Sandy's Story: A Life Touched By Genetics
Sandy Tolman (left) has cowden syndrome, an inherited condition that causesbenign and malignant tumors of the skin, mouth, breasts and intestines.
http://www.sjsworld.org/staff/sandystory.htm

Extractions: I hadn't spoken with Dale, my genetic counselor at Southern Maine Genetics Services (SMGS) in Scarborough, in about seven years, and I suddenly had the impulse to call her. Not only did she remember me, but she also remembered "Cowden's Syndrome" (the rare genetic disease I have). I can't tell you how good that made me feel. Southern Maine Genetics Services (at the Foundation for Blood Research) had been recommended to me by my dermatologist. Sandy Tolman (left) has Cowden Syndrome, an inherited condition that causes benign and malignant tumors of the skin, mouth, breasts and intestines. I had been living with the diagnosis of "Accro-keratosis veruciformis of Hopf" for about ten years. However, when growths began to appear internally, the diagnosis was changed to Cowden's syndrome. . Cowden's syndrome was something new to me, and the only information I had about it was from an awful-looking picture in a big green book. So, when I first walked into Dale's office I was scared, confused and sure that, in time I would look like the picture in the big green book.

Extractions: Cowden syndrome : In the comments section (clinical criteria), it is correctly stated that follicular thyroid cancer is the predominant type of thyroid cancer associated with Cowden syndrome, although the papillary type has been reported as well. However, the displayed tumor spectrum incorrectly only lists the papillary type and searching for follicular thyroid cancer will not find Cowden syndrome.

Extractions: D r. Fernandez research focuses on the genetic basis of the neurologic manifestations of a model inherited cancer syndrome, Cowden syndrome. We do know that approximately 25% of individuals with Cowden syndrome seem to have learning disabilities. In addition, approximately 70% of individuals with Bannayan-Ruvalcaba-Riley syndrome (BRRS, an allelic disorder to Cowden syndrome) have some degree of learning difficulty. In individuals who meet the diagnostic criteria for Cowden syndrome, about 70-80% have a detectable mutation in the PTEN gene; approximately 50-60% of individuals with BRRS have an identifiable PTEN mutation. PTEN encodes a dual specificity phosphatase on 10q23.3 and it is known that PTEN is highly expressed during the embryonic period in the central nervous system and the peripheral nervous system. These investigations will allow a better understanding of the relationship between the clinical manifestations and the molecular genetic diagnosis, which will translate in the future in possible interventions and therapies for these neurologic manifestation in Cowden and in other cancer syndromes. Recent efforts have focused on studying the effects of PTEN mutations at the RNA level.
Genetics Of The Gynecologic Cancers
The two hereditary cancer syndromes known to cause endometrial cancers areHereditary Nonpolyposis Colorectal Cancer syndrome and cowden syndrome.
http://www.cancergenetics.med.ohio-state.edu/ccg/gengyncancers.html

Extractions: Genetics of the Gynecologic Cancers Although all cancer is genetic (caused by errors in our genes that lead to uncontrolled cell growth), very few cancers are hereditary (due to a single gene that is running in the family). It is estimated that 5-10% of all cancers are hereditary. So it is important to try to determine which cancers are more likely to be inherited. Some general characteristics of hereditary cancers are: For more information about specific hereditary cancer syndromes, the following list provides a brief review of the syndromes associated with each of the gynecologic cancers.

