RAB28 and gastric adenocarcinoma: Other MS loci display marked cancer-type specificity, for example, MSI events within the 5′ UTR region of ZNF738, C10orf140, ZNF271 and RAB28 are specific to COAD tumours, whereas those in EBP, TMEM182, MIR567 and MEIS1 are absent or substantially depleted in STAD compared to COAD and UCEC tumours.
