This multicenter study evaluated the association of 9 single nucleotide polymorphisms (SNP) in AXIN2 and CDH1, representing genes consistently altered in breast and gastric tumors, with NSCL ± P in 223 trios (father, mother and patient with NSCL ± P) by transmission disequilibrium test (TDT). This evidence concerns the gene AXIN2 and gastric neoplasm.
