Fast functional testing of genetic variants, from newborn genomes to disease models like zebrafish, is transforming ambiguous DNA findings into confident, real‑time treatment decisions.

In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...

Knowing how human DNA changes over generations is essential to estimating genetic disease risks and understanding how we evolved. But some of the most changeable regions of our DNA have been ...

Haoyu Cheng, Ph.D., assistant professor of biomedical informatics and data science at Yale School of Medicine, has developed ...

Every living organism has its own genetic "blueprint": the source code for how it grows, functions and reproduces. This blueprint is known as a genome. When scientists sequence a genome, they identify ...

Add Yahoo as a preferred source to see more of our stories on Google. A SickKids led study has found that tiny repeated DNA segments called short tandem repeats vary not only in length but also in ...

The newest DNA sequencing technology from Swiss multinational Roche doesn’t measure DNA directly but in fact analyzes a different polymer altogether. The technology is not yet available for sale, but ...

The collection of high-quality genomic DNA remains a major barrier in pediatric and neurodevelopmental research, particularly among children with autism spectrum disorder (ASD) and other neurogenetic ...

Newborn babies admitted to the hospital's neonatal intensive care unit (NICU) rely on the quick decisions and rapid action of the medical team responsible for them. DNA testing is critical to ...

Tiny repeated stretches of DNA in your genome may quietly shape how your body works, how your brain develops and how you respond to disease. A new study from scientists at The Hospital for Sick ...
