Families with truncating variants located in the PRE-PRO-region of the CDH1 gene were six times more likely affected by colorectal cancer, variants in the intracellular region were protective for cancer at young age and in the linker regions for breast cancer. These genotype-phenotype associations may aid identification of high-risk groups and individualize risk-reducing intervention strategies pending future validation and creation of risk prediction models.
