Neurological disorders are the leading driver of global disability and cause 16.8% of global mortality. Unfortunately, most lack disease-modifying treatments or cures. To address disease complexity and heterogeneity in neurological disease, we developed scCIPHER, an AI approach for Contextually Informed Precision HEalthcaRe using deep learning on single-cell knowledge graphs.
We constructed the Neurological Disease Knowledge Graph (NeuroKG), a neurobiological knowledge graph with 132K nodes and 3.98 million edges, by integrating 20 high-quality primary data sources with single-cell RNA-sequencing data from 3.37 million cells across 106 regions of the adult human brain. Next, we pre-trained a heterogeneous graph transformer on NeuroKG to create scCIPHER.
We leverage scCIPHER to make precision medicine-based predictions in neurological disorders across patient phenotyping, therapeutic response prediction, and causal gene discovery tasks, with validation in large-scale patient cohorts.
This is an ongoing research project.
Pytorch implementation of scCIPHER is available in the GitHub repository.
