Biochemical and pathological characterization of frontotemporal dementia due to a Leu266Val mutation in microtubule-associated protein tau in an African American individual.
Frontotemporal dementia (FTD) is a clinically heterogeneous disorder characterized by alterations in language and/or behavior, often in association with Parkinsonism or motor neuron disease. A familial form of FTD is associated with mutations in the microtubule-associated protein tau (MAPT) gene. We report here on the clinical, neuroimaging, cerebral spinal fluid biomarker, genetic, biochemical and postmortem neuropathological analyses of a case of familial FTD with a Leu266Val MAPT mutation which results in a very early age of onset and a rapid course of disease. This is also the first reported case of any MAPT mutation in an individual of African American ethnicity.
