    AbstractProgranulin is a multifunctional growth factor mainly expressed in neurons and microglia. Loss-of-function mutations in the Granulin (GRN) gene are causative of frontotemporal dementia with TAR DNA-binding protein-43 inclusions. We reported the case of a 51-year-old male patient affected by sporadic agrammatic variant of primary progressive aphasia, in whom we identified a novel heterozygous deletion in the exon 6 (g.10338_39delAG, p.Arg161GlyfsX36). Plasma progranulin levels were significantly reduced and in silico analysis predicted a premature termination codon. This case expands our knowledge on GRN mutations in frontotemporal dementia.
