摘要: Previous segregation analyses of pedigrees from areas China where esophageal squamous cell carcinoma (ESCC) rates are extraordinarily high suggested a Mendelian mode transmission. We initiated search for major ESCC gene by conducting genome-wide scan in tumors. Chromosome 13 showed loss heterozygosity (LOH) 95% microsatellite markers, the highest frequency LOH on any chromosome. In current study, we established high-resolution deletion map using 107 markers 13q and compared family history upper gastrointestinal cancer. Overall allelic was significantly higher those with positive (versus negative) history, suggesting presence an inherited tumor suppressor ESCC.
