Genetic studies of Chinese FTD populations have revealed genotype-phenotype correlations: MAPT mutations with frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17), GRN mutations with frontotemporal lobar degeneration with TDP-43 proteinopathy (FTLD-TDP), C9orf72/CHCHD10/TBK1 mutations with amyotrophic lateral sclerosis (ALS)-FTD spectrum disorders, and VCP mutations with inclusion body myopathy associated with Paget disease of bone and frontotemporal dementia (IBMPFD) (Jiang et al., 2021). This evidence concerns the gene VCP and amyotrophic lateral sclerosis.
