[[http://www.uniprot.org/uniprot/CADH1_HUMAN CADH1_HUMAN]] Defects in CDH1 are the cause of hereditary diffuse gastric cancer (HDGC) [MIM:[http://omim.org/entry/137215 137215]]. An autosomal dominant cancer predisposition syndrome with increased susceptibility to diffuse gastric cancer. Diffuse gastric cancer is a malignant disease characterized by poorly differentiated infiltrating lesions resulting in thickening of the stomach. Malignant tumors start in the stomach, can spread to the esophagus or the small intestine, and can extend through the stomach wall to nearby lymph nodes and organs. It also can metastasize to other parts of the body. Note=Heterozygous germline mutations CDH1 are responsible for familial cases of diffuse gastric cancer. Somatic mutations in the has also been found in patients with sporadic diffuse gastric cancer and lobular breast cancer.<ref>PMID:10319582</ref><ref>PMID:12216071</ref> Defects in CDH1 are a cause of susceptibility to endometrial cancer (ENDMC) [MIM:[http://omim.org/entry/608089 608089]]. Defects in CDH1 are a cause of susceptibility to ovarian cancer (OC) [MIM:[http://omim.org/entry/167000 167000]]. Ovarian cancer common malignancy originating from ovarian tissue. Although many histologic types of ovarian neoplasms have been described, epithelial ovarian carcinoma is the most common form. Ovarian cancers are often asymptomatic and the recognized signs and symptoms, even of late-stage disease, are vague. Consequently, most patients are diagnosed with advanced disease. | |||
==Function== | |||
[[http://www.uniprot.org/uniprot/CADH1_HUMAN CADH1_HUMAN]] Cadherins are calcium-dependent cell adhesion proteins. They preferentially interact with themselves in a homophilic manner in connecting cells; cadherins may thus contribute to the sorting of heterogeneous cell types. CDH1 is involved in mechanisms regulating cell-cell adhesions, mobility and proliferation of epithelial cells. Has a potent invasive suppressor role. It is a ligand for integrin alpha-E/beta-7.<ref>PMID:16417575</ref> E-Cad/CTF2 promotes non-amyloidogenic degradation of Abeta precursors. Has a strong inhibitory effect on APP C99 and C83 production.<ref>PMID:16417575</ref> [[http://www.uniprot.org/uniprot/KLRG1_HUMAN KLRG1_HUMAN]] Plays an inhibitory role on natural killer (NK) cells and T-cell functions upon binding to their non-MHC ligands. May mediate missing self recognition by binding to a highly conserved site on classical cadherins, enabling it to monitor expression of E-cadherin/CDH1, N-cadherin/CDH2 and R-cadherin/CDH4 on target cells.<ref>PMID:19604491</ref> | |||
