Technology captures tumors'genetic profile, guides cancer treatment
A study led by researchers at Dana-Farber Cancer Institute and Broad Institute of the Massachusetts Institute of Technology and Harvard University provides the first demonstration of a practical method of screening tumors for cancer-related gene abnormalities that might be treated with "targeted" drugs. view more (2007-02-12)
Scripps research scientists identify genetic cause for type of deafness
A team led by scientists from The Scripps Research Institute has discovered a genetic cause of progressive hearing loss. view more (2009-09-04)
Many children with hearing loss also have eye disorders
About one-fifth of children with sensorineural hearing loss also have ocular disorders, according to a report in the February issue of Archives of Otolaryngology-Head & Neck Surgery, one of the JAMA/Archives journals. view more (2009-02-17)
Reduced mitochondrial function important mechanism in aging
Scientists at the Karolinska Institute have found that changes in the "powerhouse" of cells, the mitochondria, play a key role in aging. The findings are being published in this week's issue of the journal Nature. Mitochondria, which provide energy to cells, have their own set of DNA. Mutations of mitochondrial DNA increase with age,... view more... (2004-05-27)
Molecular basis for neurodegeneration in Ataxia telangiectasia
An upcoming paper from Dr. David Wassarman (University of Wisconsin School of Medicine and Public Health) in the May 1 issue of G&D lends new insight into the pathogenesis of neurodegeneration in Ataxia telangiectasia. view more (2008-04-15)
Gene-on-gene interactions may influence risk for developing alcoholism
Not only do both genes and environment have an impact on the development of alcohol-use disorders, but now researchers have found that certain genes may influence scientists' ability to interpret other genes' effects. One variant of the alcohol dehydrogenase (ADH) gene - the ADH1B genotype - appears to be able to influence level of response (LR)... view more... (2006-08-28)
Defective genes increase breast cancer risk in young women to a greater extent than previously estimated
A joint study between St Mary's Hospital, the Paterson Institute, Christie Hospital, The University of Manchester, Guys Hospital in London, and Cambridge University researching breast cancer has found that women with defects in certain genes have a higher chance of developing breast cancer when they are young than previous estimates. The report... view more... (2003-04-02)
Breast cancer risk varies significantly among BRCA1 and BRCA2 carriers
There is a broad variation in the risk of developing breast cancer among people who carry the BRCA1 and BRCA2 gene mutation, according to a study in the January 9/16 issue of JAMA. view more (2008-01-09)
Kidney function discovery sheds light on genetic complexity of disease
To find a cure for cancer, haemophilia and other diseases, researchers need to be looking for complex, interacting genetic factors, according to the authors of a new study. view more (2008-11-26)
Ben-Gurion U. researchers reveal connection between cancer and human evolution
Researchers at Ben-Gurion University of the Negev (BGU) have discovered that gene mutations that once helped humans survive may increase the possibility for diseases, including cancer. view more (2009-07-06)
Evolution follows few of the possible paths to antibiotic resistance
Darwinian evolution follows very few of the available mutational pathways to attain fitter proteins, researchers at Harvard University have found in a study of a gene whose mutant form increases bacterial resistance to a widely prescribed antibiotic by a factor of roughly 100,000. view more (2006-04-12)
Convergent evolution of molecules in electric fish
Having a set of extra genes gave fish on separate continents the ability to evolve electric organs, report researchers from The University of Texas at Austin. view more (2006-03-06)
Varying prevalence among ethnic groups of gene mutation that increases risk of breast cancer
Among several U.S. racial/ethnic groups examined, Hispanic women were found to have the highest prevalence of the cancer-associated gene mutation BRCA1 at 3.5 percent, with Asian Americans having the lowest prevalence (0.5 percent), according to a study in the December 26 issue of JAMA. view more (2007-12-26)
Humans are reason for why domestic animals have strange and varied coat colors
HUMANS have actively changed the coats of domestic animals by cherry-picking rare genetic mutations, causing variations such as different colours, bands and spots, according to a new study. view more (2009-01-16)
Jefferson Scientists Identify Gene Mutation Potentially Involved in Breast Cancer Initiation
Researchers at Jefferson Medical College and the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia and at the Albert Einstein College of Medicine in New York have found evidence suggesting that a mutation in a gene that normally helps block the formation of breast tumors could play a role in the initiation of a major form of... view more...

Researchers identify protein pathway involved in Parkinson disease development
Scientists have found a novel signaling pathway in cells that is altered by genetic mutations recently identified in Parkinson disease development. view more (2007-06-19)
Gene for immune deficiency syndromes found
A newly discovered gene mutation may account for many cases of immune deficiency, in particular two syndromes known as immunoglobulin A (IgA) deficiency and Common Variable Immunodeficiency (CVID), report researchers in the July issue of Nature Genetics. The discovery may lead to a new diagnostic test for these conditions, which make people highly... view more... (2005-07-11)
Safe new therapy for genetic heart disease
A new clinical trial suggests that long-term use of candesartan, a drug currently used to treat hypertension, may significantly reduce the symptoms of genetic heart disease. view more (2008-12-30)
Bats add their voice to the FOXP2 story
When it comes to the FOXP2 gene, humans have had most to shout about. Discoveries that mutations in this gene lead to speech defects and that the gene underwent changes around the time language evolved both implicate FOXP2 in the evolution of human language. view more (2007-09-19)
Getting down to cancer basics
Researchers have identified a new cancer gene - one that is common to many cancers and affects the most basic regulation of our genes. The new example - a gene on the X chromosome called UTX - is found in 10% of cases of multiple myeloma and 8% of esophageal cancers. view more (2009-03-30)
