Is whole genome sequencing the new first-line test for children with genetic diseases?

Posted by Katherine Lawless on Tue, Feb 19, 2019 @ 13:02 PM

Congenital anomalies and genetic disorders are the leading cause of death in children less than ten years old and affect about six percent of live births. For children with suspected genetic disorders, it is crucial to establish an early etiologic diagnosis for a prompt implementation of precision medicine and to enable optimal outcomes to guide clinical decisions. The challenge, however, is the lack of etiologic diagnosis.

Oral swabs for pharmacogenomics: A comparative study of DNA quality and performance

Posted by Katherine Lawless on Tue, Feb 05, 2019 @ 13:02 PM

Pharmacogenomics is a growing field that tailors dosage and drug choices based on patient genetic profiles with the potential to benefit millions of patients with personalized medical care while changing the world of medicine as we know it. One of the key obstacles faced by those working in pharmacogenomics is DNA sample collection. Traditionally, clinicians have used blood samples for DNA collection which are costly (requiring phlebotomy and cold chain logistics) and invasive (hindering patient compliance), making the clinical integration of pharmacogenomics difficult. Many researchers are turning to the idea of buccal and/or saliva swabs as a less costly and non-invasive alternative to DNA collection. However, the question is are these sample types of high enough quality for analysis?

3 trends within high-impact genomics you may not know about

Posted by Katherine Lawless on Wed, Nov 28, 2018 @ 13:11 PM

Our knowledge of science is constantly changing and improving as new discoveries drive us forward in the modern world. Genomics is no exception. We witness these trends all around us either within the publications we read about new studies, in the news, or perhaps even through blogs such as this one.  For example, I recently attended the American Society of Human Genetics conference in San Diego where I picked up a copy of Cell Press’s Trends Limited Edition High-Impact Genomics, Vol. 3 (link to document) which highlights particularly impactful genomics reviews. It captured my interest and I wanted to share a few highlights with you.
