Genetics

FAD3 results from mutations in the PS-1 gene that increase production of A4/42.[2] These mutations selectively increase the formation of A4/42 relative to A4/40.

Clinical manifestations

FAD3 is the most aggressive, earliest symptomatic form of familial Alzheimer's disease (FAD), commonly leading to onset of symptoms before age 50 & demise of the patient in their 60s.
