For example, APOE4 is a gene variant that increases amyloid, but you can inherit a copy of APOE4 from mom and dad and still never get Alzheimer's, which means that for most of us, our DNA alone does not determine whether we get Alzheimer's.
Per exemple, l'ApoE4 és un gen variant que augmenta els amiloides, però es pot heretar una còpia del ApoE4 de la mare i el pare i no desenvolupar mai Alzheimer, que significa que, per a la majoria, el nostre ADN sol no determina si tindrem la malaltia.
