Diabetes subtypes traced to different genetic drivers

Researchers working from Lund University's ANDIS study, with replication in Finland's DIREVA and Botnia cohorts, ran genome-wide association and genetic risk score analysis on five previously identified type 2 diabetes subtypes. One finding stood out: the severe insulin-resistant subtype associated with a genetic risk score for fasting insulin, but not with TCF7L2 variants or insulin-secretion risk scores. A variant near the LRMDA gene, rs10824307, associated uniquely with mild obesity-related diabetes.

The results point to distinct genetic causes behind some diabetes subtypes, which could eventually shape more tailored research directions.
