CD79A and infection: We identified significant overlap for 13 genes linked to abnormal IgA levels in mice (enrichment P = 5.8 × 10−5), 29 linked to abnormal immune tolerance (enrichment P = 6.3 × 10−6) and 42 linked to abnormal response to infection (enrichment P = 1.1 × 10−5) (Fig. 3b and Supplementary Tables 6–8).
