Type 2 diabetes genetic loci informed by multi-trait associations point to disease mechanisms and subtypes: a soft clustering analysis
Background Type 2 diabetes (T2D) is a heterogeneous disease for which (1) disease-
causing pathways are incompletely understood and (2) subclassification may improve …
