This new tool offers clinicians the dos and don’ts of genetic testing, what physicians need to know to do it properly
Clinical use of gene sequencing information has advanced to the point where a team of genetic experts has compiled and issued the Genetic Testing Handbook. The goal of the clinical genome and exome sequencing (CGES) handbook is to provide clinicians—including pathologists and clinical laboratory scientists—with a useful reference tool.
The authors of the Genetic Testing Handbook are Leslie G. Biesecker, M.D., of the National Human Genome Research Institute (NHGRI) in Bethesda, Maryland, and Robert C. Green, M.D., M.P.H., a geneticist who is an Associate Professor of Medicine at Harvard Medical School.
Primer Distills Human Genome Project Technologies for Practical Use
“The technologies that were used for the Human Genome Project are now distilled down to practical tools that clinicians can use to diagnose and, hopefully, treat diseases in patients that they couldn’t treat before,” stated Biesecker, who serves as Chief and Senior Investigator at the NHGRI’s Medical Genomics and Metabolic Genetics Branch, in a press release issued by the National Institutes of Health (NIH).

Nano-technology Breakthrough May Prevent Cancers from Metastasizing
With the goal of removing tumor cells from the bloodstream, a biomedical engineering team at the University of Arkansas for Medical Sciences (UAMS) in Little Rock has discovered a non-invasive way to identify cancer and to capture tumor cells in the bloodstream. This landmark discovery, could dramatically improve early cancer diagnosis and prevent deadly metastasis. It could also provide a framework for a new type of diagnostic test that could detect metastatic cancer from a blood sample.
Up to 400 times more sensitive than existing ELISA-based methods
Detecting any of seven cancers in their earliest stages may be feasible through the use of a new biomarker chip that was recently unveiled by scientists from Stanford University’s Center for Magnetic Nanotechnology. To give their biomarker chip increased sensitivity over fluorescent detection methods, the scientists use magnetic technologies to accomplish detection.
Reporting in Proceedings of the National Academy of Sciences (PNAS), lead scientist Shan X. Wang, Ph.D., director of the center and professor of materials science and electrical engineering, says the chip is able to detect very low levels of seven cancers. The biodetection chip is to be marketed by Silicon Valley startup MagArray Inc., of Sunnyvale, California. It detects multiple proteins in blood or DNA strands using magnetic technology similar to how a computer reads a hard drive. Developers say this chip could also be used to diagnose cardiovascular disease and monitor cancer therapy.
