HLA-DRB5 and Parkinson disease: By comparing the associated eQTL signals across tissues we found that PD risk alleles at this locus are associated with increased expression of 7 HLA-genes (HLA-B, HLA-C, HLA-DQA1, HLA-DQB1, HLA-DQB1-AS1, HLA-DRB1, HLA-DRB5) and decreased expression of 4 genes (HLA-DOB, HLA-DQA2, HLA-DQB2, HLA-DRB6).
