Subsequently, 148 patients with GI cancers (including esophageal and gastric cancers) and 283 cancer\u2010free patients were recruited. The frequency of the suspected mutations in both groups was determined using Sanger sequencing. Furthermore, immunofluorescence (IF) assays for XAF1 protein expression were performed in paraffin\u2010embedded surgically resected tumor tissues from patients with GI cancer, with or without the mutation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In a family with GI cancer, we identified a mutation of\n                      <jats:italic>XAF1<\/jats:italic>\n                      (c.454+1372G&gt;A), which is a nonsense mutation in Exon 4b that results in a truncated XAF1 Isoform 5. Sanger sequencing of sporadic cancer patients and cancer\u2010free populations further verified that the frequency of this mutation was enriched in patients with GI cancer.
