Correlation between GNG7 expression and clinical features in LUAD. (A) GNG7 expression is significantly lower in tumor tissues compared to normal tissues (P<0.0001). (B) No significant difference in GNG7 expression between gene mutation and wild-type groups. (C) GNG7 expression is reduced in samples with copy number deletions compared to diploid samples (P<0.001). (D) Lower GNG7 expression is observed in advanced cancer stages (III–IV) compared to early stages (I–II) (P<0.01). (E) Kaplan–Meier survival curves show that low GNG7 expression is associated with poorer overall survival (P<0.0001).
