Question

Quizplus · Accepted Answer

Protection against inherited prion disorders seems to depend upon whether people are heterozygotes at a particular part of the prion protein gene, which is known as codon 129. People who are heterozygous at codon 129 (having one normal allele and one variant allele) may have a milder form of the disease or may not develop it at all, whereas those who are homozygous for the normal or variant allele may be at greater risk.
