New gene for rheumatism identified

29.10.2002


A genetic variant that can explain the occurrence of a type of rheumatic disorder called SLE has been identified by a research team at Uppsala University, Sweden. The team, led by Associate Professor Marta Alarcón at the Rudbeck Laboratory, is presenting its finding in the latest issue of the scientific journal Nature Genetics.



Nearly 6,000 predominantly young women are victims of systemic lupus erythematosus, SLE. The disease is partly genetic and causes damage to the skin and various organs. The genetic variant in the gene PDCD1 was identified in families with at least two persons suffering from the ailment. Genetic analyses have shown that the part where the gene PDCD1 is located in chromosome 2 is implicated in the disease.

The research team has determined the position of the gene with still greater precision and has sequenced the whole gene. They found several variants, but only one of them repeatedly turned up in the family members with the sickness. In order to make certain that the variant is associated with the ailment, the team studied nearly 2,500 individuals including families in the US. The variant is found in some of the patients and can explain one of the mechanisms behind the development of the disease. The genetic variant in the PDCD1 gene can modify the normal function and expression of the gene, but it is still unclear exactly how.


However, the discovery of this variant makes it possible to move on and examine how various combinations of genes work together to cause the illness. The discovery of this gene variant for SLE is, after a gene variant for Crohn’s disease, the second in the world to be identified for a so-called autoimmune disorder, that is, a disease in which cells from the immune defense produce antibodies to attack the body’s own tissues. It is also one of the few variants to be identified for what are called complex diseases, that is, diseases like heart attacks, high blood pressure, and schizophrenia.

The discovery reported by the research team at Uppsala can improve genetic diagnostics in the future and can contribute to the creation of better therapies for victims of the disorder.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
