Mutations in three genes [chromosome 9 open-reading-frame 72 (C9ORF72); microtubule-associated protein tau (MAPT) and progranulin (GRN)] account for the vast majority of familial, and a proportion of sporadic, frontotemporal dementia (FTD) cases. Progressive apraxia of speech (PAOS) is a type of FTD characterized by speech production deficits without a known cause.
