CDH1 (Cadherin-1) variants and mutations

CDH1 (also known as Cadherin-1) is a human protein-coding gene encoding a cadherin-1 protein. Its E-cadherin-mediated adhesion preserves epithelial architecture and suppresses inappropriate cell detachment and invasion. Germline loss-of-function variants cause hereditary diffuse gastric cancer syndrome and substantially increase diffuse gastric and lobular breast-cancer risk. This analysis covers 4,399 CDH1 variants and mutations. Of these, 33% have computational variant effect predictions. Disease context includes developmental and epileptic encephalopathy 109, neurodegenerative disease, and undetermined early-onset epileptic encephalopathy. Example CDH1 variants include M1I, M1K, and M1L.
