Sporadic CJD occurs in a random distribution all over the world, and has no known genetic or environmental cause. It apparently arises from a one-in-a-million spontaneous conversion of a normal cellular protein (encoded by a gene on chromosome 20) into an abnormal 3-dimensional shape, or configuration.

"People who develop CJD from eating mad cow contaminated beef have been thought to develop a specific form of the disorder called variant CJD. But new research, released last December, indicates the mad cow pathogen can cause both sporadic CJD and the variant form, vCJD."

Whereas the majority of cases of CJD (about 85%) occur as sporadic disease, a smaller proportion of patients (5-15%) develop CJD because of inherited mutations of the prion protein gene. These inherited forms include Gerstmann-Straussler-Scheinker syndrome and fatal familial insomnia...

Vulnerability to this change can also be inherited, and it may occur for no known reason, as in sporadic CJD. Research has shown no firm link between the occurrence of CJD and any other risk factor, such as sex, occupation or diet.
