Further bioinformatics analysis of the ASCL2 in STAD patients using the cBioPortal and GEPIA system shows that the ASCL2 may be related to CNTNAP3, CLIP1, C9orf84, ARIH2, and IL1R2 mutations and involved in stomach carcinoma prognosis, which requires further verification in future studies. Here, ARIH2 is linked to gastric carcinoma.
