ObjectivePolygenic scores strongly predict type 1 diabetes risk, but most scores were developed in European-ancestry populations. In this study, we developed a multi-ancestry polygenic score to accurately predict type 1 diabetes risk across diverse populations.

We trained the score in the Mass General Brigham (MGB) Biobank (372 individua...
