MAPT and Parkinson disease: Although Compta et al. compared the levels of t‐tau and p‐tau181 in PD patients with different MAPT rs1880753, rs1880756, rs1800547, rs1467067, rs242557, rs2471738, and rs7521 genotypes, they found no significant differences in t‐tau and p‐tau181 levels in contrast to the present study that reveals t‐tau and p‐tau levels to be altered in patients with different MAPT rs1467967 and rs2471738 genotypes.
