<h3>What leads to prion disease? </h3>
A misfolded confirmation of proteins is called Prions. These misfolded proteins can result in harmful functional proteins and cause several diseases.
A prion is the type of protein that usually cause the normal proteins in the brain to fold in an abnormal manner. This results in misfolding of proteins in the brain.
