Ovarian Cancer Test Measures Biomarker Serum Levels

A new blood test for the diagnosis of ovarian cancer measures serum levels of the biomarker N-glycolylneuraminic acid (Neu5Gc). More...

Childhood Epilepsy Diagnoses Shift with Genomic Reinterpretation

Clinical genomic tests that examine the DNA sequence of large numbers of genes are commonly used in the diagnosis and management of epilepsy in pediatric patients. The permanence of genomic test result interpretations is not known. More...

Cell-Free DNA Sequencing Test for Infectious Disease Analyzed

A number of clinical collaborators testing a cell-free DNA sequencing test for infectious disease reported interim study results and anecdotal evidence of the assay. More...

Genetic Basis of Childhood-Onset Cardiomyopathies Identified

Personalized medicine is one of the goals of the current medical studies, where the understanding of the genetic cause and disease mechanism in each individual will promote tailored forms of treatment. Investigators make an important step in this direction by deciphering genetic causes in children and their implications for treatment decisions. More...

Potential Brain Tumor Liquid Biopsies Developed

Liquid biopsies are fluid samples from patients, for example from the blood or urine, which provide a less invasive way to monitor disease compared to tumor biopsies. A less intrusive test could be hugely beneficial for brain tumors where collecting samples can be difficult and risky for patients. More...

Microsatellite Instability Assay Validated for Cancer Studies

Microsatellite instability (MSI) occurs when mismatch repair proteins (MMR) fail to fix a DNA replication error, leading to frame-shift mutations in a person's genetic code and non-functioning proteins. MSI has acted as a strong marker for genetic conditions such as Lynch syndrome that can lead to a variety of cancers. More...
