Diagnostic criteria for Christianson Syndrome

Diagnostic criteria for Christianson Syndrome

Because the severe autism-like condition Christianson Syndrome was only first reported in 1999 and some symptoms take more than a decade to appear, families and doctors urgently need fundamental information about it. Continue reading

Genetic risk for autism stems mostly from common genes

Genetic risk for autism stems mostly from common genes

Using new statistical tools, Carnegie Mellon University’s Kathryn Roeder has led an international team of researchers to discover that most of the genetic risk for autism comes from versions of genes that are common in the population rather than from rare variants or spontaneous glitches. Published in the July 20 issue of the journal Nature Genetics , the study found that about 52 percent of autism was traced to common genes and rarely inherited variations, with spontaneous mutations contributing a modest 2.6 percent of the total risk Continue reading

Genetic cause of common breast tumors found

Genetic cause of common breast tumors found

A multi-disciplinary team of scientists from the National Cancer Centre Singapore, Duke-NUS Graduate Medical School Singapore, and Singapore General Hospital have made a major breakthrough in understanding the molecular basis of fibroadenoma, one of the most common breast tumors diagnosed in women.

Metabolic enzyme stops progression of most common type of kidney cancer

Metabolic enzyme stops progression of most common type of kidney cancer

In an analysis of small molecules called metabolites used by the body to make fuel in normal and cancerous cells in human kidney tissue, a research team from the Perelman School of Medicine at the University of Pennsylvania identified an enzyme key to applying the brakes on tumor growth.

Immune cell’s role in intestinal movement may lead to better understanding of irritable bowel syndrome

Immune cell’s role in intestinal movement may lead to better understanding of irritable bowel syndrome

Learning the role of immune-system cells in healthy digestive tracts and how they interact with neighboring nerve cells may lead to new treatments for irritable bowel syndrome (IBS). Researchers from Penn State College of Medicine, in collaboration with other scientists, have reported the role of macrophages in regulating the contractions of the colon to push digested material through the digestive tract. The muscular lining of the intestine contains a distinct kind of macrophage, an immune system cell that helps fight infections Continue reading

Genetic variations may modify cardiovascular benefit of aspirin

Genetic variations may modify cardiovascular benefit of aspirin

Aspirin is the gold standard for antiplatelet therapy and a daily low-dose aspirin is widely prescribed for the prevention of cardiovascular disease. Now, a new study suggests that common genetic variation in the gene for catechol-O-methyltransferase (COMT) may modify the cardiovascular benefit of aspirin, and in some people, may confer slight harm Continue reading
