Genetic risk factor involved in cystic fibrosis discovered

Researchers at the University of North Carolina at Chapel Hill have discovered a genetic risk factor for severe liver disease in people with cystic fibrosis. Those who carry a particular variant of the SERPINA1 gene (also known as alpha-1-antitrypsin or alpha-1-antiprotease) are five times more likely to develop cirrhosis and other liver complications than patients who carry the normal version of the gene.

HLA-Cw*0602 gene variation detected as a high risk for psoriasis

A specific genetic region that has been increasingly identified as the strongest genetic link to psoriasis has an even more significant role in the chronic skin disease than has been suspected, University of Utah medical researchers show in a new study.

Relationship between the CD14 variation and the formation of portal lymphoid aggregates discovered

It is still unknown why the natural history of chronic disease caused by hepatitis C virus (HCV), which currently infects 3% of the world's population, varies from mild in some patients to rapidly progressing in others. Age, sex, alcohol consumption and liver sensitivity to gut-derived bacterial endotoxins, were the early factors defined to enhance the risk of fibrosis progression.

New biomarker predicts response to hepatitis C treatment

Researchers have identified the first genetic marker that predicts response to hepatitis C treatments, and a single letter of DNA code appears to make a huge difference. Duke University Medical Center scientists says the biomarker not only predicts who is most likely to respond to treatment and who isn't, but also may explain why there are such different rates of response among racial and ethnic groups, a phenomenon that has puzzled physicians for years.

New understanding of role hyaluronic acid in skeletal growth

Investigators at Burnham Institute for Medical Research (Burnham) and the University of Connecticut Health Center (U.C.H.C.) have gained new understanding of the role hyaluronic acid (HA) plays in skeletal growth, chondrocyte maturation and joint formation in developing limbs.

Genetic link to ovarian cancer found

Scientists have located a region of DNA which - when altered - can increase the risk of ovarian cancer according to research published in Nature Genetics today.

Cost effectiveness study looks at potential value of new genetic test for guiding chemotherapy treatment

For the 29,000 patients in the United States with metastatic colorectal cancer, chemotherapy with irinotecan is a standard treatment that has been shown to improve survival. But for more than one in 10 of these patients, a variation in their DNA means that this treatment could result in a severe reduction in their white blood cell count, leading to a high risk of bacterial infection and possible subsequent death.

Discovery of gene linked to follicular lymphoma

California and Arizona researchers have identified a gene variant that carries nearly twice the risk of developing an increasingly common type of blood cancer, according to a study published online today by the science journal Nature Genetics.

Brain imaging (MRI/PET) bring us closer to earlier detection of Alzheimer's

Changes in the brain measured with MRI and PET scans, combined with memory tests and detection of risk proteins in body fluids, may lead to earlier and more accurate diagnosis of Alzheimer's, according to new research reported today at the Alzheimer's Association 2009 International Conference on Alzheimer's Disease (ICAD 2009) in Vienna.

Measuring fragile X mental retardation

Researchers from the University of California, Davis have developed a specific and quantitative means of measuring levels of the fragile X mental retardation 1 (FMR1) protein (FMRP), which is mutated in fragile X syndrome. The related report by Iwahashi et al, "A quantitative ELISA assay for the fragile X mental retardation 1 protein," appears in the July 2009 issue of the Journal of Molecular Diagnostics.

Researchers estimate risk of transmission of Huntington's disease to offspring among male carriers

Researchers from Boston University School of Medicine (BUSM) have quantified the probability of a male who carries a "high normal" variant of the Huntington's Disease (HD) gene having a child who develops the disease. Although thought to be a very rare event, the probability has never been estimated using current information and disease guidelines. The findings, appear on-line in the American Journal of Medical Genetics, may be useful during prenatal genetic counseling.

Genetic marker predicts earlier onset of prostate cancer in Caucasian men

Fox Chase Cancer Center researchers have identified a genetic marker that is associated with an earlier onset of prostate cancer in Caucasian men who have a family history of prostate cancer. If the data are confirmed, the marker may help clinicians personalize prostate cancer screening.

Family-based prevention program helps teens override a gene linked to risky behavior

A family-based prevention program designed to help adolescents avoid substance use and other risky behavior proved especially effective for a group of young teens with a genetic risk factor contributing toward such behavior, according to a new study by researchers at the University of Georgia.

Genetic variations in inflammation pathway may predict risk of invasive bladder cancer

Genetic variations in the inflammation pathway may predict who would respond to Bacillus-Calmette-Guerin (BCG) treatment and who might experience a recurrence among patients with non-muscle invasive bladder cancer, according to data presented at the American Association for Cancer Research 100th Annual Meeting 2009.
