KCNN4 has been shown to have positive correlations with several costimulatory molecules (CD276, CD40, CD70, CD80, CD86), immune signaling receptors (IL2RA, MICB, NT5E), and multiple TNFRSF family members, suggesting its involvement in immune modulation, inflammation, and tumor‐immune interactions. Here, KCNN4 is linked to neoplasm.
