Study Explains Link between Genetic Variation and Vaccine Specificity and Persistence

To better explain how genetic variation affects antibody production and specificity following immunization, researchers conducted a GWAS (genome-wide association study) to examine the persistence of immunity following administration of three childhood vaccines. More...

Genetic Locus Linked to Diabetic Peripheral Neuropathy in Type II Diabetes

Results of a genome-wide association study (GWAS) have identified a genetic locus linked to the development of diabetic peripheral neuropathy (DPN) by individuals suffering from type II diabetes. More...

Polygenic Risk Scores Accurately Predict Risk of Coronary Artery Disease

Polygenic risk scores (PRS) based on an individual's genome sequence are emerging as potentially powerful biomarkers to predict the risk to develop coronary artery disease (CAD). More...

Stress-Induced tRNA Fragments Prove Early Predictors of Epileptic Seizures

 Elevated levels of stress-induced fragments of transfer RNA in the blood may serve as biomarkers that indicate potential for an epileptic seizure hours before the event actually occurs. More...

cfDNA Testing Accurately Detects Fetal Trisomies in Twin Pregnancies

 Results presented in a recently published paper indicated that the performance of cfDNA (cell-free DNA) testing for trisomy 21 (Down syndrome) in twin pregnancy was similar to that reported in singleton pregnancy and was superior to that of the first‐trimester combined test or second‐trimester biochemical testing.

Disease-Related Epigenetic Variations Summarized in New DNA Methylation Atlas

A new DNA methylation atlas summarized a previously unexplored molecular level of human individuality called correlated regions of systemic interindividual variation (CoRSIVs), which may provide a resource for future population-based investigations into how interindividual epigenetic variation modulates risk of disease.

Machine Learning Approach Detects Cancer by Analyzing DNA in Blood Samples

Researchers have described a proof-of-principle approach for the screening, early detection, and monitoring of human cancer based on a machine learning approach that evaluates fragmentation patterns of cell-free DNA across the genome. More...
