IMMUNOLOGY

Detailed explanation-1: -A prion is composed of an abnormally folded protein that causes progressive neurodegenerative conditions, with two of the most notable being Bovine spongiform encephalopathy (BSE or mad cow disease) seen in cattle and livestock and Creutzfeldt-Jakob disease (CJD) seen in humans.

Detailed explanation-2: -Genetic prion disease follows an autosomal dominant inheritance pattern, which means that if you carry a prion-disease-causing mutation, each of your children has a 50 percent (1 in 2) chance to inherit the same mutation.
