Uppsala researchers in Nature: Mutation in non-coding DNA makes pigs more muscular and less fat
Researchers at Uppsala University and the Swedish University for Agricultural Sciences (SLU) report in the latest issue of Nature that they have identified a regulatory mutation in a gene for a known growth factor that makes pigs more muscular and less fat than wild boars. Most characteristics, such as common diseases like diabetes, have a... view more... (2003-10-21)
Second breast cancer may be greater than thought for high-risk women without BRCA mutations
A preliminary analysis of ongoing research suggests that high-risk women with breast cancer who do not have a BRCA1/2 mutation may face a greater chance for developing a second breast cancer than previously thought. With the increased risk of cancer in these women, should sentinel node biopsy be considered at the time of prophylactic mastectomy,... view more... (2008-05-05)
Increased ovarian cancer risk not found in women with breast cancer family history
Women with a strong family history of breast cancer but who don't have breast cancer genetic mutations can now be reassured that they are not at increased risk for ovarian cancer. view more (2005-09-21)
Enzyme doesn't act alone in atrial fibrillation
An overactive enzyme is behind a leaky calcium channel that plays a role in the development of atrial fibrillation, which is the most common cardiac arrhythmia that is responsible for a third of all strokes. view more (2009-06-18)
Genetic analysis reveals range of Rett syndrome
The first comprehensive analysis of the clinical effects of genetic mutations involved in Rett syndrome will enable affected families to receive a more accurate indication of their child's prognosis. view more (2008-03-11)
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)
Not only the gene itself, its abnormal regulation can also trigger short stature
A specific gene is particularly frequently involved in the development of short stature. Researchers in Heidelberg have now discovered that sequences of genetic material on the X and Y chromosome that regulate this gene are also crucial for growth in children. view more (2009-08-26)
Seasonal Affective Disorder May Be Linked to Genetic Mutation, Study Suggests
With the days shortening toward winter, many people will begin to experience the winter blahs. For some, the effect can be devastating. view more (2008-11-04)
Biologists Discover Why 10% Of Europeans Are Safe From HIV Infection
Biologists at the University of Liverpool have discovered how the plagues of the Middle Ages have made around 10% of Europeans resistant to HIV. view more (2005-03-09)
Genetic mutation found in peripheral artery disease
The finding, appearing online in the journal Circulation, is the first to document a genetic mutation linked to PAD. Although the work was done in mice, researchers say it is likely to give them new insight into how PAD develops and progresses in humans. view more (2008-02-22)
Scripps research scientists find new genetic mutation that halts the development of lupus
The lupus-suppressing action is the result of what is known as a nonsense mutation of the Coronin-1A gene (Coro1a) required for the development of the disease. view more (2008-01-18)
Genetic links to fungal infection risk identified
Two genetic mutations that may put individuals at increased risk of fungal infections have been identified by scientists from UCL and Radboud University, increasing understanding about the genetic basis of these infections and potentially aiding the development of new treatments. view more (2009-10-29)
Researchers find a common genetic risk factor for Parkinson's disease in Asians
Researchers at Mayo Clinic in Jacksonville, Fla. and the National Taiwan University Hospital in Taipei, Taiwan have discovered what to date appears to be the most common genetic risk factor for Parkinson's disease worldwide. view more (2007-01-18)
New model to aid pancreatic cancer research
Vanderbilt-Ingram Cancer Center researchers have developed a new animal model for pancreatic cancer that exhibits a high degree of similarity to human tumors. view more (2006-11-15)
Clues to gene expression in cystic fibrosis will guide research
Genetics tests could help provide cystic fibrosis (CF) patients with targeted treatment in future, pilot study authors suggest. Results from a French clinical trial published today in BMC Medicine show how a small percentage of CF sufferers with a rare genetic stop mutation responded positively to gentamicin treatment. view more (2007-03-29)
Beautiful plumage: Feather color and sex start the species revolution
Faculty of 1000, the leading scientific evaluation service, has highlighted research providing evidence for the evolution of a new species. view more (2009-08-06)
Species evolve to the brink of evolution
A biologist at The University of Texas at Austin has presented a new theory that sheds light on how organisms, including viruses like HIV, rapidly evolve in the face of vaccines and antibiotics. view more (2005-08-29)
Researchers genetically link Lou Gehrig's disease in humans to dog disease
An incurable, paralyzing disease in humans is now genetically linked to a similar disease in dogs. Researchers from the University of Missouri and the Broad Institute have found that the genetic mutation responsible for degenerative myelopathy (DM) in dogs is the same mutation that causes amyotrophic lateral sclerosis (ALS), the human disease also... view more...

Researchers link genetic errors to schizophrenia
A team of researchers at the University of Washington and Cold Spring Harbor Laboratories has uncovered genetic errors that may shed light on the causes of schizophrenia. view more (2008-03-28)
Benefit of cancer prevention surgery differs between women with BRCA1 and BRCA2 mutations
The surgical removal of the ovaries has been widely adopted as a cancer-risk-reducing strategy for women with either BRCA1 or BRCA2 mutations. view more (2008-02-12)
