Average brain weight was 1166.7 grams (1000-1260 grams). All brains demonstrated lobar atrophy of frontotemporal distribution. Three patients had a positive family history of dementia; the novel p.K317N mutation was identified in one of them. All patients were homozygous for the H1 MAPT haplotype. Recombinant K317N tau showed a reduced ability to promote microtubule polymerization by turbidity but no significant effect on the kinetics of tau filament aggregation when assessed using electron microscopy. CONCLUSIONS: While often sporadic, GGT can be caused by the novel MAPT p.K317N mutation. Sequencing of MAPT should be considered in patients with GGT and a positive family history of frontal lobe symptoms, motor neuron disease and/or extrapyramidal features. In patients who did not have MAPT mutations, other genetic factors may play a role in the pathogenesis of GGT.
