More accurate genetic diagnosis for people of African ancestry
Improving Genetic Diagnosis for African Ancestry Populations
This project improves genetic testing for people of African ancestry—especially children with developmental conditions like epilepsy—by adding more African genetic data and better interpretation tools.

What this research studies
Researchers are adding more genetic data from people of African ancestry to public reference databases and testing improved analysis pipelines using samples and clinical information from NeuroDev, NeuroGAP-Psychosis, and gnomAD. They will sequence and analyze DNA from participants (including a large cohort in Kenya), link genetic findings to detailed medical, cognitive, and behavioral testing, and use those results to refine interpretation tools. The improved pipeline will be released on the open-access seqr platform so clinicians and labs can use it. The goal is to shorten diagnostic odysseys and find genetic causes that current databases miss.
Who could benefit from this research
Good fit: People of African ancestry—particularly children with neurodevelopmental disorders, epilepsy, or suspected rare genetic conditions—would be ideal candidates for participation or to benefit from the results.
Not a fit: Patients whose conditions are not suspected to be caused by rare genetic variants, or people from non-African ancestry groups, are less likely to receive direct benefit from this project.
Why it matters
Potential benefit: If successful, this work could lead to faster, more accurate genetic diagnoses for African ancestry patients, enabling better care and access to genetic counseling and treatment options.
How similar studies have performed: Some prior efforts to diversify reference databases have modestly improved diagnostic yields, but applying these methods at this scale to East African clinical cohorts is largely novel.
