Across all lines, 17 GO terms were defined as significantly enriched in SNP dense genes, of these 10 were enriched in more than one line, with the four immune related terms: “Herpes simplex infection” (KEGG: 05168); “Cytokine-cytokine receptor interaction” (KEGG: 04060); “Intestinal immune network for IgA production” (KEGG: 04672); and “Phagosome” (KEGG: 04145), being the most widely represented (significant in 7, 7, 5 and 5 lines respectively). The gene discussed is CD79A; the disease is herpes simplex infectious disease.