http://www.au-kbc.org/research_areas/bio/projects/bcinfo/gen/synd.html

Extractions: The incidence of syndrome associated with breast cancer is very low (less than 1%). The various syndromes associated with breast cancer are: A large number of sporadic cancers are due to mutation in p53 but when this occurs in germline cells, it results in Li-Fraumeni syndrome. It is characterized by premenopausal breast cancer in combination with childhood soft tissue tumours, brain tumors, leukemia, lymphoma, and adrenocortical carcinoma. The probability that these individuals will develop breast cancer is 60% overall. Germline mutations are mostly seen in the exon 7 of p53 gene. [OMIM] A detailed account of p53 is discussed here It is an autosomal dominant syndrome characterized by hamartomatous lesions in the breast, GI tract (polyps), CNS (Central Nervous System), skin and mucosa, eyes, thyroid, genitourinary tract and bones. Germline mutations in the PTEN gene is responsible for this syndrome. Diagnosis is established through identification of characteristic skin lesions (acral keratosis, facial trichilemmomas, and oral papules). It is also called as multiple hamartoma syndrome. PTEN is a tumour suppressor gene located on 10q23 chromosome. The gene product of PTEN is a phosphatase which plays an important role in regulating cell growth. Mutation in PTEN gene results in loss of protein function leading to uncontrolled cell proliferation and hamartomatous growths.

Extractions: The Genetics of Colon Cancer Knowledge of the genetics of colorectal cancer has accumulated rapidly during the last decade. The genes responsible for the inherited syndromes of familial adenomatous polyposis (FAP) and hereditary nonpolyposis colorectal cancer (HNPCC) have been identified and genetic testing is commercially available. The genes involved in the pathogenesis of the rare hamartomatous polyposis syndromes have also been identified. The inherited syndromes of colon cancer and colonic polyposis are listed in Table 2. Table 2: Inherited Syndromes of Colon Cancer and Colonic Polyps Syndromes with adenomatous polyps Familial adenomatous polyposis (FAP) Gardener syndrome Turcot syndrome Attenuated adenomatous polyposis coli Hereditary nonpolyposis colorectal cancer; Lynch syndromes I and II (HNPCC) Syndromes with hamartomatous polyps Peutz-Jeghers syndrome Juvenile polyposis syndromes Cowden syndrome Syndromes with Adenomatous Polyps Familial adenomatous polyposis (FAP) FAP is an autosomal dominantly inherited condition characterized by the development of hundreds to thousands of colonic adenomatous polyps and a near 100% risk for cancer of the colon if the colon is not removed. Polyps begin to emerge at an average age of 16 years and, if left untreated, one or more of the polyps will progress to cancer by the average age of 44 years. Several variants of FAP include the Gardner syndrome, which is characterized by extracolonic manifestations of osteomas, skin fibromas and epidermoid cysts. In the Turcot syndrome there are accompanying CNS malignancies, notably medulloblastoma. A recently described variant of FAP is attenuated adenomatous polyposis coli in which affected persons exhibit about 30 colonic adenomas and have an approximately 10-year delay in cancer occurrence.
PTEN Intro

http://www.endometrium.org/PTEN Central/Docs/pten_intro.htm

Extractions: PTEN: An Introduction PTEN is a tumor suppressor The PTEN tumor suppressor gene is a dual specificity phosphatase located on chromosome 10 (10q23) that acts through an Akt-dependent pathway to suppress cell division ands enable apoptosis Its role in tumor suppression is confirmed by frequent endometrial abnormalities which develop in PTEN-deficient mice and high incidence of breast, thyroid, and endometrial cancers in humans with constitutive mutation of one PTEN allele, Cowdens syndrome Nomal Endometrial Expression (above figs.) is hormone dependent : Endometrial gland PTEN expression changes with the hormonal environment during the normal menstrual cycle . Estrogenic conditions (proliferative) produce very high epithelial expression (left panel above). Progesterone exposure during the secretory phase initially creates PTEN-free secretory vacuoles, then progressive depletion of PTEN protein (middle 2 panels, above). PTEN protein eventually disappears from glands, and remains so during menses (right, above). Stromal expression remains high throughout the cycle, but with variation in relative intensity between nuclear and cytoplasmic compartments. If presence of a gene product corresponds to a functional requirement, it might be inferred that under progestin rich conditions of secretory endometrium the tumor suppressive activities of the PTEN protein are unnecessary.
