Neither the protective nor the disease-susceptible HLA-B alleles were significantly enriched in any of these groupings (Fig 1G), apart from HLA-B*57 when comparing PP with PSP and PSP-VC (p = 0.05 and p = 0.03, respectively; S3A and S3B Fig). The gene discussed is HLA-B; the disease is supranuclear palsy, progressive, 1.
