Novel type 1 diabetes polygenic scores improve identification of type 1 diabetes in diverse populations

Most polygenic scores (PS) for type 1 diabetes were developed using European (EUR) ancestry datasets, limiting performance in non-European (non-EUR) populations. We evaluated novel type 1 diabetes PS across diverse populations to assess whether newer models improve prediction in underrepresented populations. Seven type...

Evaluation of functional annotation-informed and ancestry-specific polygenic risk scores for ischemic stroke

Introduction Ischemic stroke (IS) is a leading cause of morbidity and mortality, and predicting events remains challenging. Polygenic risk scores (PRSs) aggregate genetic variants, but performance varies across ancestries and remains modest, particularly in non-European populations. Methods We compared Bayesian PRS met...

Improving performance of polygenic risk scores for hypertension across two ancestry groups

Both annotations and the updated LD panel improved the scores in both ancestry groups, but did not make the scores more equitable across the groups.
