Mutations in PSEN1 are the most common cause of autosomal dominant familial Alzheimer's disease (FAD). We describe an African-American woman with a family history consistent with FAD who began to experience cognitive decline at age 50. Her clinical presentation, MRI, FDG-PET, and PIB-PET scan findings were consistent with AD and she was found to have a novel I238M substitution in PSEN1. As this mutation caused increased production of Aβ42 in an in vitro assay, was not present in two population databases, and is conserved across species, it is likely to be pathogenic for FAD.
