New gene variants alter type 2 diabetes risk predominantly through reduced beta-cell function
Bibliographic record
Abstract
PURPOSE OF REVIEW: Over the past 18 months, the number of gene loci robustly associated with type 2 diabetes has risen from three to 18. In this study, we focus on explaining the genome-wide approach that has led to most of these discoveries and discuss some of the early insights the new gene loci have provided into the aetiology of type 2 diabetes. RECENT FINDINGS: Recent genome-wide association studies have provided an important resource for furthering our understanding of type 2 diabetes disease mechanisms. Genes previously unsuspected of playing a role in diabetes are now implicated in the disease process. These include genes in cell cycling control (CDKN2A/2B, CDKAL1), transcription factors (TCF7L2, HHEX), and ion channels (SLC30A8). These variants are all associated with insulin-secretory defects in the general population and show little if any relationship to insulin resistance. Two common variants (near or in FTO and MC4R) alter diabetes risk through a primary effect on obesity. SUMMARY: Recent genome-wide association studies show that there are now 18 gene loci associated with the risk of type 2 diabetes. Most of these T2D gene loci affect insulin secretion.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
