About This Project
ZaTxGNN uses the TxGNN deep learning model published by Harvard’s Zitnik Lab in Nature Medicine to predict potential new therapeutic uses for SAHPRA-approved medications.
“TxGNN is the first foundation model designed for clinician-centered drug repurposing, integrating knowledge graphs with deep learning to predict drug efficacy for rare diseases.” — Huang et al., Nature Medicine (2023)
