For example, gastric cancer patients carrying ABCA13 mutant in C2 group is found to have an upregulated expression of LINC2826, AC25575.2, and AFAP-AS1 than the wild type (Supplementary Fig. 2), but no difference of AC25575.2 and AFAP-AS1 expression is observed in the C1 group, suggesting that ABCA13 is epigenetically regulated by these lncRNAs which collectively affects the survival of gastric cancer. This evidence concerns the gene ABCA13 and gastric cancer.
