    Researchers identified DNA methylation signatures that distinguish high-risk prediabetes clusters, aiding in metabolic risk stratification.

  • 2

    The study utilized genome-wide DNA methylation profiling in two cohorts, achieving over 95% classification accuracy for prediabetes clusters.

  • 3

    1,557 stable CpG sites were identified as predictors of cluster membership, with specific markers linked to distinct metabolic pathways.

  • 4

    The findings suggest that blood-based biomarkers could replace extensive clinical tests like oral glucose tolerance testing.

  • 5

    The study's population was limited to Central European ancestry, and further validation is necessary to assess predictive value for T2D.
