In top-25 SLC27A4 co-expression genes in breast cancer tissues, six genes including Solute carrier family 26 member 11 (SLC26A11), calcium activated nucleotidase 1 (CANT1), leucine rich repeat and sterile alpha motif containing 1 (LRSAM1), tubulin folding cofactor D (TBCD), LLGL2 scribble cell polarity complex component (LLGL2), and GDP dissociation inhibitor 1 (GDI1) were associated with poor DMFS (Figure 7c–h). This evidence concerns the gene LLGL2 and breast cancer.
