Finally, two variants at the MAPT (tau) locus were associated with both ADRD and PD: the PD lead variant rs62053943 (chr17:45,666,837), and rs199526 (chr17:46,770,341), a linkage disequilibrium (LD) proxy of the ADRD lead variant rs199515 (chr17:46,779,275) with r2= 0.911 in TopLD. The gene discussed is MAPT; the disease is Parkinson disease.
