Human geneticists have long debated whether the genetic risk of the most common medical conditions derive from many rare mutations, each conferring a high degree of risk in different people, or common differences throughout the genome that modestly influence risk. A new study by Brigham and Women's Hospital (BWH) researchers has harnessed data and new analysis tools to address this question in four common diseases: rheumatoid arthritis; celiac disease; coronary artery disease and...

Columbia researchers have conducted a study that suggests cells inside intestines could be employed to make insulin for patients with type I diabetes. Previously, researchers considered stem cell transplants to be the only way to replace lost cells inpatients with type I diabetes. Such a discovery could also mean that these patients would be free from daily insulin injections as well. Researchers have been conducting their work on mice and published their results in the journal Nature...

A recent study posted in Nature Genetics explains that researchers have found that Chlamydia has been evolving differently than previously thought. The researchers used whole genome sequencing to find these results. Their findings show the exchange of DNA between different strains of the STD to form new strains is more common than expected. The researchers came about their findings while working with hospitals to improve their testing and detection of Chlamydia, particularly different...

Study suggests a new approach could give patients the ability to make their own insulin-producing cells without a stem cell transplant A study by Columbia researchers suggests that cells in the patient's intestine could be coaxed into making insulin, circumventing the need for a stem cell transplant. Until now, stem cell transplants have been seen by many researchers as the ideal way to replace cells lost in type I diabetes and to free patients from insulin injections. The...

Whole genome analysis of Chlamydia trachomatis highlights risks with current method of tracking In a study released today in Nature Genetics, researchers have found that Chlamydia has evolved more actively than was previously thought. Using whole genome sequencing the researchers show that the exchange of DNA between different strains of Chlamydia to form new strains is much more common than expected. The team highlights that current clinical testing methods do not capture the variation...

A genetic variant that increases the risk of a common type of stroke has been identified by scientists in a study published online in Nature Genetics today. This is one of the few genetic variants to date to be associated with risk of stroke and the discovery opens up new possibilities for treatment. Stroke is the second leading cause of death worldwide (more than one in 10 of all deaths, and over six million deaths annually), and also in developed countries is a major cause of chronic...

Researchers in Lille and Paris demonstrated that mutations in the melatonin receptor gene (melatonin or the "hormone of darkness" induces sleep) lead to an almost sevenfold increase in the risk of developing diabetes. This research, which was published in Nature Genetics on 29 January 2012, could contributed to the development of new drugs for the treatment or prevention of this metabolic disease. Type 2 diabetes is characterized by excess blood glucose and increased resistance to insulin....

Washington University Pediatric Cancer Genome Project provides first evidence linking cancer to mutations in genes involved in DNA organization Researchers studying a rare, lethal childhood tumor of the brainstem discovered that nearly 80 percent of the tumors have mutations in genes not previously tied to cancer. Early evidence suggests the alterations play a unique role in other aggressive pediatric brain tumors as well. The findings from the St. Jude Children's Research Hospital...

Genetics has provided surprising insights into why vaccines used in both the UK and US to combat serious childhood infections can eventually fail. The study, published today in Nature Genetics, which investigates how bacteria change their disguise to evade the vaccines, has implications for how future vaccines can be made more effective. Pneumococcus (Streptococcus pneumoniae) causes potentially life-threatening diseases including pneumonia and meningitis. Pneumococcal infections are...

A study published in Nature Genetics today has found new evidence for a link between the body clock hormone melatonin and type 2 diabetes. The study found that people who carry rare genetic mutations in the receptor for melatonin have a much higher risk of type 2 diabetes. The findings should help scientists to more accurately assess personal diabetes risk and could lead to the development of personalized treatments. Previous research has found that people who work night shifts have a...
