The major subtypes of FTLD-tau are Pick’s disease (PiD), corticobasal degeneration (CBD), progressive supranuclear palsy (PSP), globular glial tauopathy (GGT), frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17), and rare unclassifiable tauopathies. This evidence concerns the gene MAPT and red-green color blindness.
