Molecular assay reagents intended to identify mutations in the presenilin 1 (PSEN1) gene, located at chromosome 14q24.3, which encodes for the protein presenilin 1 that helps process certain proteins important for transmitting biochemical signals from the cell membrane into the nucleus of the cell. Genetic mutations are associated with early-onset familial Alzheimer\'s disease type 3.
