For example, lead SNP rs4795899-A (Supplementary Table S5) with nearest gene CCL11 (Table 1) was associated with protection from Crohn’s disease (p = 7.7 × 10−7) and increased risk of ER-negative breast cancer (p = 5.9 × 10−5) and was correlated with CD4, CD8A, CD11B and CD45 expression in TCGA breast tumors with Spearman’s ρ ranging from 0.34 to 0.49 (Figure 1). The gene discussed is PTPRC; the disease is Crohn disease.
