Family History DNA Sleuths Run Risk of Uncovering Infertility

28.04.2005


A simple DNA test that is available commercially to help people establish their ancestry could in fact disclose male infertility claims a new study from the University of Leicester.



The world renowned Department of Genetics - the UK’s top rated research Genetics department where DNA genetic fingerprinting was discovered - has published a paper, Inadvertent diagnosis of male infertility through genealogical DNA testing, in the Journal of Medical Genetics.

Report author Professor Mark Jobling warns that DNA testing to disclose family history runs the risk of revealing whether or not you can procreate - and he warns commercial companies to steer clear of this level of genetic detail in their genealogical searches.


Professor Jobling said: “More and more people are turning to DNA testing to throw light on their ancestry, or genealogical relationships. Much of this testing is of DNA markers on the Y chromosome in men, and companies are vying with each other to offer more sophisticated tests with more and more markers.

“However, some of these markers lie in regions of the Y chromosome that can be lost, causing male infertility. So in principle, a genealogical DNA test can actually diagnose infertility in a client.

“In our study of over 3000 men we show that these kinds of ’deletions’ can indeed be found in ordinary population samples, rather than selected men from fertility clinics, highlighting this as an ethical issue. We recommend that testing companies avoid markers that lie in the commonly deleted regions.”

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
