A Search for Early Brain Biomarkers in a Mouse Model of KCNQ2-DEE

Published on February 24, 2026

Excerpt

Using several types of non-invasive imaging techniques (MRI, DTI, PET), scientists tracked how the brain develops in mice carrying a variant in the KCNQ2 gene that has been linked to developmental and epileptic encephalopathy (DEE).

What It’s About 

Researchers scanned the brains of mice throughout development, from early juvenile stages all the way into adulthood. They found subtle changes in how different brain regions were communicating with each other. Because most everyday activities require multiple brain regions to work together, when this coordination is off (whether too much or too little), it can affect how we function. In this study, they found that some brain networks were overactive early on, but then became less coordinated by adulthood.

Why It Matters 

The same imaging tools used in this study can also be used in people. This means that discoveries made in these mice could eventually help individuals with KCNQ2-DEE by:

  • Identifying early warning signs 
  • Improving diagnosis
  • Guiding treatment decisions at earlier stages

The Quick Term 

Biomarker: A measurable sign in the body that is linked to a specific condition. They can be things like levels of certain substances in the blood or different patterns of brain activity.
