Single nucleotide polymorphisms (SNPs) across a chromosomal region expanding 1.3 Mb of the MAPT H1 haplotype have shown association with the risk for developing Parkinson’s disease (PD) [3]–[8], progressive supranuclear palsy [3], [9], [10], corticobasal degeneration [3], and multiple system atrophy [11]. This evidence concerns the gene MAPT and progressive supranuclear palsy.
