According to the results of the preliminary analysis, a single RCGY site ineach of the brinp1, bves,cacna2d3, cdh11, cpeb1,epha7, fgf2, galr1,gata4, hopx, hs3st2,irx1, lrrc3b, pcdh10,rprm, runx3, sfrp2,sox17, tcf21 tfpi2, wnt5a,zfp82, and znf331 genes was selected tofurther study the full collection of DNA samples derived from tumor (n = 29)and morphologically unchanged (n = 25) stomach mucosa tissues of GC patients(Table 2). This evidence concerns the gene SOX17 and neoplasm.
