CRISPR Editing in Zebrafish Congenital Heart Defect Models

Technology Overview

Led by Dr. Lisa Maves, one goal of the Maves Lab at Seattle Children’s Research Institute is to understand the genetic mechanisms involved in building the heart. They are taking advantage of CRISPR-Cas9 genome editing technology, and of zebrafish as an animal model system, to identify the genetic causes of congenital heart defects. In particular, they are engineering zebrafish to carry the same DNA mutations that are found in human patients with heart defects. These approaches allow the Maves Lab to use the zebrafish to understand how specific genes work to properly form the heart. Because the zebrafish’s DNA and early heart development are very similar to that in humans, their work will have direct relevance for understanding human heart development and congenital heart defects. Insight from their work will allow for more precise genetic screening and counseling for congenital heart defect patients and their families.

With their expertise in using CRISPR-Cas9 genome editing technology in zebrafish, the Maves Lab has the capabilities to engineer knock-out and precise knock-in zebrafish strains. The Maves Lab has the ability to apply these tools not just to genetic loci involved in congenital heart defects, but to genes involved in other diseases as well. In particular, the Maves Lab is able to engineer patient-specific fish, with the goal of using CRISPR-engineered zebrafish models to better understand human disease. The aquatics facility at Seattle Children’s Research Institute is well-equipped with tools for using CRISPR-Cas9 in zebrafish.
