NCIt definition : Human TFF1 wild-type allele is located in the vicinity of 21q23.1 and is approximately
4 kb in length. This allele, which encodes trefoil factor 1 protein, is involved in
gastrointestinal mucosa stabilization. Wild type allele dysfunction, including altered
expression, deletion, and/or mutation, is observed frequently in human gastric carcinomas.;
