This variant is denoted CDH1 c.1697T>C at the cDNA level, p.Ile566Thr (I566T) at the protein level, and results in the change of an Isoleucine to a Threonine (ATA>ACA). This variant has been reported in an individual with triple negative breast cancer (Lovejoy 2018). CDH1 Ile566Thr was not observed at a significant allele frequency in large population cohorts (Lek 2016). This variant is located in Extracellular (Cadherin 4) domain (Brooks-Wilson 2004, Figuereido 2013). In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect. Based on currently available evidence, it is unclear whether CDH1 Ile566Thr is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.
