FTD-related studies demonstrated distinct patterns of neurodegeneration based on genetic mutations (C9orf72, MAPT, GRN), suggesting that genotype-specific atrophy patterns could inform early diagnostic biomarkers.(Sellami, et al. 2018) (Cash et al. 2018) (Shinagawa et al. 2015) (Lee et al. 2014). This evidence concerns the gene C9orf72 and frontotemporal dementia.
