Recent studies have highlighted the aberrant expression of the CAPG gene in various cancers, including gastric cancer [10], triple‐negative breast cancer [11], colorectal cancer [12], Acute myeloid leukemia [13], nasopharyngeal carcinoma [14], glioblastoma [15] and bladder cancer [16], etc. implicating its role in tumour invasion and metastasis. The gene discussed is CAPG; the disease is cancer.
