rs8070723 is an intronic A/G SNP (major allele A frequency 0.881, minor allele G frequency 0.119) in MAPT, the gene that encodes the microtubule-associated protein tau, and is associated with Progressive Supranuclear Palsy (Hoglinger et al., 2011) and with Parkinson’s Disease (UK Parkinson’s Disease Consortium et al., 2011). This evidence concerns the gene MAPT and Parkinson disease.
