MAPT and frontotemporal dementia: Outside the HLA region, we found 7 other FTD- and immune-associated SNPs (Fig 2; Table 2), including 2 in strong LD that mapped to the H1 haplotype of microtubule associated protein tau (MAPT) (LD: rs199533 and rs17572851; nearest genes: NSF and MAPT, pairwise D′ = 1, r2 = 0.94).
