The blepharocheilodontic syndrome is a rare autosomal dominant disorder characterized by lower eyelid ectropion, upper eyelid distichiasis, euryblepharon, bilateral cleft lip and palate, and conical teeth. An additional rare manifestation is imperforate anus (summary by Weaver et al., 2010). [from OMIM]

Hereditary diffuse gastric cancer (HDGC) is an autosomal dominant susceptibility for diffuse gastric cancer, a poorly differentiated adenocarcinoma that infiltrates into the stomach wall causing thickening of the wall (linitis plastica) without forming a distinct mass. Diffuse gastric cancer is also referred to as signet ring carcinoma or isolated cell-type carcinoma. The average age of onset of HDGC is 38 years (range: 14-69 years). The majority of the cancers in individuals with a CDH1 pathogenic variant occur before age 40 years. The estimated cumulative risk of gastric cancer by age 80 years is 70% for men and 56% for women. Women are also at a 42% risk for lobular breast cancer. [from GeneReviews]

Ovarian cancer, the leading cause of death from gynecologic malignancy, is characterized by advanced presentation with loco-regional dissemination in the peritoneal cavity and the rare incidence of visceral metastases (Chi et al., 2001). These typical features relate to the biology of the disease, which is a principal determinant of outcome (Auersperg et al., 2001). Epithelial ovarian cancer is the most common form and encompasses 5 major histologic subtypes: papillary serous, endometrioid, mucinous, clear cell, and transitional cell. Epithelial ovarian cancer arises as a result of genetic alterations sustained by the ovarian surface epithelium (Stany et al., 2008; Soslow, 2008). [from OMIM]

BRCA1- and BRCA2-associated hereditary breast and ovarian cancer (HBOC) is characterized by an increased risk for female and male breast cancer, ovarian cancer (including fallopian tube and primary peritoneal cancers), and to a lesser extent other cancers such as prostate cancer, pancreatic cancer, and melanoma primarily in individuals with a BRCA2 pathogenic variant. The risk of developing an associated cancer varies depending on whether HBOC is caused by a BRCA1 or BRCA2 pathogenic variant. [from GeneReviews]
