Greater oversight needed in sharing of genetic information online

With just $399 and a bit of saliva in a cup, consumers can learn about their genetic risk for diseases from breast cancer to diabetes. Now, thanks to social networking sites set up by personal genomics companies, they can also share that information with family, friends and even strangers on the Internet.

Genomic research lays groundwork for new approaches for treating, preventing skin diseases

The health of our skin - one of the body's first lines of defense against illness and injury - depends upon the delicate balance between our own cells and the millions of bacteria and other one-celled microbes that live on its surface.

In retinal disease, sight may depend on second sites

If two people have the same genetic disease, why would one person go blind in childhood but the other later in life or not at all? For a group of genetic diseases - so-called ciliary diseases that include Bardet-Biedl syndrome, Meckel-Gruber syndrome, and Joubert syndrome - the answer lies in one gene that is already linked to two of these diseases and also seems to increase the risk of progressive blindness in patients with other ciliary diseases. The findings are published online this week at Nature Genetics.

Rarefaction for gene discovery

Researchers at Purdue University have found a way to save time, money and a little frustration in searches for specific genes that shed light on the biological processes associated with all forms of life.

Scientists develop whole-genome sequencing approach to mapping mutations in fruit flies

The Stowers Institute's Hawley Lab and Molecular Biology Facility have developed a "whole-genome sequencing approach" to mapping mutations in fruit flies.

Discovery of genetic marker linked to the risk of acetaminophen-induced liver injury

Acetaminophen (Tylenol and generics) is one of the most commonly used over-the-counter drugs in the United States. While generally safe, acetaminophen is known to cause severe liver injury if taken in high doses. But likely due to genetics, even the recommended dose can induce serious liver damage in a significant number of people.

DNA "barcodes" used to map mosquito species in West Africa that spread lymphatic filariasis

New biotechnologies that allow scientists to quickly and accurately distinguish species based on a simple DNA analysis are being creatively deployed for the first time in the war against a major global disease.

Breakthrough method for sequencing-based methylation profiling

Bioengineers at UC San Diego have developed a breakthrough method for sequencing-based methylation profiling, which could help fuel personalized regenerative medicine and even lead to more efficient and cost-effective methods for studying certain diseases.

Discovery of nine new genes on X chromosome that, when knocked-out, lead to learning disabilities

The international team studied almost all X chromosome genes in 208 families with learning disabilities - the largest screen of this type ever reported.

Discovery of gene variation linked to increased risk of ischemic stroke

Millions of people have a genetic variant linked to increased risk of ischemic stroke, reports an international research team including scientists at The University of Texas Health Science Center at Houston in a study published online by The New England Journal of Medicine on April 15.
