Question

Protection against inherited prion disorders depends on whether people are heterozygotes at particular part of the prion protein gene. Inherited prion disorders occur due to mutations in the PRNP gene that encodes for the prion protein. Studies have shown that individuals who are heterozygous (have different versions) at a specific location in the PRNP gene have a reduced risk of developing inherited prion disorders compared to homozygous individuals (who have the same version at that location). Therefore, being heterozygous at this location may provide some protection against these disorders. Having extra copies of the prion protein gene or being exposed to contaminated food does not necessarily provide protection against inherited prion disorders.
