Refining the Genetic Contribution to Type 2 Diabetes Subtypes
Authors' conclusion
We found heterogeneous genetic architectures across clinically defined T2D subtypes in a Middle Eastern population. Our findings provide evidence supporting differential polygenic burden, subtype genetic associations and subtype-associated biological pathways across T2D subtypes.
