Movie star Angelina Jolie tested positive for a "faulty gene" at the center of a high-profile legal battle in the United States that challenges whether human genes can belong to a corporation. http://medicalxpress.com/news/2013-05-jolie-mastectomy-spotlights-legal-genes.html Cancer Thu, 16 May 2013 04:20:01 EST news287893831 Actress Angelina Jolie has today written an op-ed in the New York Times explaining that she has opted to have a double mastectomy because she carries the hereditary BRCA1 gene, which she says increases her risk of breast cancer by 87%. Her mother died from cancer after a ten-year struggle at the age of 56. http://medicalxpress.com/news/2013-05-brca1.html Cancer Wed, 15 May 2013 09:30:05 EST news287827418 A new online database combining symptoms, family history and genetic sequencing information is speeding the search for diseases caused by a single rogue gene. As described in an article in the May issue of Human Mutation, the database, known as PhenoDB, enables any clinician to document cases of unusual genetic diseases for analysis by researchers at the Johns Hopkins University School of Medicine or the Baylor College of Medicine in Houston. If a review committee agrees that the patient may indeed have a previously unknown genetic disease, the patient and some of his or her family members may be offered free comprehensive genetic testing in an effort to identify the disease culprit. http://medicalxpress.com/news/2013-03-database-genetic-discoveries.html Genetics Mon, 18 Mar 2013 10:09:33 EST news282820165 People with cystic fibrosis (CF) will be able to access the latest research findings about their condition, volunteer for clinical trials and influence the direction of future scientific studies through a new website being launched later this week.  http://medicalxpress.com/news/2013-01-website-cystic-fibrosis-patients.html Diseases, Conditions, Syndromes Tue, 08 Jan 2013 06:11:13 EST news276847866 University of Massachusetts Amherst researchers, experts in revealing molecular structure by X-ray crystallography, have identified two new small "chaperone" molecules that may be useful in treating the inherited metabolic disorder known as Schindler/Kanzaki disease. This offers hope for developing the first ever drug treatment for this very rare disease. http://medicalxpress.com/news/2012-10-biochemists-path-molecular-chaperone-therapy.html Medical research Tue, 09 Oct 2012 10:38:50 EST news268997920 New research published Online First in The Lancet suggests that a high proportion of severe intellectual disability results from genetic causes that are not inherited.
