KCNQ5 and gastric cancer: To this end, a study by Ren et al. identified 153 cfDNA methylation biomarkers, including KCNQ5, CABIN1, and DOCK10, for detecting GC using a genome-scale DNA methylation analysis method (MCTA-Seq) on the plasma samples from patients with GC (n = 89) and controls (n = 82), as well as 28 pairs of GC and adjacent non-neoplastic tissues.
