The molecular mechanisms underlying the co-occurrence of ALS and FTD remain incompletely understood. We report a heterozygous R1101K mutation of the p150 subunit of the molecular motor dynactin (DCTN1) in a family with amyotrophic lateral sclerosis (ALS) and co-occurrence of frontotemporal dementia (FTD). Three members of our kindred were affected with motor neuron disease and two with dementia in an autosomal dominant pattern of inheritance. We excluded the involvement of the ALS and FTD-linked genes for copper/zinc superoxide dismutase (SOD1) and tau. The present study shows that mutations in DCTN1 may result…
