-Jakob Disease?
Genetics plays a meaningful role in Creutzfeldt-Jakob Disease, with heritability estimated at around 10%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Creutzfeldt-Jakob Disease: PRNP. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
