Moreover, the results of KEGG analysis demonstrated that the DMBT1 gene was correlated with immune-related diseases, such as asthma, graft versus host disease, the intestinal immune network for IgA production, pertussis, and systemic lupus erythematosus (Figure 6F), and the total ssGSEA enrichment score (Figures 6C, D). Here, DMBT1 is linked to pertussis.
