Despite advances with traditional single genes molecular research, including rare mutations in BRCA1/2 and CDH1 for primary prevention and trastuzumab for treating HER2-overexpressing breast and gastric tumors, overall, treatment failure and death rates are still alarmingly high.
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).
