We conducted a gene correlation analysis and found that MXD3 expression in cancer cohorts was near-perfectly correlated (r ≥ 0.99) with expression levels of several other genes, including DBN1, RAB24, SLC34A1, PRELID1, LMAN2, F12, GRK6, RGS14, PRR7, and PFN3 (Fig. 6C). The gene discussed is GRK6; the disease is cancer.
