Comparison of the expression status of imprinted genes GNAS, GRB10, SNRPN, IGF2, and IGF2R in the gene screening set. a Heat map showing the expression status of imprinted gene GNAS, GRB10, SNRPN, IGF2, and IGF2R. N, normal samples; B, benign samples; M, malignant samples. Gastric cancers and benign controls are framed with red dashed lines. Additional imprinted genes IGF2 and IGF2R studied are framed with blue dashed lines. b Box plot showing the expression status of imprinted genes in normal, benign, and malignant samples. *p < 0.01
