Figure 3. Frequencies of major FTD phenotypes according to the genotype in TARDBP, GRN, C9orf72, and MAPT carriers.

Figure 3

The frequency of svFTD phenotype was higher in TARDBP carriers compared with GRN, C9orf72, and MAPT carriers (p < 0.001). The frequency of nfvFTD was not different in TARDBP carriers compared with others groups, but was higher in GRN carriers compared with C9orf72 carriers (p < 0.001). The frequencies of bvFTD and corticobasal syndrome (CBS) phenotypes were similar in the 4 groups. FTD = frontotemporal dementia; nfvFTD = nonfluent variant of frontotemporal dementia; svFTD = semantic variant of frontotemporal dementia.
