Scientists have discovered genes that increase the risk of osteoporosis and fractures

23.04.2012
Researchers at the Sahlgrenska Academy at the University of Gothenburg, Sweden, have identified the genetic variations that are believed to cause osteoporosis.
The study, published in Nature Genetics and involving leading researchers from Sweden and the world, shows among other interesting facts that women with a higher proportion of genetic variations associated with osteoporosis have a more than 50 percent increased fracture risk.

Osteoporosis is a common and a devastating age-related disease about 50 percent of all who have a hip fracture after age 80 die within one year from the time of injury. The consequences of osteoporosis are therefore well-known, but the causes of the disease are largely unknown.

56 genetic regions for bone density
In a groundbreaking international study, which is led partially from the Sahlgrenska Academy, researchers have now succeeded in identifying a total of 56 genetic regions that control bone density in human beings. Fourteen of these genetic variants increase the risk of fractures, the study, which has been published in the world-leading journal Nature Genetics, has shown.
”This is the first time anyone has identified the genetic variants that are so strongly associated with an increased risk of fracture,” comments Claes Ohlsson, a professor at the Sahlgrenska Academy.

Study on 80,000 people
An international consortium, which also involves researchers from Umeå University, Uppsala University and Malmö University, is behind the study. In total, the researchers studied the genetic make-up of a total of 80,000 people and 30,000 fracture cases, making it the world's largest genetic study in this particular area of research.
”We can prove that women who have a large number of genetic variants associated with low bone density have up to a 56 percent higher risk of osteoporosis as compared with women who have a normal set-ups of the same genetic variants,” comments Claes Ohlsson.

Targets for new treatment methods
The results have led to several new findings in bone biology, among other things the researchers identified several important molecular signaling pathways for bone density that can be targets for new treatment methods and therapies.

”In addition to already known proteins and pathways that were confirmed by the study, we are now facing a whole new biology in the field of bone research,” comments Ulrika Pettersson, Associate Professor in the Department of Pharmacology and Clinical Neuroscience, Umeå University, and co-author of the study.

The article ”Genome-wide meta-analysis identifies 56 bone mineral density loci and reveals 14 loci associated with the risk of fracture” has been published in Nature Genetics on 15 April.

The study is part of the EU-funded project: Genetic Factors of Osteoporosis (GEFOS).

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
