Two Variants in the NOTCH4 and HLA-C Genes Contribute to Familial Clustering of Psoriasis

Figure 1

A Manhattan plot of the stepwise conditional association for psoriasis with a family history (PFH) in the major histocompatibility complex (MHC) region. Stepwise analysis of HLA-C, NOTCH4, HLA-B, HLA-DPB1, and TAP2 in PFH vs. control. For each plot, the horizontal axis shows the genomic position, and the vertical axis shows negative log10-transformed values for association. The dashed horizontal line corresponds to the significance threshold of . The red triangles represent the top associated variants.
