FEB. 10, 2014 BY SARA WYKES Euan Ashley A small group of patients at Stanford Hospital & Clinics and Lucile Packard Children's Hospital Stanford now can have their DNA deciphered as part of a new pilot program. The goal of the program, the Clinical Genomics Service, is to help doctors better diagnose and treat genetic conditions. In the pilot phase, genomic testing will be limited to patients with "mystery" diseases (typically children), patients with unexplained hereditary cancer risk, patients with inherited cardiovascular or neurological disease, and those with severe, unexplained drug reactions. Potential participants must be referred by a physician, and the clinical genomics team will then determine whether patient cases are suitable for sequencing. "I am very excited to bring the pioneering work of Stanford genomic scientists directly to the bedside of our patients," said Euan Ashley, MCRP, DPhil, associate professor of medicine and of genetics and co-director of the new Clinical Genomics Service. "Because of the foresight and support of our leadership, we have a remarkable opportunity to bring world-leading Stanford science to Stanford patients fast and first." The service will use an integrated approach that includes professional genetic counseling, the most advanced genome sequencing technology available and … Continue reading →

PUBLIC RELEASE DATE: 6-Feb-2014 Contact: Michael C. Purdy 314-286-0122 Washington University School of Medicine A genetic disorder that affects about 1 in every 2,500 births can cause a bewildering array of clinical problems, including brain tumors, impaired vision, learning disabilities, behavioral problems, heart defects and bone deformities. The symptoms and their severity vary among patients affected by this condition, known as neurofibromatosis type 1 (NF1). Now, researchers at Washington University School of Medicine in St. Louis have identified a patient's gender as a clear and simple guidepost to help health-care providers anticipate some of the effects of NF1. The scientists report that girls with NF1 are at greater risk of vision loss from brain tumors. They also identified gender-linked differences in male mice that may help explain why boys with NF1 are more vulnerable to learning disabilities. "This information will help us adjust our strategies for predicting the potential outcomes in patients with NF1 and recommending appropriate treatments," said David H. Gutmann, MD, PhD, the Donald O. Schnuck Family Professor of Neurology, who treats NF1 patients at St. Louis Children's Hospital. The findings appear online in the Annals of Neurology. Kelly Diggs-Andrews, PhD, a postdoctoral research associate in Gutmann's laboratory, … Continue reading →

The findings may guide the search for improved treatments for heart disease. Most of us have heard of "good cholesterol" and "bad cholesterol" coursing through our bloodstream. In the conventional health wisdom of the past 30 years, having more of the "good" variety (high-density lipoprotein, or HDL) lowers your risk of heart disease, while more of the bad one (low-density lipoprotein, LDL) increases your risk. Indeed, over the years, clinical trials and other studies have found that drugs that lower LDL also lower your probability of heart disease. On the other hand, drug trials have not shown heart-health benefits to increasing HDL or to lowering triglycerides, a third type of blood lipid. Now a new study co-led by scientists at The Children's Hospital of Philadelphia and Penn Medicine sheds light on the role of genes and blood lipid levels in cardiovascular health. Newer tools for gene analysis show how variations in DNA are underlying … Continue reading →
