Enabling Down Syndrome Research through a Knowledge Graph-Driven Analytical Framework
The NIH INCLUDE initiative, addressing the complexities of Down syndrome (DS) research, has been significantly advanced by a novel knowledge graph-driven analytical framework. This platform transforms fragmented data from nine diverse INCLUDE studies, encompassing over 7,000 participants and 37,000 biospecimens, into a unified, semantically rich infrastructure. By integrating domain-aware RDF schemas and enriching data with external knowledge like the Monarch Initiative (adding 4,281 genes and 7,077 variants), the framework creates over 1.6 million semantic associations. This AI-ready knowledge graph enables sophisticated analyses, including path-based reasoning and graph embeddings, which achieved 92% accuracy in predicting DS status. It also facilitated the discovery of 79 shared phenotypes linked to JAK-STAT pathway genes, validating its utility for systematic genotype-phenotype exploration, cross-study pattern recognition, and predictive modeling.

Predictive Accuracy for DS Status
Utilizing advanced graph embeddings, our model demonstrates high confidence in predicting Down Syndrome status, showcasing the power of latent graph representations for clinical insights. A Random Forest classifier trained on participant embeddings from the merged ALL KG achieved 92% accuracy in predicting DS status. This strong performance, with high precision (0.93) and recall (0.98) for T21 participants, underscores the potential of AI-ready KGs for precision diagnostics and patient stratification.

JAK-STAT Pathway Gene-Phenotype Discovery
Through graph analysis, we identified shared phenotypic associations with key JAK-STAT pathway genes, providing concrete examples of novel discovery.
Targeted Pathway Analysis: Focusing on JAK-STAT pathway genes (JAK1, JAK2, JAK3, STAT1, STAT2, STAT3), our path-based analysis extracted all connections leading to phenotypes or conditions associated with participants. This method identified 79 shared phenotypes across these genes. A subset of these included Hypothyroidism (HP:0000821), Skin rash (HP:0000988), Vitiligo (HP:0001045), and Developmental delay (HP:0001629), aligning with known comorbidities in the reference literature. This demonstrates the framework's ability to systematically identify genotype-phenotype associations and support hypothesis generation for further functional and clinical studies.
