Genes responsible for early onset Alzheimer’s disease, including chromosomal location and function.
| Gene name (symbol) | Chromosomal location | Function of encoded protein |
| Amyloid precursor protein (APP) | 21q21.3 | Implicated in neuronal development and synaptic formation and repair | Presenilin one (PSEN1) | 14q24.2 | Cleavage of the amyloid precursor protein and NOTCH receptor proteins via overlapping, but distinct mechanisms [12, 13] | Presenilin two (PSEN2) | 1q42.13 |
