Schizophrenia has been linked to a region on chromosome 17q21 in Latino populations (Escamilla et al., 2009). Mutations of a gene at this location (GRN) are associated with frontotemporal dementia. A recent study demonstrated that patients with frontotemporal dementia who presented with symptoms of schizophrenia show neuropathological findings consistent with GRN mutations, but were not tested for GRN mutations (Velakoulis, Walterfang, Mocellin, Pantelis, & McLean, 2009). The current study describes a Latino family in which two siblings have schizophrenia and one has frontotemporal dementia. We sequenced GRN in one of the siblings with frontotemporal dementia and one of the siblings with schizophrenia. The siblings both have a loss-of-function GRN mutation. This finding, in conjunction with other studies (Escamilla et al., 2009; Velakoulis et al., 2009), suggests that there may be an association between schizophrenia, frontotemporal dementia, and GRN mutations in Latino populations that should be investigated further.
