GenAge entry for PSEN1 (Homo sapiens)

Gene name (HAGRID: 224)

HGNC symbol: PSEN1
Aliases: FAD; S182; PS1; AD3
Common name: presenilin 1

Potential relevance to the human ageing process

Main reason for selection: Entry selected based on indirect or inconclusive evidence linking the gene product to ageing in humans or in one or more model systems
Description: The PSEN1 gene has multiple transcriptional variants and its functions could include the cleavage of APP and notch receptor protein. PSEN1-null mice die shortly after birth [1368]. Inactivating PSEN1 in the postnatal forebrain reduced beta-amyloid generation with subtle cognitive deficits [1374]. Mutations in the human PSEN1 gene cause early-onset Alzheimer's disease [1381], though PSEN1's role in human ageing remains largely unknown.
