GATA1 Database

GATA1 Visualization

The GATA1 Database is a curated repository of germline GATA1 variants identified in patients through published literature. Our goal is to provide a comprehensive knowledge base for understanding germline GATA1 disorders.

If you are interested in contributing variants, please contact wlodarskilab@stjude.org

GATA1 transcript version is NM_002049.3. Curated by Lili Kotmayer, MD, PhD. Last updated: 09/30/2025.
