The majority was diagnosed with FTD (74.4%), with a relative higher frequency of the language variant in comparison to C9orf72 carriers. Psychiatric features were less frequently reported in GRN carriers than in C9orf72 and TBK1 carriers. Neuroimaging showed considerable vascular white matter changes more often in GRN carriers than in C9orf72 carriers. The neuropathology was compatible with FTLD-TDP type A with a significant occurrence of atherosclerotic small vessel changes. Carriers of the genetic GRN rs5848 variant, developed disease on average 3.5 years earlier.Conclusions: The clinical and neuropathological phenotype of the GRN founder mutation is comparable to previous descriptions for GRN mutation carriers. Our data confirmed the GRN rs5848 variant as an onset age genetic modifier in the Belgian founder family.Disclosure: Dr. Van Mossevelde has nothing to disclose. Dr. Wauters has nothing to disclose.
