Genes associated with other NDs, such as microtubule associated protein tau gene (MAPT), leucine-rich repeat kinase 2 (LRRK2), β-glucocerebrosidase (GBA1), TATA-box binding protein gene (TBP), coiled-coil-helix-coiled-coil-helix domain containing 2 (CHCHD2) and chromosome 9 open reading frame 72 (C9orf72), might be involved in the MSA pathogenesis [63,64,65,66,67,68], but more research is required to determine whether these genes have specific association with MSA pathology. This evidence concerns the gene MAPT and multiple system atrophy.
