Men transmit multiple sclerosis to their children 2.2 times more often than women

This study involved an investigation of 444 children of an MS-affected father or mother from 3,598 individuals in 206 families to compare the transmission of MS between affected men and women.

Discovery could help identify genes that cause human heart defects

Researchers at UT Southwestern Medical Center have identified a group of fruit fly gene mutations responsible for "broken hearts" in the embryonic stages of development, a discovery that could help identify genes that cause human heart defects.

Paternal relatives and family history of breast cancer

Taking a family history is one of the most accessible genomic screens for breast cancer. However, a history of cancer on the paternal side may not be as well reported.

Genetic link to community makeup and ecosystem evolution

Genes of one organism not only control the characteristics of that individual but also dictate the behavior of thousands of other organisms in a community.

Basal tumours may originate from breast stem cells that have undergone genetic mishaps

Findings support previous speculation that breast stem cells, or very early descendents, are the cells from which basal tumours arise.

Usefulness of BMI is suspect

For years doctors have used the body mass index (BMI), a ratio of height and weight, to characterize the clinical weight status of their patients.

Genetic key to treating deadly fungal infections

University of Minnesota researchers have discovered how a prevalent fungal pathogen that causes 10,000 deaths per year in the United States overcomes the effects of antifungal drugs by duplicating a section of one of its chromosomes.

Research simplifies diagnosis of Charcot-Marie-Tooth disease

Charcot-Marie-Tooth (CMT) disease is the most common hereditary disorder of the peripheral nervous system, leading to a weakening of the muscles in the lower legs, feet and hands as the nerves that run from the spinal cord to the muscles die off.

Loss of Matrilin-3 gene leads to osteoarthritis

A gene that is associated with osteoarthritis and skeletal deformities in people has been shown to be responsible for preventing the onset of osteoarthritis in adult mice, according to a recent study led by Rhode Island Hospital.

Active mind and body slows Alzheimer's progression

Researchers have uncovered the pathways behind the protection offered by environmental stimulation in Alzheimer's disease, further confirming that enhanced mental and physical activity slows neurological decline.

Link between cell's energy use and genome health discovered

While studying how a cell keeps its genetic material intact, scientists at Johns Hopkins got busy alternately knocking out two catalysts vital to managing a yeast cell's energy.

Gene variant increases risk of type 2 diabetes - but healthy lifestyle changes reduce genetic risk

Researchers have confirmed that a gene variant confers susceptibility to type 2 diabetes in participants of the Diabetes Prevention Program (DPP), a large clinical trial in adults at increased risk for developing type 2 diabetes.
