Plots of Stepwise Conditional Association of the HLA Amino Acid Polymorphisms and Classical HLA Alleles
(A–D) Stepwise analysis of HLA-C, HLA-B, HLA-A, and HLA-DQA1 in PsV-affected versus control individuals.
(E) Stepwise analysis of HLA-B in PsA-affected versus PsC-affected individuals. Each diamond represents the –log10(pomnibus) of the amino acid polymorphism encoded by the HLA gene. The colored horizontal line represents the –log10(pomnibus) of the most strongly associated classical allele of the HLA gene. The dotted horizontal line represents the significance threshold of p = 5.0 × 10−8. The most strongly associated amino acid polymorphisms and HLA classical alleles are labeled when their associations satisfied p < 5.0 × 10−8.
