Multiplexed Reference Materials as Controls for Cardiomyopathy Diagnostic Next-Generation Sequencing

Category: clinical genomics, NGS

Posted by Dale Yuzuki on Dec 13, 2016 12:00:00 AM
Hypertrophic Cardiomyopathy (HCM) is a disease where the heart muscle is enlarged and a significant cause of sudden cardiac death, and is frequently asymptomatic.  HCM is commonly caused by a mutation in one of nine heart muscle genes that comprise the sarcomere, and occurs at a prevalence of about 1 in 500 in the general population. HCM is the leading cause of cardiac death in young athletes in the United States. Clinical genetic testing for mutations in the HCM-related genes has been ongoing for over a decade;  the GeneTest.org database reveals 105 laboratories offering some version of genetic testing.  While knowledge of prevalent pathogenic variants are available, the majority of variants remain private (that is, unpublished and not widely available). The move to NGS-based gene panels for HCM testing has lead to new challenges for test development, validation and routine quality control due to the inherent scarcity of samples, the cost of including numerous single mutations from these individual samples, and the lack of these materials for laboratories without a long history of testing.

Mary-Claire King at the European Society for Human Genetics 2016

Mary-Claire King is Professor of Genome Sciences and of Medicine (Medical Genetics) at the University of Washington (Seattle, WA), who first described a single gene on chromosome 17q21 (which she named BRCA1) being responsible for breast and ovarian cancer in many families. This work, published in Science in 1990, also revolutionized the study of many other common, single-gene diseases that are inherited in nature, and led to the discovery of BRCA2.

Guest author: Han Joo Lee, Ph.D., SeraCare Technical Product Manager A cursory look at recent Zika Virus outbreak news headlines is alarming enough: “Zika Virus birth defects may be the ‘Tip of the Iceberg’, experts say”; “Brain damage in Zika babies is far worse than doctors expected”; and “Zika mutates extremely quickly, which is why it’s so scary”. In addition, for the United States the estimated range maps of the Aedes aegypti and Aedes albopictus have been recently updated, widening the range previously reported to all but 10 states within the US.

Posted by Dale Yuzuki on May 2, 2016 12:00:00 AM
At the American Association for Cancer Research conference recently held in New Orleans, LA (April 16 - April 20, 2016) one theme that generated considerable interest was circulating tumor DNA detection, sometimes called liquid biopsy (although that term also encompasses circulating tumor cells). A few of the ctDNA presentations are highlighted below.
